I've tried the ondrawline event and set the toPoint.Y := FromPoint.Y, but then I get rumble during the dragging. A redraw isn't the solution too.

I'm using D7 + Tchart 7

ps. I want to use the right mouse button to drag a line.

Create labels on peaks with TFastline

Is it possible to draw labels with text on the peaks (I know the coordinates) of a TFastline?

I've tried to use the textvalue while using the AddXY function, but when enabling the labels, I see all labels for all datapoints, so not just the assigned labels.

I'm using V5.03 for D7
