I tried that, but that will make the entire plot look very strange if
xlim = [0;100] and ylim=[-1:1].
What I really want to do is add a scale free aspect ratio correct circle
to the plot. Just like the circles that appear on a scatter plot.
Best regards,
Mads

Hi Mads,
Did you add axis='equal' to you axes command?
e.g. ax = fig.add_subplot(111, aspect='equal')

Hi,
I am using the Qt4 based back engine for displaying a 2D plot in a
widget. The plot typically contains lots of line plots. Suppose I
add a
CirclePolygon to the plot like this:
circle = CirclePolygon((x,y), radius=0.04, edgecolor='black',
facecolor='red', zorder=1)
axes.add_patch(circle)
Then when I start to zoom in the window the aspect ratio of the circle
is not preserved (it appears like an ellipse). If you plot a line with
points, displaying its points using circles, these circles do have
their
aspect ratio (and size) preserved. There must be some approach for
achieving the same effect for a manually added circle.
Any help is appreciated,
Best regards,
Mads
