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 On Tuesday 13 February 2007 13:21, Matthias Michler wrote: > Hello everbody, > > sometimes I need an autoscaling when my new data points in a figure have > small values compared to some deleted ones.
