Idea Summary
At the moment, bar width can be controlled by setting the height of the chart region. By setting a constant height for the chart, in the case of having a variable number of rows in the chart (depending on the user and the data at the time), bar widths could be really small or really big.

Use Case
In the cases that the number of rows displayed in the chart dynamically change, chart should adjust itself.
Preferred Solution (Optional)
It would be good if we could select a (minimum) bar width in the properties and the height would adjust automatically.
