Create or Update PowerPoint Presentation Charts in Python

What this page is about

Create and customize charts in PowerPoint presentations using Aspose.Slides for Python via Java. Add, format, and edit charts with practical code examples in Python.

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.

Note

To create charts, use the ChartType class. The fields in this class correspond to different chart types.

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:

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

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

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, FillType, NullableBool, Presentation, SaveFormat

Color = jpype.JClass("java.awt.Color")

# Instantiates a presentation class that represents a PPTX file.
presentation = Presentation()
try:
    # Accesses the first slide
    slide = presentation.getSlides().get_Item(0)

    # Adds a chart with its default data
    chart = slide.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
    default_worksheet_index = 0

    # Gets the chart data WorkSheet
    workbook = chart.getChartData().getChartDataWorkbook()

    # Deletes the default generated series and categories
    chart.getChartData().getSeries().clear()
    chart.getChartData().getCategories().clear()

    # Adds new series
    cell = workbook.getCell(default_worksheet_index, 0, 1, "Series 1")
    chart.getChartData().getSeries().add(cell,chart.getType())
    cell = workbook.getCell(default_worksheet_index, 0, 2, "Series 2")
    chart.getChartData().getSeries().add(cell,chart.getType())

    # Adds new categories
    cell = workbook.getCell(default_worksheet_index, 1, 0, "Category 1")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(default_worksheet_index, 2, 0, "Category 2")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(default_worksheet_index, 3, 0, "Category 3")
    chart.getChartData().getCategories().add(cell)

    # Takes the first chart series
    series = chart.getChartData().getSeries().get_Item(0)

    # Now populates the series data
    cell = workbook.getCell(default_worksheet_index, 1, 1, 20)
    series.getDataPoints().addDataPointForBarSeries(cell)
    cell = workbook.getCell(default_worksheet_index, 2, 1, 50)
    series.getDataPoints().addDataPointForBarSeries(cell)
    cell = workbook.getCell(default_worksheet_index, 3, 1, 30)
    series.getDataPoints().addDataPointForBarSeries(cell)

    # 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
    cell = workbook.getCell(default_worksheet_index, 1, 2, 30)
    series.getDataPoints().addDataPointForBarSeries(cell)
    cell = workbook.getCell(default_worksheet_index, 2, 2, 10)
    series.getDataPoints().addDataPointForBarSeries(cell)
    cell = workbook.getCell(default_worksheet_index, 3, 2, 60)
    series.getDataPoints().addDataPointForBarSeries(cell)

    # 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
    label = series.getDataPoints().get_Item(0).getLabel()
    label.getDataLabelFormat().setShowCategoryName(True)

    label = series.getDataPoints().get_Item(1).getLabel()
    label.getDataLabelFormat().setShowSeriesName(True)

    # Shows value for the third label
    label = series.getDataPoints().get_Item(2).getLabel()
    label.getDataLabelFormat().setShowValue(True)
    label.getDataLabelFormat().setShowSeriesName(True)
    label.getDataLabelFormat().setSeparator("/")

    # Saves the presentation with chart
    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.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

Follow the steps in Create Clustered Column Charts.
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 Python code shows how to create a scatter chart with different markers for each series:

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, MarkerStyleType, Presentation, SaveFormat

# Instantiates a presentation class that represents a PPTX file.
presentation = Presentation()
try:
    # Accesses the first slide
    slide = presentation.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
    default_worksheet_index = 0

    # Gets the chart data worksheet
    workbook = chart.getChartData().getChartDataWorkbook()

    # Deletes the demo series
    chart.getChartData().getSeries().clear()

    # Adds new series
    cell = workbook.getCell(default_worksheet_index, 1, 1, "Series 1")
    chart.getChartData().getSeries().add(cell, chart.getType())
    cell = workbook.getCell(default_worksheet_index, 1, 3, "Series 2")
    chart.getChartData().getSeries().add(cell, chart.getType())

    # Takes first chart series
    series = chart.getChartData().getSeries().get_Item(0)

    # Adds a new point (1:3) to the series
    x_cell = workbook.getCell(default_worksheet_index, 2, 1, 1)
    y_cell = workbook.getCell(default_worksheet_index, 2, 2, 3)
    series.getDataPoints().addDataPointForScatterSeries(x_cell, y_cell)

    # Adds a new point (2:10)
    x_cell = workbook.getCell(default_worksheet_index, 3, 1, 2)
    y_cell = workbook.getCell(default_worksheet_index, 3, 2, 10)
    series.getDataPoints().addDataPointForScatterSeries(x_cell, y_cell)

    # 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
    x_cell = workbook.getCell(default_worksheet_index, 2, 3, 5)
    y_cell = workbook.getCell(default_worksheet_index, 2, 4, 2)
    series.getDataPoints().addDataPointForScatterSeries(x_cell, y_cell)

    # Adds a new point (3:1)
    x_cell = workbook.getCell(default_worksheet_index, 3, 3, 3)
    y_cell = workbook.getCell(default_worksheet_index, 3, 4, 1)
    series.getDataPoints().addDataPointForScatterSeries(x_cell, y_cell)

    # Adds a new point (2:2)
    x_cell = workbook.getCell(default_worksheet_index, 4, 3, 2)
    y_cell = workbook.getCell(default_worksheet_index, 4, 4, 2)
    series.getDataPoints().addDataPointForScatterSeries(x_cell, y_cell)

    # Adds a new point (5:1)
    x_cell = workbook.getCell(default_worksheet_index, 5, 3, 5)
    y_cell = workbook.getCell(default_worksheet_index, 5, 4, 1)
    series.getDataPoints().addDataPointForScatterSeries(x_cell, y_cell)

    # Changes the chart series marker
    series.getMarker().setSize(10)
    series.getMarker().setSymbol(MarkerStyleType.Circle)

    presentation.save("AsposeChart_out.pptx", SaveFormat.Pptx)
finally:
    presentation.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.

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

This Python code shows how to create a pie chart:

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, FillType, LineDashStyle, LineStyle, NullableBool, Presentation, SaveFormat

    # Adds a chart with default data
    chart = slide.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
    default_worksheet_index = 0

    # Gets the chart data worksheet
    workbook = chart.getChartData().getChartDataWorkbook()

    # Deletes the default generated series and categories
    chart.getChartData().getSeries().clear()
    chart.getChartData().getCategories().clear()

    # Adds new categories
    cell = workbook.getCell(0, 1, 0, "First Qtr")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(0, 2, 0, "2nd Qtr")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(0, 3, 0, "3rd Qtr")
    chart.getChartData().getCategories().add(cell)

    # Adds new series
    cell = workbook.getCell(0, 0, 1, "Series 1")
    series = chart.getChartData().getSeries().add(cell, chart.getType())

    #Populates the series data

    cell = workbook.getCell(default_worksheet_index, 3, 1, 30)
    series.getDataPoints().addDataPointForPieSeries(cell)

    # Adding new points and setting sector color
    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(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)

    second_point = series.getDataPoints().get_Item(1)
    second_point.getFormat().getFill().setFillType(FillType.Solid)
    second_point.getFormat().getFill().getSolidFillColor().setColor(Color.ORANGE)

    # Sets the Sector border
    second_point.getFormat().getLine().getFillFormat().setFillType(FillType.Solid)
    second_point.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(Color.BLUE)
    second_point.getFormat().getLine().setWidth(3.0)
    second_point.getFormat().getLine().setStyle(LineStyle.Single)

    third_point.getFormat().getFill().setFillType(FillType.Solid)
    third_point.getFormat().getFill().getSolidFillColor().setColor(Color.YELLOW)

    # Sets the Sector border

    third_point.getFormat().getLine().setWidth(2.0)
    third_point.getFormat().getLine().setStyle(LineStyle.ThinThin)
    third_point.getFormat().getLine().setDashStyle(LineDashStyle.LargeDashDotDot)

    # Creates custom labels for each of categories for new series

    presentation.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.

Create an instance of the Presentation class.
Get a reference to a slide using its index.
Add a chart with default data and specify the ChartType.Line type.
Save the modified presentation as a PPTX file.

This Python code shows how to create a line chart:

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, Presentation, SaveFormat

presentation = Presentation()
try:
    line_chart = presentation.getSlides().get_Item(0).getShapes().addChart(ChartType.Line, 10, 50, 600, 350)

    presentation.save("line_chart.pptx", SaveFormat.Pptx)
finally:
    presentation.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:

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, LineDashStyle, Presentation, SaveFormat

presentation = Presentation()
try:
    line_chart = presentation.getSlides().get_Item(0).getShapes().addChart(ChartType.Line, 10, 50, 600, 350)

    for series in line_chart.getChartData().getSeries():
        series.getFormat().getLine().setDashStyle(LineDashStyle.Dash)

    presentation.save("line_chart.pptx", SaveFormat.Pptx)
finally:
    presentation.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.

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

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

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, ParentLabelLayoutType, Presentation, SaveFormat

presentation = Presentation()
try:
    chart = presentation.getSlides().get_Item(0).getShapes().addChart(ChartType.Treemap, 50, 50, 500, 400)
    chart.getChartData().getCategories().clear()
    chart.getChartData().getSeries().clear()

    workbook = chart.getChartData().getChartDataWorkbook()
    workbook.clear(0)

    #branch 1
    cell = workbook.getCell(0, "C1", "Leaf1")
    leaf = chart.getChartData().getCategories().add(cell)
    leaf.getGroupingLevels().setGroupingItem(1, "Stem1")
    leaf.getGroupingLevels().setGroupingItem(2, "Branch1")

    cell = workbook.getCell(0, "C2", "Leaf2")
    chart.getChartData().getCategories().add(cell)

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

    cell = workbook.getCell(0, "C4", "Leaf4")
    chart.getChartData().getCategories().add(cell)

    #branch 2
    cell = workbook.getCell(0, "C5", "Leaf5")
    leaf = chart.getChartData().getCategories().add(cell)
    leaf.getGroupingLevels().setGroupingItem(1, "Stem3")
    leaf.getGroupingLevels().setGroupingItem(2, "Branch2")

    cell = workbook.getCell(0, "C6", "Leaf6")
    chart.getChartData().getCategories().add(cell)

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

    cell = workbook.getCell(0, "C8", "Leaf8")
    chart.getChartData().getCategories().add(cell)

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

    series.setParentLabelLayout(ParentLabelLayoutType.Overlapping)

    presentation.save("Treemap.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

    series.getDataPoints().addDataPointForBarSeries(cell)
    cell = workbook.getCell(default_worksheet_index, 3, 3, 30)
    series.getDataPoints().addDataPointForBarSeries(cell)

Set Data Range for a Chart

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

Create an instance of the Presentation class that represents the presentation containing the chart.
Get a reference to a slide using its index.
Traverse through all shapes to find the desired chart.
Access the chart data and set the range.
Save the modified presentation as a PPTX file.

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

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat

# Opens the presentation that contains the chart
presentation = Presentation("ExistingChart.pptx")
try:
    slide = presentation.getSlides().get_Item(0)
    chart = slide.getShapes().get_Item(0)

    chart.getChartData().setRange("Sheet1!A1:B4")

    presentation.save("SetDataRange_out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Use Default Markers in Charts

When you use default markers in charts, each chart series automatically gets a different marker symbol.

This Python code shows how to set a chart series marker automatically:

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    chart = slide.getShapes().addChart(ChartType.LineWithMarkers, 10, 10, 400, 400)

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

    workbook = chart.getChartData().getChartDataWorkbook()
    cell = workbook.getCell(0, 0, 1, "Series 1")
    chart.getChartData().getSeries().add(cell, chart.getType())
    series = chart.getChartData().getSeries().get_Item(0)

    cell = workbook.getCell(0, 1, 0, "C1")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(0, 1, 1, 24)
    series.getDataPoints().addDataPointForLineSeries(cell)
    cell = workbook.getCell(0, 2, 0, "C2")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(0, 2, 1, 23)
    series.getDataPoints().addDataPointForLineSeries(cell)
    cell = workbook.getCell(0, 3, 0, "C3")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(0, 3, 1, -10)
    series.getDataPoints().addDataPointForLineSeries(cell)
    cell = workbook.getCell(0, 4, 0, "C4")
    chart.getChartData().getCategories().add(cell)
    cell = workbook.getCell(0, 4, 1, None)
    series.getDataPoints().addDataPointForLineSeries(cell)

    cell = workbook.getCell(0, 0, 2, "Series 2")
    chart.getChartData().getSeries().add(cell, chart.getType())
    #Take second chart series
    second_series = chart.getChartData().getSeries().get_Item(1)

    #Now populating series data
    cell = workbook.getCell(0, 1, 2, 30)
    second_series.getDataPoints().addDataPointForLineSeries(cell)
    cell = workbook.getCell(0, 2, 2, 10)
    second_series.getDataPoints().addDataPointForLineSeries(cell)
    cell = workbook.getCell(0, 3, 2, 60)
    second_series.getDataPoints().addDataPointForLineSeries(cell)
    cell = workbook.getCell(0, 4, 2, 40)
    second_series.getDataPoints().addDataPointForLineSeries(cell)

    chart.setLegend(True)
    chart.getLegend().setOverlay(False)

    presentation.save("DefaultMarkersInChart.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
