Re: [Matplotlib-users] question about autoscale_view()

[Matthias M. <Mat...@gm...>]

Hi everybody,

some time ago I send the first mail concerning "pylab.autoscale_view()".
Unfortunately nobody reponsed - so I ask you again for any suggestions.
If I should set up another example or explain it, please let me know.

best regards and thanks in advance for any hint,
Matthias
