================================
Demo Colorbar With Inset Locator
================================
==============================================================
Controlling the position and size of colorbars with Inset Axes
==============================================================

This example shows how to control the position, height, and width of
colorbars using `~mpl_toolkits.axes_grid1.inset_axes`.

Controlling the placement of the inset axes is done similarly as that of the
legend: either by providing a location option ("upper right", "best", ...), or
by providing a locator with respect to the parent bbox.
