I don't know if that has been reported yet, but the size of postscript output
doesn't change when "less" points are plotted.
x = range(8000)
y = [rand() for i in x]
produces rougly the same size eps file.
It seems that the PS backend draws outside the bounding box and then clips it.
Is there any solution/workaround for this? If you submit ps files to
publishers they often restrict the size of the files.
I am using mpl 0.82
