get_axes not present?

>And what is the result of plot()?  Is it a valid object, or is it None?

Well the error happens on the plot() line. I tried to print some information like this:


    print("axes=", axes)
    print("axes[0]=", axes[0])
    print("cnt=", cnt)
    print("row=", row)
    ax1 = row.plot( fontsize=font_size, linewidth=line_width, markersize=marker_size, marker='o', title='Raw values', label=cnt, ax=axes[0] )



The output looks like


axes= [<AxesSubplot:> <AxesSubplot:>]
axes[0]= AxesSubplot(0.125,0.53;0.775x0.35)
cnt= 1
row= 1       278528
2       278528
3       278528
4       278528
5       278528
         ...
5604    278528
5605    278528
5606    278528
5607    278528

    ax for ax in self.axes[0].get_figure().get_axes() if isinstance(ax, Subplot)
AttributeError: 'NoneType' object has no attribute 'get_axes'



The error is weird. I have stick at this error...
Any thoughts on that?
