[Matplotlib-users] viewport off-by-one error?

[Steve C. <ste...@ya...>]

John,
I noticed that when plotting sine waves (simple_plot.py for example)
with the gtk backend that the lowest points are not plotted.

So I wrote a test script to plot a square, the result is that the left
and top edges are plotted and the bottom and right edges are clipped off
(I can pan the view to display the missing lines). I can't think of any
reason why you would plot data points and then expect them to be clipped
off, so to me it looks like an off-by-one error.

Test program:

from matplotlib.matlab import *

figure(1)
x = arange(0, 10+1, 1)
plot(x,     x*0+10, 'r-',
     x,     x*0,    'r-',
     x*0,   x,      'r-',
     x*0+10, x,     'r-')

show()

Regards,
Steve
