I get strange "histogram-like" plots if the y-axes scale is some orders of magnitude smaller than the x-axis (latest svn version).
In [43]: matplotlib.__version__
Out[43]: '0.88svn'
# bad
x = arange(0,10,.1); y = sin(x)/100.0; plot(x,y); savefig('small_y.eps')
# good
x = arange(0,10,.1); y = sin(x); plot(x,y); savefig('normal_y.eps')
This doesn't happen if I export as .png
normal_y.eps (141 KB)
small_y.eps (141 KB)
