yup -- though it's an understandable miss...

you are increasing the resolution of the figure, and of your 
calculations, but NOT of the output image. The hint was that every image 
was the same size: 1200X900 , which is 12"x9" at 100 dpi.

It turns out that print_figure() doesn't respect the figures (native 
DPI), it defaults to 100 dpi, but you can override it:

 > canvas.print_figure("test"+str(DPI)+"dpi.png", dpi=DPI)

Then you'll get what I think you want.

Maybe this will help:

http://www.scipy.org/Cookbook/Matplotlib/AdjustingImageSize

though it there, I talked about Figure.savefig(). I don't know if there 
is a difference between that and Figure.print_figure()
