caxis — CAXIS Pseudocolor axis
ax = caxis(value)
caxis(V), where V is the two element vector [cmin cmax], sets manual scaling of pseudocolor for the objects created by commands like pcolor, surf, surfl. cmin and cmax correspond to the first and last colors in the current RGB colormap. Values outside the range are clamped to the first or last colormap color.
caxis('manual') fixes axis scaling at the current range.
caxis('auto') sets axis scaling back to autoranging.
caxis() returns the vector [cmin cmax] currently in effect.
