Zero data and minBarHeight=0 breaks multiple columns in BarChart

[damonmaria]

🐛Bug report

Describe the bug When multiple columns are supplied for a BarChart, and minBarHeight={0} is used, then the first column that has 0 data will stop later columns rendering.

This happens because this line of code should continue, not break.

To Reproduce #364 has a good example that produces this.

Expected behavior Even when one bar is zero height, the other bars should render still.
