I have a composit char that has many stepline layers. Each layer has a Y axis with different min/max range.

When I click data on a chart, I made show the lables of the Y axis used for the clicked data.

Then I want to show some unique text next to the Y axis (between the labels and the left edge of the control)  the  when clicking data.

Is there any easy way to do it?   Does a TitleLayer support a title on a right/left side besides top/bottom?

Thanks,
