## **Overview**

This article provides a comprehensive guide on how to create and customize charts using Aspose.Slides. You will learn how to programmatically add a chart to a slide, populate it with data, and apply various formatting options to match your specific design requirements. Throughout the article, detailed code examples illustrate each step, from initializing the presentation and chart object to configuring series, axes, and legends. By following this guide, you'll gain a solid understanding of how to integrate dynamic chart generation into your applications, streamlining the process of creating data-driven presentations.

## **Create a Chart**
Charts help people to quickly visualize data and gain insights, which may not be immediately obvious from a table or spreadsheet. 


**Why Create Charts?**

Using charts, you get to

* aggregate, condense, or summarize large amounts of data on a single slide in a presentation
* expose patterns and trends in data
* deduce the direction and momentum of data over time or with respect to a specific unit of measurement 
* spots outliers, aberrations, deviations, errors, nonsensical data, etc. 
* communicate or present complex data

In PowerPoint, you can create charts through the insert function, which provides templates used to design many types of charts. Using Aspose.Slides, you can create regular charts (based on popular chart types) and custom charts.

To allow you create charts, Aspose.Slides provides the [ChartType](https://reference.aspose.com/slides/androidjava/com.aspose.slides/ChartType) class. The fields under this class correspond to different chart types.

- <a name="java-create-powerpoint-presentation-chart" id="java-create-powerpoint-presentation-chart"><strong><em>Steps:</em> Create PowerPoint Presentation Chart in Java</strong></a>

_Code Steps:_

1. Create an instance of the [Presentation](https://reference.aspose.com/slides/androidjava/com.aspose.slides/Presentation) class.
2. Get a slide's reference through its index.
3. Add a chart with some data and specify your preferred chart type. 
4. Add a title for the chart. 
5. Access the chart data worksheet.
6. Clear all the default series and categories.
7. Add new series and categories.
8. Add some new chart data for the chart series.
9. Add a fill color for chart series.
10. Add labels for the chart series. 
11. Write the modified presentation as a PPTX file.

This Java code shows you how to create a normal chart:

```java
import com.aspose.slides.*;
import java.awt.Color;

// Instantiates a presentation class that represents a PPTX file
Presentation pres = new Presentation();
try {
    // Accesses the first slide
    ISlide sld = pres.getSlides().get_Item(0);
    
    // Adds a chart with its default data
    IChart chart = sld.getShapes().addChart(ChartType.ClusteredColumn, 0, 0, 500, 500);
    
    // Sets the chart Title
    chart.getChartTitle().addTextFrameForOverriding("Sample Title");
    chart.getChartTitle().getTextFrameForOverriding().getTextFrameFormat().setCenterText(NullableBool.True);
    chart.getChartTitle().setHeight(20);
    chart.setTitle(true);
    
    // Sets the index for the chart data sheet
    int defaultWorksheetIndex = 0;
    
    // Gets the chart data WorkSheet
    IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
    
    // Deletes the default generated series and categories
    chart.getChartData().getSeries().clear();
    chart.getChartData().getCategories().clear();
    int s = chart.getChartData().getSeries().size();
    s = chart.getChartData().getCategories().size();
    
    // Adds new series
    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 1, "Series 1"),chart.getType());
    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 2, "Series 2"),chart.getType());
    
    // Adds new categories
    chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 1, 0, "Caetegoty 1"));
    chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 2, 0, "Caetegoty 2"));
    chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 3, 0, "Caetegoty 3"));
    
    // Takes the first chart series
    IChartSeries series = chart.getChartData().getSeries().get_Item(0);
    
    // Now populates the series data
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 1, 1, 20));
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 50));
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 30));
    
    // Sets the fill color for series
    series.getFormat().getFill().setFillType(FillType.Solid);
    series.getFormat().getFill().getSolidFillColor().setColor(Color.RED);
    
    // Takes the second chart series
    series = chart.getChartData().getSeries().get_Item(1);
    
    // Populates series data
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 1, 2, 30));
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 2, 2, 10));
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 3, 2, 60));
    
    // Sets the fill color for the series
    series.getFormat().getFill().setFillType(FillType.Solid);
    series.getFormat().getFill().getSolidFillColor().setColor(Color.GREEN);
    
    //Create custom labels for each categories for the new series
    // Sets the first label to show Category name
    IDataLabel lbl = series.getDataPoints().get_Item(0).getLabel();
    lbl.getDataLabelFormat().setShowCategoryName(true);
    
    lbl = series.getDataPoints().get_Item(1).getLabel();
    lbl.getDataLabelFormat().setShowSeriesName(true);
    
    // Shows value for the third label
    lbl = series.getDataPoints().get_Item(2).getLabel();
    lbl.getDataLabelFormat().setShowValue(true);
    lbl.getDataLabelFormat().setShowSeriesName(true);
    lbl.getDataLabelFormat().setSeparator("/");
    
    // Saves the presentation with chart
    pres.save("output.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

### **Create Scattered Charts**
Scattered charts (also known as scattered plots or x-y graphs) are often used to check for patterns or demonstrate correlations between two variables. 

You may want to use a scattered chart when 

* you have paired numerical data
* you have 2 variables that pair well together
* you want to determine whether 2 variables are related
* you have an independent variable that has multiple values for a dependent variable

<a name="java-create-scattered-chart" id="java-create-scattered-chart"><strong><em>Steps:</em> Create Scattered Chart in Java</strong></a> |
<a name="java-create-powerpoint-scattered-chart" id="java-create-powerpoint-scattered-chart"><strong><em>Steps:</em> Create PowerPoint Scattered Chart in Java</strong></a> |
<a name="java-create-powerpoint-presentation-scattered-chart" id="java-create-powerpoint-presentation-scattered-chart"><strong><em>Steps:</em> Create PowerPoint Presentation Scattered Chart in Java</strong></a>

1. Please follow the steps mentioned above in [Creating Normal Charts](#creating-normal-charts)
2. For third step, Add a chart with some data and specify your chart type as one of the following
   1. [ChartType.ScatterWithMarkers](https://reference.aspose.com/slides/androidjava/com.aspose.slides/charttype/#ScatterWithMarkers) - _Represents Scatter Chart._
   2. [ChartType.ScatterWithSmoothLinesAndMarkers](https://reference.aspose.com/slides/androidjava/com.aspose.slides/charttype/#ScatterWithSmoothLinesAndMarkers) - _Represents Scatter Chart connected by curves, with data markers._
   3. [ChartType.ScatterWithSmoothLines](https://reference.aspose.com/slides/androidjava/com.aspose.slides/charttype/#ScatterWithSmoothLines) - _Represents Scatter Chart connected by curves, without data markers._
   4. [ChartType.ScatterWithStraightLinesAndMarkers](https://reference.aspose.com/slides/androidjava/com.aspose.slides/charttype/#ScatterWithStraightLinesAndMarkers) - _Represents Scatter Chart connected by lines, with data markers._
   5. [ChartType.ScatterWithStraightLines](https://reference.aspose.com/slides/androidjava/com.aspose.slides/charttype/#ScatterWithStraightLines) - _Represents Scatter Chart connected by lines, without data markers._

This Java code shows you how to create a scattered charts with a different series of markers: 

```java
import com.aspose.slides.*;

// Instantiates a presentation class that represents a PPTX file
Presentation pres = new Presentation();
try {
    // Accesses the first slide
    ISlide slide = pres.getSlides().get_Item(0);

    // Creates the default chart
    IChart chart = slide.getShapes().addChart(ChartType.ScatterWithSmoothLines, 0, 0, 400, 400);
    
    // Gets the default chart data worksheet index
    int defaultWorksheetIndex = 0;
    
    // Gets the chart data worksheet
    IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
    
    // Deletes the demo series
    chart.getChartData().getSeries().clear();
    
    // Adds new series
    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 1, 1, "Series 1"), chart.getType());
    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 1, 3, "Series 2"), chart.getType());
    
    // Takes first chart series
    IChartSeries series = chart.getChartData().getSeries().get_Item(0);
    
    // Adds a new point (1:3) to the series
    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 1), fact.getCell(defaultWorksheetIndex, 2, 2, 3));
    
    // Adds a new point (2:10)
    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 2), fact.getCell(defaultWorksheetIndex, 3, 2, 10));
    
    // Changes the series type
    series.setType(ChartType.ScatterWithStraightLinesAndMarkers);
    
    // Changes the chart series marker
    series.getMarker().setSize(10);
    series.getMarker().setSymbol(MarkerStyleType.Star);
    
    // Takes the second chart series
    series = chart.getChartData().getSeries().get_Item(1);
    
    // Adds a new point (5:2) there
    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 2, 3, 5), fact.getCell(defaultWorksheetIndex, 2, 4, 2));
    
    // Adds a new point (3:1)
    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 3, 3, 3), fact.getCell(defaultWorksheetIndex, 3, 4, 1));
    
    // Adds a new point (2:2)
    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 4, 3, 2), fact.getCell(defaultWorksheetIndex, 4, 4, 2));
    
    // Adds a new point (5:1)
    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 5, 3, 5), fact.getCell(defaultWorksheetIndex, 5, 4, 1));
    
    // Changes the chart series marker
    series.getMarker().setSize(10);
    series.getMarker().setSymbol(MarkerStyleType.Circle);
    
    pres.save("AsposeChart_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

### **Create Pie Charts**

Pie charts are best used to show the part-to-whole relationship in data, especially when the data contains categorical labels with numeric values. However, if your data contains many parts or labels, you may want to consider using a bar chart instead.

8. Add new points for charts and add custom colors for the pie chart's sectors.
9. Set labels for series.
10. Set leader lines for series labels.
11. Set the rotation angle for pie chart slides.
12. Write the modified presentation to a PPTX file

This Java code shows you how to create a pie chart:

```java
import com.aspose.slides.*;
import java.awt.Color;

// Instantiates a presentation class that represents a PPTX file
Presentation pres = new Presentation();
try {
    // Accesses the first slide
    ISlide slides = pres.getSlides().get_Item(0);
    
    // Adds a chart with default data
    IChart chart = slides.getShapes().addChart(ChartType.Pie, 100, 100, 400, 400);
    
    // Sets the chart Title
    chart.getChartTitle().addTextFrameForOverriding("Sample Title");
    chart.getChartTitle().getTextFrameForOverriding().getTextFrameFormat().setCenterText(NullableBool.True);
    chart.getChartTitle().setHeight(20);
    chart.setTitle(true);
    
    // Sets the index for the chart data sheet
    int defaultWorksheetIndex = 0;
    
    // Gets the chart data worksheet
    IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
    
    // Deletes the default generated series and categories
    chart.getChartData().getSeries().clear();
    chart.getChartData().getCategories().clear();
    
    // Adds new categories
    chart.getChartData().getCategories().add(fact.getCell(0, 1, 0, "First Qtr"));
    chart.getChartData().getCategories().add(fact.getCell(0, 2, 0, "2nd Qtr"));
    chart.getChartData().getCategories().add(fact.getCell(0, 3, 0, "3rd Qtr"));
    
    // Adds new series
    IChartSeries series = chart.getChartData().getSeries().add(fact.getCell(0, 0, 1, "Series 1"), chart.getType());
    
    //Populates the series data
    series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 1, 1, 20));
    series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 50));
    series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 30));
    
    // Not working in new version
    // Adding new points and setting sector color
    // series.IsColorVaried = true;
    chart.getChartData().getSeriesGroups().get_Item(0).setColorVaried(true);
    
    IChartDataPoint point = series.getDataPoints().get_Item(0);
    point.getFormat().getFill().setFillType(FillType.Solid);
    point.getFormat().getFill().getSolidFillColor().setColor(Color.CYAN);
	
    // Sets the Sector border
    point.getFormat().getLine().getFillFormat().setFillType(FillType.Solid);
    point.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(Color.GRAY);
    point.getFormat().getLine().setWidth(3.0);
    point.getFormat().getLine().setStyle(LineStyle.ThinThick);
    point.getFormat().getLine().setDashStyle(LineDashStyle.DashDot);
    
    IChartDataPoint point1 = series.getDataPoints().get_Item(1);
    point1.getFormat().getFill().setFillType(FillType.Solid);
    point1.getFormat().getFill().getSolidFillColor().setColor(Color.ORANGE);
    
    // Sets the Sector border
    point1.getFormat().getLine().getFillFormat().setFillType(FillType.Solid);
    point1.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(Color.BLUE);
    point1.getFormat().getLine().setWidth(3.0);
    point1.getFormat().getLine().setStyle(LineStyle.Single);
    point1.getFormat().getLine().setDashStyle(LineDashStyle.LargeDashDot);
    
    IChartDataPoint point2 = series.getDataPoints().get_Item(2);
    point2.getFormat().getFill().setFillType(FillType.Solid);
    point2.getFormat().getFill().getSolidFillColor().setColor(Color.YELLOW);
    
    // Sets the Sector border
    point2.getFormat().getLine().getFillFormat().setFillType(FillType.Solid);
    point2.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(Color.RED);
    point2.getFormat().getLine().setWidth(2.0);
    point2.getFormat().getLine().setStyle(LineStyle.ThinThin);
    point2.getFormat().getLine().setDashStyle(LineDashStyle.LargeDashDotDot);
    
    // Creates custom labels for each of categories for new series
    IDataLabel lbl1 = series.getDataPoints().get_Item(0).getLabel();
    
    // lbl.ShowCategoryName = true;
    lbl1.getDataLabelFormat().setShowValue(true);
    
    IDataLabel lbl2 = series.getDataPoints().get_Item(1).getLabel();
    lbl2.getDataLabelFormat().setShowValue(true);
    lbl2.getDataLabelFormat().setShowLegendKey(true);
    lbl2.getDataLabelFormat().setShowPercentage(true);
    
    IDataLabel lbl3 = series.getDataPoints().get_Item(2).getLabel();
    lbl3.getDataLabelFormat().setShowSeriesName(true);
    lbl3.getDataLabelFormat().setShowPercentage(true);
    
    // Shows Leader Lines for Chart
    series.getLabels().getDefaultDataLabelFormat().setShowLeaderLines(true);
    
    // Sets the Rotation Angle for Pie Chart Sectors
    chart.getChartData().getSeriesGroups().get_Item(0).setFirstSliceAngle(180);
    
    // Saves the presentation with a chart
    pres.save("PieChart_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

### **Create Line Charts**

Line charts (also known as a line graphs) are best used in situations where you want demonstrate changes in value over time. Using a line chart, you can compare lots of data at once, track changes and trends over time, highlight anomalies in data series, etc.

1. Create an instance of the [Presentation](https://reference.aspose.com/slides/androidjava/com.aspose.slides/Presentation) class.
1. Get a slide's reference through its index.
1. Add a chart with default data along with the desired type (in this case, `ChartType.Line`).
1. Write the modified presentation to a PPTX file

This Java code shows you how to create a line chart:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    IChart lineChart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Line, 10, 50, 600, 350);

    pres.save("lineChart.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

By default, points on a line chart are joined by straight continuous lines. If you want to the points to be joined by dashes instead, you can specify your preferred dash type this way:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    IChart lineChart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Line, 10, 50, 600, 350);

    for (IChartSeries series : lineChart.getChartData().getSeries())
    {
        series.getFormat().getLine().setDashStyle(LineDashStyle.Dash);
    }
} finally {
    if (pres != null) pres.dispose();
}
```

### **Create Tree Map Charts**

Tree map charts are best used for sales data when you want to show the relative size of data categories and (at the same time) quickly draw attention to items that are large contributors to each category.

Presentation pres = new Presentation();
try {
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Treemap, 50, 50, 500, 400);
    chart.getChartData().getCategories().clear();
    chart.getChartData().getSeries().clear();

    IChartDataWorkbook wb = chart.getChartData().getChartDataWorkbook();
    wb.clear(0);

    //branch 1
    IChartCategory leaf = chart.getChartData().getCategories().add(wb.getCell(0, "C1", "Leaf1"));
    leaf.getGroupingLevels().setGroupingItem(1, "Stem1");
    leaf.getGroupingLevels().setGroupingItem(2, "Branch1");

    chart.getChartData().getCategories().add(wb.getCell(0, "C2", "Leaf2"));

    leaf = chart.getChartData().getCategories().add(wb.getCell(0, "C3", "Leaf3"));
    leaf.getGroupingLevels().setGroupingItem(1, "Stem2");

    chart.getChartData().getCategories().add(wb.getCell(0, "C4", "Leaf4"));

    leaf.getGroupingLevels().setGroupingItem(2, "Branch2");

    chart.getChartData().getCategories().add(wb.getCell(0, "C6", "Leaf6"));

    leaf = chart.getChartData().getCategories().add(wb.getCell(0, "C7", "Leaf7"));
    leaf.getGroupingLevels().setGroupingItem(1, "Stem4");

    chart.getChartData().getCategories().add(wb.getCell(0, "C8", "Leaf8"));

    IChartSeries series = chart.getChartData().getSeries().add(ChartType.Treemap);
    series.getLabels().getDefaultDataLabelFormat().setShowCategoryName(true);
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D1", 4));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D2", 5));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D3", 3));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D4", 6));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D5", 9));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D6", 9));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D7", 4));
    series.getDataPoints().addDataPointForTreemapSeries(wb.getCell(0, "D8", 3));

    series.setParentLabelLayout(ParentLabelLayoutType.Overlapping);

    pres.save("Treemap.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

## **Update Charts**

<a name="java-update-powerpoint-chart" id="java-update-powerpoint-chart"><strong><em>Steps:</em> Update PowerPoint Chart in Java</strong></a> |
<a name="java-update-presentation-chart" id="java-update-presentation-chart"><strong><em>Steps:</em> Update Presentation Chart in Java</strong></a> |
<a name="java-update-powerpoint-presentation-chart" id="java-update-powerpoint-presentation-chart"><strong><em>Steps:</em> Update PowerPoint Presentation Chart in Java</strong></a>

1. Instantiate a [Presentation](https://reference.aspose.com/slides/androidjava/com.aspose.slides/Presentation) class that represents the presentation containing the chart you want to update.
2. Obtain the reference of a slide by using its Index.
3. Traverse through all shapes to find the desired chart.
4. Access the chart data worksheet.
5. Modify the chart data series data by changing series values.
6. Add a new series and populate the data in it.
7. Write the modified presentation as a PPTX file.

This Java code shows you how to update a chart:

```java
import com.aspose.slides.*;

// Opens the presentation that contains the chart to update
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    // Access first slide
    ISlide sld = pres.getSlides().get_Item(0);

    // Get the chart from the slide
    IChart chart = (IChart)sld.getShapes().get_Item(0);

    // Setting the index of chart data sheet
    int defaultWorksheetIndex = 0;

    // Getting the chart data worksheet
    IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();

    // Changing chart Category Name
    fact.getCell(defaultWorksheetIndex, 1, 0, "Modified Category 1");
    fact.getCell(defaultWorksheetIndex, 2, 0, "Modified Category 2");

    // Take first chart series
    IChartSeries series = chart.getChartData().getSeries().get_Item(0);

    // Now updating series data
    fact.getCell(defaultWorksheetIndex, 0, 1, "New_Series1");// Modifying series name
    series.getDataPoints().get_Item(0).getValue().setData(90);
    series.getDataPoints().get_Item(1).getValue().setData(123);
    series.getDataPoints().get_Item(2).getValue().setData(44);

    // Take Second chart series
    series = chart.getChartData().getSeries().get_Item(1);

    // Now updating series data
    fact.getCell(defaultWorksheetIndex, 0, 2, "New_Series2");// Modifying series name
    series.getDataPoints().get_Item(0).getValue().setData(23);
    series.getDataPoints().get_Item(1).getValue().setData(67);
    series.getDataPoints().get_Item(2).getValue().setData(99);

    // Now, Adding a new series
    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 3, "Series 3"), chart.getType());

    // Take 3rd chart series
    series = chart.getChartData().getSeries().get_Item(2);

    // Now populating series data
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 1, 3, 20));
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 2, 3, 50));
    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 3, 3, 30));

    chart.setType(ChartType.ClusteredCylinder);

    // Save presentation with chart
    pres.save("AsposeChartModified_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

## **Set Data Range for a Chart**

To set the data range for a chart, do this:

1. Instantiate a [Presentation](https://reference.aspose.com/slides/androidjava/com.aspose.slides/Presentation) class that represents the presentation containing the chart.
2. Get a slide's reference through its index.
3. Traverse through all shapes to find the desired chart.
4. Access the chart data and set the range.
5. Save the modified presentation as a PPTX file.

This Java code shows you how to set the data range for a chart:

```java
import com.aspose.slides.*;

// Opens the presentation that contains the chart
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    ISlide slide = pres.getSlides().get_Item(0);
    IChart chart = (IChart)slide.getShapes().get_Item(0);
    
    chart.getChartData().setRange("Sheet1!A1:B4");
    
    pres.save("SetDataRange_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

## **Use Default Markers in Charts**
When you use a default marker in charts, each chart series get different default marker symbols automatically.

This Java code shows you how to set a chart series market automatically:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    ISlide slide = pres.getSlides().get_Item(0);
    IChart chart = slide.getShapes().addChart(ChartType.LineWithMarkers, 10, 10, 400, 400);

    chart.getChartData().getSeries().clear();
    chart.getChartData().getCategories().clear();

    IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
    chart.getChartData().getSeries().add(fact.getCell(0, 0, 1, "Series 1"), chart.getType());
    IChartSeries series = chart.getChartData().getSeries().get_Item(0);

    chart.getChartData().getCategories().add(fact.getCell(0, 1, 0, "C1"));
    series.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 1, 1, 24));
    chart.getChartData().getCategories().add(fact.getCell(0, 2, 0, "C2"));
    series.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 2, 1, 23));
    chart.getChartData().getCategories().add(fact.getCell(0, 3, 0, "C3"));
    series.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 3, 1, -10));
    chart.getChartData().getCategories().add(fact.getCell(0, 4, 0, "C4"));
    series.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 4, 1, null));

    chart.getChartData().getSeries().add(fact.getCell(0, 0, 2, "Series 2"), chart.getType());
    //Take second chart series
    IChartSeries series2 = chart.getChartData().getSeries().get_Item(1);

    //Now populating series data
    series2.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 1, 2, 30));
    series2.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 2, 2, 10));
    series2.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 3, 2, 60));
    series2.getDataPoints().addDataPointForLineSeries(fact.getCell(0, 4, 2, 40));

    chart.setLegend(true);
    chart.getLegend().setOverlay(false);

    pres.save("DefaultMarkersInChart.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

## **FAQ**

### What chart types are supported by Aspose.Slides?

Aspose.Slides supports a wide range of [chart types](https://reference.aspose.com/slides/androidjava/com.aspose.slides/charttype/), including bar, line, pie, area, scatter, histogram, radar, and many more. This flexibility allows you to choose the most appropriate chart type for your data visualization needs.

### How do I add a new chart to a slide?

To add a chart, you first create an instance of the [Presentation](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentation/) class, retrieve the desired slide using its index, and then call the method to add a chart, specifying the chart type and initial data. This process integrates the chart directly into your presentation.

### How can I update the data displayed in a chart?

You can update a chart’s data by accessing its data workbook ([IChartDataWorkbook](https://reference.aspose.com/slides/androidjava/com.aspose.slides/ichartdataworkbook/)), clearing any default series and categories, and then adding your custom data. This allows you to refresh the chart to reflect the latest data.

### Is it possible to customize the appearance of the chart?

Yes, Aspose.Slides provides extensive customization options. You can modify colors, fonts, labels, legends, and other [formatting elements](/slides/androidjava/chart-entities/) to tailor the chart’s appearance to your specific design requirements.
