This example shows how to place different plots in the same figure using orix’ various plot types, which extend Matplotlib’s plot types.

By first creating a blank figure and then using add_subplot() to add various orix plot types, we build up a figure with two rows and two columns showing separate orientation maps (IPF-Z maps) of two phases, a pole density function (PDF) and a discrete pole figure (PF).

Austenite IPF-Z, Austenite $\left<111\right>$ PDF, Ferrite IPF-Z w/score overlay, Ferrite $\left<111\right>$ PF
