Another question

Dear ALL,

Another (this time possibly quite silly) question: how can I make a
Basemap cover entirely the display area of the GUI backend (ie.,
without the top, bottom, left, right spaces)?

I tried something like:

self.figure = Figure()
self.figure.subplots_adjust(left=-0.01, bottom=-0.750, right=1.0, top=1.55)

but could not control the bottom (or top) margins.

Thanks in advance for any hints.

Best regards,

···

The reason is that a map has a fixed aspect ratio, and there is no mechanism for automatically shrinking the appropriate figure dimension to eliminate extra space. You will have adjust the figure dimensions manually.

Dear Eric,

Thanks for your reply. This is surely not good news -- maybe an
automatic shrinking mechanism could be added in a future version of
Matplotlib (this would be useful not only with maps, but with other
plots as well)?

Best regards,

Mauro: You'll have to create a figure with the same aspect ratio as the map, and then add an axes to the figure that fills the entire figure (i.e. fig.add_axes([0,0,1,1]). The `aspect` Basemap instance variable tells you the aspect ratio of the map. For instance, in the wx embedding example you sent me, the map.aspect = 0.5. Therefore, you would need to create a figure canvas that is twice as wide as it is high, like this

self.figure = Figure(figsize=(10,5))

then add an axes instances that fills the figure completely

self.ax = self.figure.add_axes([0,0,1,1])

Note that you will not have any room for labels if you do this.

HTH,
