Is there anything wrong with my code? I used 3 sizers in 1 boxsizer in main frame. The bottom sizer is used for plotting and the other two are used for user interaction. The most important problem lies in too much blank area exists between 3 sizers now. I want my GUI looks more compact and the plot area should be largers if possible.

I changed two lines of code, and think it might be what you are looking for.
