If I scroll to the right then the bar yyy ot back to the bar xxx then the bar is calculated and the rectangle ges drawn.
As result the rectangle does not show up until I scroll horizontally the chart to that bar right and back to where I was. This forces me to a continuous scrolling back and forth.
Maybe I can resolve the problem by forcing the drawing of the rectangle just to the visible bar to the chart of the window.
Is that a way to find out which are the bar numbers at the right and left of the visible screen?
Or is there an intelligent way to resolve the issue?
Thank You
