Toggle data visibility for bar charts should expand remaining bars to fill the space

### Feature Proposal

Currently, toggling data (not dataset) visibility for bar charts causes a bar to animate away, leaving an empty column where it used to be. This feels not very useful, as the space isn't reclaimed. I think the real value of hiding some bars is to allow the remaining ones to be more legible, by using that space.

For example, a dataset containing 50 unique datapoints could show only 10 of them, and have a legend which allows toggling each category. As new ones are checked, the bars would shrink and include a new one. With the current setup, the initial 10 would only use 20% of the chart area. I don't see a way around this other than passing in a different dataset as categories are checked, which feels redundant with the visibility state within chartjs.
