Hi Peter,
How can I draw an arrow at the end point of a line created by DrawArea method?

Hi Thexder HO,
For XYCharts, arrows can be added by using the VectorLayer. But for DrawArea, I would just draw a rotated triangle as the arrow head. You can use the DrawArea.polygon method to draw any polygon, including a triangle.

Another method is just to draw 2 lines to form a "V" shape as the tip of your line to act as an arrow.

Hi Peter,
yes Peter, you are right,
after going through the supporting document in detail, I managed how to achieve it,
you method suggested is the best way to it this. other methods will cause the program looks more complicated and inconsistant.
thanks!
