The matplotlib mpl_toolkits.axes_grid1 toolkit is a collection of
helper classes to ease displaying multiple images in matplotlib. While the
aspect parameter in matplotlib adjust the position of the single axes,
axesgrid1 toolkit provides a framework to adjust the position of
multiple axes according to their aspects.
Note
AxesGrid toolkit has been a part of matplotlib since v 0.99. Originally, the toolkit had a single namespace of axes_grid. In more recent version, the toolkit has divided into two separate namespace (axes_grid1 and axisartist). While axes_grid namespace is maintained for the backward compatibility, use of axes_grid1 and axisartist is recommended.
