[Matplotlib-users] Interactively get readable(i.e. lng/lat) coordinates from a matplotlib basemap plot?

[Jonathan_Kowalik <jon...@na...>]

Hi.
I also asked this question on stackoverflow, but I think it might even
better to ask it here.
I'm doing basemap plots. The current coordinates of the mouse pointer are
interactively displayed in the lower right area of the figure. But they are
in map coordinates (I assume). I would like to have them in lng/lat.

Is there a quick way to do this?
Do I have to dive into mouse events (which I'm not familiar with yet)?

Thanks!
Jonathan

I already got the answer:

    ax = plt.gca()
    def format_coord(x, y):
        return 'x=%.4f, y=%.4f'%(m(x, y, inverse = True))
    ax.format_coord = format_coord

This does exactly what I wanted. :-)
