fortplot_matplotlib_plots Module

Matplotlib-compatible plot functions for imshow/pie/polar/step/stem/fill.

Color kwargs accept either a named color string or an RGB triple via generic interfaces. fill_between makes y1 required to match matplotlib's contract. fill accepts an optional step stage to mirror matplotlib's stair-fill mode.
