如何切换下面标记为红色的参数(英文:python pptx 中的“showcategories”以显示饼图?任何想法表示赞赏。
最佳答案
显然有一个功能请求:https://github.com/scanny/python-pptx/issues/242
同时,可以通过从 python 设置标签文本来解决此问题,例如如下所示:
from pptx import Presentation
from pptx.chart.data import ChartData
from pptx.enum.chart import XL_CHART_TYPE, XL_LABEL_POSITION
from pptx.util import Inches
# create presentation with 1 slide ------
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])
chart_data = ChartData()
chart_data.categories = ['West', 'East', 'North', 'South', 'Other']
chart_data.add_series('Series 1', (0.135, 0.324, 0.180, 0.235, 0.126))
x, y, cx, cy = Inches(2), Inches(2), Inches(6), Inches(4.5)
chart = slide.shapes.add_chart(
XL_CHART_TYPE.PIE, x, y, cx, cy, chart_data
).chart
chart.has_legend = False
# set labels to contain category and value
for i in range(len(chart_data.categories)):
point = chart.series[0].points[i]
point.data_label.text_frame.text = "{}: {:.0%}".format(chart_data.categories[i].label, chart.series[0].values[i])
point.data_label.position = XL_LABEL_POSITION.OUTSIDE_END
prs.save('chart-01.pptx')
