You
can use TChart.OnAfterDraw event to put almost anything on the Chart
Canvas. The only problem is the additional
"objects" coordinates are expressed in screen pixels. When you resize, scroll
or zoom Chart, these coordinates do not change.
This
sample application shows you how to draw annotations and arrows
directly on the Chart Canvas, and zoom and scroll them.
This
application was developed and kindly provided by Jens Munk (Jens.Munk@maccor.dk)
