That is really awesome, I wrote myself a little script today using the
poly_editor, data browser and the widgets. This is really cool.
I have one problem however, with the widgets I have buttons to switch
between different data sets and like in the button demo i just update the
plotdata rather than creating a new plot object. I then try to
ax.autoscale_view, but that doesnt do anything even after a
fig.canvas.draw() update. any ideas?
Cheers
Wolfgang
