Create or Update PowerPoint Presentation Charts in PHP

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 quickly visualize data and gain insights that may not be immediately obvious from a table or spreadsheet.

Why Create Charts?

Using charts, you can:

  • 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
  • spot 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 for designing many types of charts. Using Aspose.Slides, you can create both regular charts (based on popular chart types) and custom charts.

Create Clustered Column Charts

This section explains how to create clustered column charts using Aspose.Slides. You’ll learn to initialize a presentation, add a chart, and customize its elements such as title, data, series, categories, and styling. Follow the steps below to see how a standard clustered column chart is generated:

  1. Create an instance of the Presentation class.
  2. Get a reference to a slide using its index.
  3. Add a chart with some data and specify the ChartType::ClusteredColumn type.
  4. Add a title to the chart.
  5. Access the chart’s data worksheet.
  6. Clear all the default series and categories.
  7. Add new series and categories.
  8. Add new chart data for the chart series.
  9. Apply a fill color to the chart series.
  10. Add labels to the chart series.
  11. Save the modified presentation as a PPTX file.

This C# code demonstrates how to create a clustered column chart:

  # Instantiates a presentation class that represents a PPTX file
  $pres = new Presentation();
  try {
    # Accesses the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Adds a chart with its default data
    $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->hasTitle();
    # Sets the first series to show values
    $chart->getChartData()->getSeries()->get_Item(0)->getLabels()->getDefaultDataLabelFormat()->setShowValue(true);
    # Sets the index for the chart data sheet
    $defaultWorksheetIndex = 0;
    # Gets the chart data WorkSheet
    $fact = $chart->getChartData()->getChartDataWorkbook();
    # Deletes the default generated series and categories
    $chart->getChartData()->getSeries()->clear();
    $chart->getChartData()->getCategories()->clear();
    $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
    $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(java("java.awt.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(java("java.awt.Color")->GREEN);
    # Create custom labels for each categories for the new series
    # Sets the first label to show Category name
    $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
    $pres->save("output.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Create Scatter Charts

Scatter charts (also known as scatter plots or x-y graphs) are often used to check for patterns or demonstrate correlations between two variables.

Use a scatter chart when:

  • you have paired numerical data
  • you have two variables that pair well together
  • you want to determine whether two variables are related
  • you have an independent variable that has multiple values for a dependent variable
  1. Follow the steps in Create Clustered Column Charts.
  2. For the third step, add a chart with some data and specify your chart type as one of the following:
    1. ChartType::ScatterWithMarkers - Represents a scatter chart.
    2. ChartType::ScatterWithSmoothLinesAndMarkers - Represents a scatter chart connected by curves, with data markers.
    3. ChartType::ScatterWithSmoothLines - Represents a scatter chart connected by curves, without data markers.
    4. ChartType::ScatterWithStraightLinesAndMarkers - Represents a scatter chart connected by lines, with data markers.
    5. ChartType::ScatterWithStraightLines - Represents a scatter chart connected by lines, without data markers.

This PHP code shows how to create a scatter chart with different markers for each series:

  # Instantiates a presentation class that represents a PPTX file
  $pres = new Presentation();
  try {
    # Accesses the first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Creates the default chart
    $chart = $slide->getShapes()->addChart(ChartType::ScatterWithSmoothLines, 0, 0, 400, 400);
    # Gets the default chart data worksheet index
    $defaultWorksheetIndex = 0;
    # Gets the chart data worksheet
    $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
    $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);
    $pres->save("AsposeChart_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $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.

  1. Create an instance of the Presentation class.
  2. Get a reference to a slide using its index.
  3. Add a chart with default data and specify the ChartType::Pie type.
  4. Access the chart data workbook ChartDataWorkbook.
  5. Clear the default series and categories.
  6. Add new series and categories.
  7. Add new chart data for the chart series.
  8. Add new points for the chart and apply custom colors for the pie chart’s sectors.
  9. Set labels for the series.
  10. Enable leader lines for the series labels.
  11. Set the rotation angle for pie chart sectors.
  12. Save the modified presentation as a PPTX file.

This PHP code shows how to create a pie chart:

  # Instantiates a presentation class that represents a PPTX file
  $pres = new Presentation();
  try {
    # Accesses the first slide
    $slides = $pres->getSlides()->get_Item(0);
    # Adds a chart with default data
    $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 first series to show values
    $chart->getChartData()->getSeries()->get_Item(0)->getLabels()->getDefaultDataLabelFormat()->setShowValue(true);
    # Sets the index for the chart data sheet
    $defaultWorksheetIndex = 0;
    # Gets the chart data worksheet
    $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
    $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);
    $point = $series->getDataPoints()->get_Item(0);
    $point->getFormat()->getFill()->setFillType(FillType::Solid);
    $point->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->CYAN);
    # Sets the Sector border
    $point->getFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $point->getFormat()->getLine()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->GRAY);
    $point->getFormat()->getLine()->setWidth(3.0);
    $point->getFormat()->getLine()->setStyle(LineStyle->ThinThick);
    $point->getFormat()->getLine()->setDashStyle(LineDashStyle->DashDot);
    $point1 = $series->getDataPoints()->get_Item(1);
    $point1->getFormat()->getFill()->setFillType(FillType::Solid);
    $point1->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->ORANGE);
    # Sets the Sector border
    $point1->getFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $point1->getFormat()->getLine()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->BLUE);
    $point1->getFormat()->getLine()->setWidth(3.0);
    $point1->getFormat()->getLine()->setStyle(LineStyle->Single);
    $point1->getFormat()->getLine()->setDashStyle(LineDashStyle->LargeDashDot);
    $point2 = $series->getDataPoints()->get_Item(2);
    $point2->getFormat()->getFill()->setFillType(FillType::Solid);
    $point2->getFormat()->getFill()->getSolidFillColor()->setColor(java("java.awt.Color")->YELLOW);
    # Sets the Sector border
    $point2->getFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $point2->getFormat()->getLine()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.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
    $lbl1 = $series->getDataPoints()->get_Item(0)->getLabel();
    # lbl.ShowCategoryName = true;
    $lbl1->getDataLabelFormat()->setShowValue(true);
    $lbl2 = $series->getDataPoints()->get_Item(1)->getLabel();
    $lbl2->getDataLabelFormat()->setShowValue(true);
    $lbl2->getDataLabelFormat()->setShowLegendKey(true);
    $lbl2->getDataLabelFormat()->setShowPercentage(true);
    $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
    $pres->save("PieChart_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Create Line Charts

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

  1. Create an instance of the Presentation class.
  2. Get a reference to a slide using its index.
  3. Add a chart with default data and specify the ChartType::Line type.
  4. Access the chart data workbook (ChartDataWorkbook).
  5. Clear the default series and categories.
  6. Add new series and categories.
  7. Add new chart data for the chart series.
  8. Save the modified presentation as a PPTX file.

This PHP code shows how to create a line chart:

  $pres = new Presentation();
  try {
    $lineChart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Line, 10, 50, 600, 350);
    $pres->save("lineChart.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

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

  $pres = new Presentation();
  try {
    $lineChart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Line, 10, 50, 600, 350);
    $seriesCollection = $lineChart->getChartData()->getSeries();
    foreach ($seriesCollection as $series) {
      $series->getFormat()->getLine()->setDashStyle(LineDashStyle::Dash);
    }
    $pres->save("lineChart.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $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 quickly draw attention to items that are large contributors within each category.

  1. Create an instance of the Presentation class.
  2. Get a reference to a slide using its index.
  3. Add a chart with default data and specify the ChartType::Treemap type.
  4. Access the chart data workbook ChartDataWorkbook.
  5. Clear the default series and categories.
  6. Add new series and categories.
  7. Add new chart data for the chart series.
  8. Save the modified presentation as a PPTX file.

This PHP code shows how to create a tree map chart:

  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::Treemap, 50, 50, 500, 400);
    $chart->getChartData()->getCategories()->clear();
    $chart->getChartData()->getSeries()->clear();
    $wb = $chart->getChartData()->getChartDataWorkbook();
    $wb->clear(0);
    # branch 1
    $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"));
    # branch 2
    $leaf = $chart->getChartData()->getCategories()->add($wb->getCell(0, "C5", "Leaf5"));
    $leaf->getGroupingLevels()->setGroupingItem(1, "Stem3");
    $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"));
    $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);
    $pres->save("Treemap.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

  2. Get a reference to a slide using its index.
  3. Add a chart with default data and specify the ChartType::OpenHighLowClose type.
  4. Access the chart data workbook ChartDataWorkbook.
  5. Clear the default series and categories.
  6. Add new series and categories.
  7. Add new chart data for the chart series.
  8. Specify the high-low lines format.
  9. Save the modified presentation as a PPTX file.

This PHP code shows how to create a stock chart:

  $pres = new Presentation();
  try {
    $chart = $pres->getSlides()->get_Item(0)->getShapes()->addChart(ChartType::OpenHighLowClose, 50, 50, 600, 400, false);
    $chart->getChartData()->getSeries()->clear();
    $chart->getChartData()->getCategories()->clear();
    $wb = $chart->getChartData()->getChartDataWorkbook();
    $chart->getChartData()->getCategories()->add($wb->getCell(0, 1, 0, "A"));
    $chart->getChartData()->getCategories()->add($wb->getCell(0, 2, 0, "B"));
    $chart->getChartData()->getCategories()->add($wb->getCell(0, 3, 0, "C"));
    $chart->getChartData()->getSeries()->add($wb->getCell(0, 0, 1, "Open"), $chart->getType());
    $chart->getChartData()->getSeries()->add($wb->getCell(0, 0, 2, "High"), $chart->getType());
    $chart->getChartData()->getSeries()->add($wb->getCell(0, 0, 3, "Low"), $chart->getType());
    $chart->getChartData()->getSeries()->add($wb->getCell(0, 0, 4, "Close"), $chart->getType());
    $series = $chart->getChartData()->getSeries()->get_Item(0);
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 1, 1, 72));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 2, 1, 25));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 3, 1, 38));
    $series = $chart->getChartData()->getSeries()->get_Item(1);
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 1, 2, 172));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 2, 2, 57));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 3, 2, 57));
    $series = $chart->getChartData()->getSeries()->get_Item(2);
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 1, 3, 12));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 2, 3, 12));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 3, 3, 13));
    $series = $chart->getChartData()->getSeries()->get_Item(3);
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 1, 4, 25));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 2, 4, 38));
    $series->getDataPoints()->addDataPointForStockSeries($wb->getCell(0, 3, 4, 50));
    $chart->getChartData()->getSeriesGroups()->get_Item(0)->getUpDownBars()->setUpDownBars(true);
    $chart->getChartData()->getSeriesGroups()->get_Item(0)->getHiLowLinesFormat()->getLine()->getFillFormat()->setFillType(FillType::Solid);
    $seriesCollection = $chart->getChartData()->getSeries();
    foreach ($seriesCollection as $ser) {
      $ser->getFormat()->getLine()->getFillFormat()->setFillType(FillType::NoFill);
    }
    $pres->save("output.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

  5. Modify the chart data series by changing the series values.
  6. Add a new series and populate its data.
  7. Save the modified presentation as a PPTX file.

This PHP code shows how to update a chart:

  $pres = new Presentation();
  try {
    # Access first slideMarker
    $sld = $pres->getSlides()->get_Item(0);
    # Get chart with default data
    $chart = $sld->getShapes()->get_Item(0);
    # Setting the index of chart data sheet
    $defaultWorksheetIndex = 0;
    # Getting the chart data worksheet
    $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
    $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));

    # Save presentation with chart
    $pres->save("AsposeChartModified_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Data Range for a Chart

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

  1. Create an instance of the Presentation class that represents the presentation containing the chart.

    $chart->getChartData()->getCategories()->clear();
    $fact = $chart->getChartData()->getChartDataWorkbook();
    $chart->getChartData()->getSeries()->add($fact->getCell(0, 0, 1, "Series 1"), $chart->getType());
    $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));
