ENH: Display worst features with barplot

oasidorshin opened this issue · comments

Problem Description

Current plotting tools focus on showing top performing features. A lot of times in practice you also uses SHAP to find and remove some useless or badly performing features.

Even trying to use some workarounds I couldn't display the worst features using current plot tools, and ended up resorting to just displaying all features, and scrolling to the bottom.

Possible interfaces would be either additional parameter descending=False, or negative indexing with something like max_display=-20.
