Chart

What this page is about

Create, access, remove, and update charts in PowerPoint and OpenDocument presentations with Aspose.Slides for Python via Java.

This article demonstrates how to add, access, remove, and update charts in a presentation using Aspose.Slides for Python via Java.

Install the package as described in Installation. Each example imports asposeslides before starting the JVM, then imports the API after the JVM is running. Run the addition example first to create chart.pptx for the remaining examples.

Add a Chart

Add an area chart to the first slide and save the presentation.

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)

    # Add an area chart to the first slide.
    chart = slide.getShapes().addChart(ChartType.Area, 50, 50, 400, 300)

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

Access a Chart

Find the first chart in the shape collection on the first slide.

import jpype
import asposeslides

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

from asposeslides.api import Chart, Presentation

presentation = Presentation("chart.pptx")
try:
    slide = presentation.getSlides().get_Item(0)

    # Access the first chart on the slide.
    first_chart = None
    for index in range(slide.getShapes().size()):
        shape = slide.getShapes().get_Item(index)
        if isinstance(shape, Chart):
            first_chart = shape
            break

    if first_chart is None:
        print("The first slide contains no charts.")
finally:
    presentation.dispose()

Remove a Chart

Remove the first chart from the slide and save the modified presentation.

import jpype
import asposeslides

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

from asposeslides.api import Chart, Presentation, SaveFormat

presentation = Presentation("chart.pptx")
try:
    slide = presentation.getSlides().get_Item(0)

    # Find and remove the first chart on the slide.
    chart = None
    for index in range(slide.getShapes().size()):
        shape = slide.getShapes().get_Item(index)
        if isinstance(shape, Chart):
            chart = shape
            break

    if chart is not None:
        slide.getShapes().remove(chart)
    else:
        print("The first slide contains no charts.")

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

Update Chart Data

Display the chart title, change its text, and save the updated presentation.

import jpype
import asposeslides

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

from asposeslides.api import Chart, Presentation, SaveFormat

presentation = Presentation("chart.pptx")
try:
    slide = presentation.getSlides().get_Item(0)

    # Find the first chart on the slide.
    chart = None
    for index in range(slide.getShapes().size()):
        shape = slide.getShapes().get_Item(index)
        if isinstance(shape, Chart):
            chart = shape
            break

    if chart is not None:
        # Display the chart title and change its text.
        chart.setTitle(True)
        chart.getChartTitle().addTextFrameForOverriding("Sales Report")
    else:
        print("The first slide contains no charts.")

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