Chart.FirstVisibleBarIndex gets shifted when chart is scrolled to left

when scrolling to left more historical data is loaded and this causes Chart.FirstVisibleBarIndex to shift making controls shift to right.

And it makes sense because the first visible bar changes. 

What are you hoping or expecting to happen?

if display a control for example button it displays incorrectly (shifted to right to the middle of screen) when its x is set to FirstVisibleBarindex.

 

it displays correctly initially until chart is scrolled to extreme left causing preload of more historical data. then firstvisible bar calculation is messed up
