python - wxPython Plot overlapping -

i designing gui , got problem configuration of plots. won't post whole script because hundreds of lines long. show problem , specific code segment:

so see ugly grey block polar plot. don't know how remove it, or make small possible.

i need display multiple plot on 1 page.

another minor problem {0.2,0.4,0.6,0.8,1.0} axis values polar plot.

here comes script extract, hope can me.
