Get Coordinate of Center of Column for Each Side-By-Side Stacked Columns

Hello,

I am using two StackedColumnRenderableSeries in my chart, but following the example “Stacked Column Side by Side”.

I am trying to add a text annotation that will contain the actual value of each column at the top of the column (very similarly as it is shown on the example “Histogram”).

The problem is that I’m able to get the data point position, not each individual columns centered position.

I have inherited from StackedColumnRenderableSeries, and there’s a method called GetColumnCenterTopAndBottom but the center value is not as expected.

In the attached image I show the positions I want to get (marked in blue).

Is there a way to get these values?

Thank you.
Sebastian
