BarChartView shows on UI when y value is zero

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

I'd like to know if it's possible to the draw a bar just to indicate the value zero.
By using a BarChartView, I'm able to achieve this result:

Notice that on "jan" the positive and negative values are zero. But visually, it doesn't show anything (since is zero of course)

What did you expect to happen?

I want a a bar indication even when value is zero. Like this:

Is it possible? Thank you.

then you have to modify the code yourself like provide a small rect if rect is zero.
