I'm creating a plot using matplotlib from a Pandas DataFrame like this:
我正在使用来自Pandas DataFrame的matplotlib创建一个情节，如下所示：

It seems like I should be doing it this way:
好像我应该这样做：

The problem is that dfbuild.plot returns an AxesSubplot and not a Figure instance, which is required by the savefig function.
问题是dfbuild.plot返回一个AxesSubplot而不是一个图实例，这是savefig函数所需要的。

这解决了这个问题：
pp.savefig(bplot.figure)

I works when I do it this way.
我这样做的时候会工作。
pp = PdfPages(r'c:\temp\page.pdf')
dfbuild.plot(x=['Build','Opperator'],kind='barh',stacked='True')
pp.savefig()
pp.close()
