## Create a Pie Chart in a PPTX Presentation with Python

[Aspose.Slides for Python via .NET](/slides/python-net/) lets you create a pie chart, replace its default categories and series, and customize its labels and colors. Pie charts work best when showing how a small number of numeric categories contribute to a whole. For more options, see [Customize Pie Charts in Presentations](https://docs.aspose.com/slides/python-net/pie-chart/).

### Create a Pie Chart in a PPTX Presentation with Python

```python
with slides.Presentation() as presentation:
    slide = presentation.slides[0]
    chart = slide.shapes.add_chart(slides.charts.ChartType.PIE, 100, 100, 400, 400)

    chart.has_title = True
    chart.chart_title.add_text_frame_for_overriding("Quarterly Sales")
    chart.chart_title.height = 20

    worksheet_index = 0
    workbook = chart.chart_data.chart_data_workbook
    chart.chart_data.series.clear()
    chart.chart_data.categories.clear()

    categories = ("First Quarter", "Second Quarter", "Third Quarter")
    values = (20, 50, 30)

    for row_index, category in enumerate(categories, start=1):
        category_cell = workbook.get_cell(worksheet_index, row_index, 0, category)
        chart.chart_data.categories.add(category_cell)

    series_name_cell = workbook.get_cell(worksheet_index, 0, 1, "Sales")
    series = chart.chart_data.series.add(series_name_cell, chart.type)

    for row_index, value in enumerate(values, start=1):
        value_cell = workbook.get_cell(worksheet_index, row_index, 1, value)
        series.data_points.add_data_point_for_pie_series(value_cell)

    series.labels.default_data_label_format.show_percentage = True
    series.parent_series_group.is_color_varied = True
    series.parent_series_group.first_slice_angle = 180

    fill_colors = (drawing.Color.orange, drawing.Color.blue_violet, drawing.Color.yellow_green)

    for data_point_index, fill_color in enumerate(fill_colors):
        data_point = series.data_points[data_point_index]
        data_point.format.fill.fill_type = slides.FillType.SOLID
        data_point.format.fill.solid_fill_color.color = fill_color

    presentation.save("pie-chart.pptx", slides.export.SaveFormat.PPTX)
```

## How to Create and Customize a Pie Chart in PPTX with Python

Follow these steps to add a pie chart to a PPTX presentation.

Create a `Presentation` instance and access the desired slide through a `slide` variable.

Call `add_chart` with `ChartType.PIE` to add a pie chart to the slide.

Use `chart_data_workbook` to replace the default categories and series, then configure the labels, colors, and `first_slice_angle`.

Call `save` with `SaveFormat.PPTX` to write the presentation in PPTX format.
