使用python-pptx更改图表背景颜色

pip install python-pptx

from pptx import Presentation
from pptx.enum.chart import XL_CHART_TYPE
from pptx.dml.color import RGBColor

ppt = Presentation('your_presentation.pptx')
slide = ppt.slides[0]  # 假设要修改第一张幻灯片

for shape in slide.shapes:
    if shape.has_chart:
        chart = shape.chart
        if chart.chart_type in (XL_CHART_TYPE.COLUMN_CLUSTERED, XL_CHART_TYPE.BAR_CLUSTERED):
            chart.chart_area.fill.solid()  # 设置图表区域填充为纯色
            chart.chart_area.fill.fore_color.rgb = RGBColor(255, 0, 0)  # 设置背景颜色为红色

ppt.save('modified_presentation.pptx')
