Customize 3D Charts in Presentations with Python

Set RotationX, RotationY and DepthPercents properties of 3D Chart

Aspose.Slides for Python via .NET provides a simple API for setting these properties. This following article will help you how set different properties like X,Y Rotation , DepthPercents etc. The sample code applies setting the above said properties.

1. Create an instance of the Presentation class.
2. Access first slide.
3. Add chart with default data.
4. Set Rotation3D properties.
5. Write the modified presentation to a PPTX file.

import aspose.slides.charts as charts
import aspose.slides as slides
import aspose.pydrawing as draw

# Create an instance of Presentation class
with slides.Presentation() as presentation:
            
    # Access first slide
    slide = presentation.slides[0]

    # Add chart with default data
    chart = slide.shapes.add_chart(charts.ChartType.STACKED_COLUMN_3D, 0, 0, 500, 500)

    # Setting the index of chart data sheet
    defaultWorksheetIndex = 0

    # Getting the chart data worksheet
    fact = chart.chart_data.chart_data_workbook

    # Add series
    chart.chart_data.series.add(fact.get_cell(defaultWorksheetIndex, 0, 1, "Series 1"), chart.type)
    chart.chart_data.series.add(fact.get_cell(defaultWorksheetIndex, 0, 2, "Series 2"), chart.type)

    # Add Catrgories
    chart.chart_data.categories.add(fact.get_cell(defaultWorksheetIndex, 1, 0, "Caetegoty 1"))
    chart.chart_data.categories.add(fact.get_cell(defaultWorksheetIndex, 2, 0, "Caetegoty 2"))
    chart.chart_data.categories.add(fact.get_cell(defaultWorksheetIndex, 3, 0, "Caetegoty 3"))

    # Set Rotation3D properties
    chart.rotation_3d.right_angle_axes = True
    chart.rotation_3d.rotation_x = 40
    chart.rotation_3d.rotation_y = 270
    chart.rotation_3d.depth_percents = 150

    # Take second chart series
    series = chart.chart_data.series[1]

    # Now populating series data
    series.data_points.add_data_point_for_bar_series(fact.get_cell(defaultWorksheetIndex, 1, 1, 20))
    series.data_points.add_data_point_for_bar_series(fact.get_cell(defaultWorksheetIndex, 2, 1, 50))
    series.data_points.add_data_point_for_bar_series(fact.get_cell(defaultWorksheetIndex, 3, 1, 30))
    series.data_points.add_data_point_for_bar_series(fact.get_cell(defaultWorksheetIndex, 1, 2, 30))
    series.data_points.add_data_point_for_bar_series(fact.get_cell(defaultWorksheetIndex, 2, 2, 10))
    series.data_points.add_data_point_for_bar_series(fact.get_cell(defaultWorksheetIndex, 3, 2, 60))

    # Set OverLap value
    series.parent_series_group.overlap = 100         

    # Write presentation to disk
    presentation.save("Rotation3D_out.pptx", slides.export.SaveFormat.PPTX)

FAQ

Which chart types support 3D mode in Aspose.Slides?

Aspose.Slides supports 3D variants of column charts, including Column 3D, Clustered Column 3D, Stacked Column 3D, and 100% Stacked Column 3D, along with related 3D types exposed through the ChartType enumeration. For an exact, up-to-date list, check the ChartType members in the API reference of your installed version.

Can I get a raster image of a 3D chart for a report or the web?

Yes. You can export a chart to an image via the chart API or render the entire slide to formats like PNG or JPEG. This is useful when you need a pixel-perfect preview or want to embed the chart into documents, dashboards, or web pages without requiring PowerPoint.

How performant is building and rendering large 3D charts?

Performance depends on data volume and visual complexity. For best results, keep 3D effects minimal, avoid heavy textures on walls and plot areas, limit the number of data points per series when possible, and render to an appropriately sized output (resolution and dimensions) to match the target display or print needs.
