面对使用SetSourceData方法在python中通过Powerpoint绘制图表的问题

Question

我们编写了一些代码，以将Powerpoint演示文稿中的图表数据更新为现有图表。为了更新图表数据，我们调用方法“ .SetSourceData（Source =）”。 但是，通过说：

'pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147467259), None)'

需要尽快解决该问题。

当我调用chart.SetSourceData方法时出现以下错误 pywintypes.com_error：(-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147467259), None)
