使用 Python 將 PowerPoint 圖表和圖表添加到 PPTX

構建您自己的 Python 應用程序,以使用服務器端 API 在演示文稿文件中創建完全可定制的圖表。了解如何向圖表添加新系列和類別。

通過 Python 將餅圖添加到 PPTX 演示文稿

餅圖用於顯示數據中部分與整體的關係,尤其是當數據包含帶有數值的分類標籤時。 Aspose.Slides for Python via .NET 提供了一個強大的 API,用於在 PowerPoint 演示文稿中創建餅圖。您可以在此 鏈接 中找到有關使用 Aspose.Slides for Python API 自定義餅圖的更多信息。

以下代碼示例顯示瞭如何在 Python 中的 PowerPoint PPTX 中創建餅圖。


import aspose.slides as slides
import aspose.pydrawing as drawing

with slides.Presentation() as presentation:

    # Access first slide
    slide = presentation.slides[0]

    chart = slide.shapes.add_chart(slides.charts.ChartType.PIE, 100, 100, 400, 400)

    # Set chart title

如何通過 Python 在 PPTX 中創建和自定義餅圖

這些是將餅圖添加到 PPTX 文件的步驟。

  1. 首先,創建 PPTX Presentation 類的一個實例。

  2. 使用 add_chart(…) 方法添加一個帶有默認數據的餅圖。

  3. 配置餅圖的必要屬性(設置圖表標題,修改圖表數據,將格式應用於系列和類別)

  4. 以 PPTX 格式保存結果
