Hi,
Is there an example anywhere of a user being able to click on a chart and auto-create a line annotation based on when the mouse button went down and where it went back up again after the mouse was dragged ?
This seems tantamount to drawing a straight line and then adding a label to it.
They would need to be able to add multiple lines.
They would need to be able to delete lines.
We need the ability for users to create their own annotations directly within the chart area, using their mouse.
Thanks,
Barry

Hello Barry,
This is not supported by the chart. In order to achieve your requirements you can use chartview and its annotations feature. And implement some custom code for the interactions, using the mouse events (MouseLeftButtonDown, MouseMove, etc.). To draw a line on the chart you can use the chart's GridLine annotation.
