Question

这里刚刚进入Python并遇到了一个让我失望的问题。我有以下Python代码摘录，用于从现有模板创建PPT幻灯片。布局和占位符是正确的，但我无法使用下面列出的数据（x，y_in和＆amp; y_out）运行它。非常感谢任何帮助。

x = [datetime.datetime(2017, 8, 4, 15, 5, tzinfo=<FixedOffset u'+00:00' datetime.timedelta(0)>), datetime.datetime(2017, 8, 4, 15, 10, tzinfo=<FixedOffset u'+00:00' datetime.timedelta(0)>), datetime.datetime(2017, 8, 4, 15, 15, tzinfo=<FixedOffset u'+00:00' datetime.timedelta(0)>), datetime.datetime(2017, 8, 4, 15, 20, tzinfo=<FixedOffset u'+00:00' datetime.timedelta(0)>)]

y_in = [780993, 538962, 730180, 1135936]

y_out = [5631489, 6774738, 6485944, 6611580]

prs = Presentation('Network_Utilization_template_master.pptx')

slide = prs.slides.add_slide(prs.slide_layouts[2])  
placeholder = slide.placeholders[17]
chart_data = CategoryChartData()
chart_data.categories = x
chart_data.add_series(y_in)
chart_data.add_series(y_out)

graphic_frame = placeholder.insert_chart(XL_CHART_TYPE.LINE, chart_data)
chart = graphic_frame.chart
chart.has_legend = True
chart.legend.include_in_layout = True
chart.series[0-2].smooth = True

prs.save("Network_Utilization_" + today_s + ".pptx")

编译器吐出以下内容：

Traceback (most recent call last):

    data = data.replace("&", "&amp;")

Answer 1

David Zemens的评论非常正确。系列有一个名称，它显示为ChartData.add_series()的第一个参数。该名称显示在该系列的线条颜色旁边的图例中，也显示为该系列数据的列标题。添加它可以让你进入下一步。

类似的东西：

chart_data.add_series('MB in', y_in)
chart_data.add_series('MB out', y_out)
