Movable Legend

Community matplotlib-users

Hi All,

    a while ago, Che posted a nice example on how to drag a legend
with the mouse. I have upgraded to matplotlib 0.99.1 and it looks like
the nice example is not working anymore: for the life of me I can't
figure out what's wrong. I attach the runnable sample submitted
originally.

Any suggestion regarding what's wrong with the code?

Thank you in advance.

Andrea.

This is a known bug. While this is fixed in the svn, this did go into
the maint. branch.
As a workaround, add the following line after line 70.

        self.legend.set_axes(self.subplot)

Hi Jae-Joon,

This is a known bug. While this is fixed in the svn, this did go into
the maint. branch.
As a workaround, add the following line after line 70.

   self\.legend\.set\_axes\(self\.subplot\)

Thank you for your help, it works perfectly.

This movable legend is a good idea on plots, especially if there are many elements on one figure. However a few notes that I would like to add:

1-) So many lines of code. Makes it hard to read when I share the code with someone else. Would be so much better to have a functionality like:
plt.legend(movable=True). I might add this into the feature request page, if one hasn’t submitted yet.

2-) When I move the legend out of a canvas area, I can’t bring back into the canvas, nor move it any longer.

3-) The rest of the toolbox items are gone. How to zoom or pan when I have a moving legend?

Regards,
