I would like to know if there is a simple way to make the image change of a more elaborate chart, such as those made with the framework:

I was able to do it with canvas, but it is very simple and laborious to do the subtitles

B4X:
' Scrolls the image
Canvas1.DrawImage2(Canvas1.Snapshot, 0, 0, Canvas1.Width - 5, Canvas1.Height, 5, 0, Canvas1.Width - 5, Canvas1.Height)
' Clean start area
Canvas1.ClearRect(0, 0, 5, Canvas1.Height)
' Draw start area
Canvas1.DrawLine(0, Num1, 5, lastPoint, fx.Colors.Red, 1)
' Save last point
lastPoint = Num1
