This is a modification of previously submitted APPLYHATCH_PLUS.
APPLYHATCH_PLUSC creates a bitmap version of the defined figure where colored elements are replaced with specified colored hatch patterns.
APPLYHATCH_PLUSC allows for the definition of colors for the hatch patterns. Color may be defined using char string or RGB values. Various examples are provided showing some possibilities of APPLYHATCH_PLUSC and MAKEHATCH_PLUS.
Note: This function is different from Brandon Levey's APPLYHATCH_PLUSCOLOR, which has slightly different functionality and syntax.
applyhatch_plusC applies to the entire figure, subplots included, so I don't understand the question. You cannot, however, use different hatching rules for two subplots. But, if you assure that the original subplots do not have any colors in common, you should still be free to make the results be anything you want.
