I am trying to figure out the best way to create an inset axis on a
plot, but where one inset axis shares the same scale as the main axis.
Basically, I want something like the inset axes in axes_demo.py, but
where the x-axis of the inset axis is aligned and has the same scale
as the main x-axis i.e., rather than specifying the relative co-
ordinates of the inset axis in the figure, I want to specify the x
extents in the data units of the main axis. The y-scale will be
I though this might be related to "sharing" axes, but that is
something else. In a sense, I want the inset axes to be a "view" of
the larger axis.
I can do all this by calculating where the new axis should go, etc.
in figure units, but wondered if there was a "best practise" for
doing this so that I can guarantee that the inset axis will always be
aligned with the main figure axis, even if the figure is resized etc.
Also, are there standard functions for converting co-ordinates from
the data co-ordinates of the axes to relative figure co-ordinates
etc.? (I am sure the proper names for each co-ordinate system, and
the transformation etc. are described somewhere, but I have not found
Thanks for any suggestions or guidance.
