3D Chart

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)
