Support vmin and vmax for bars

[domoritz]

plot.bar(colormap=cmap, vmin=0, vmax=5)

Problem description

vmin and vmax are not supported. #21526 adds support in the styler but not the bar plotting itself.

Expected Output

The color range should be set.

Can you make the example at the top a full one? That helps us know exactly what we need to achieve to close this issue.

Ah, it's in color. Answer in #21526 (comment).
