Category scale fails to compute proper bar width when zoomed enough

[kurkle]

Expected Behavior

Bars should be sized properly

Current Behavior

Bars shrink after enough zooming. This happens because all of the data values are considered, and getPixelForValue is executed for each index. The method is limited to +/-32k pixels, which then results to too small distance between bars around those limits.

ok

not ok (zoomed one step more)

Possible Solution

Stop considering bars outside visible area, should perform better too.
