How to drag a point in the linegraph using Dynamic data display

May 12, 2015 at 7:39 AM
Hi,

I am using Dynamic data display for drawing a linegraph on the chartplotter.
But now i need to place the draggable points and should be able to move the points,so that the linegraph should re-draw itself.
As of now i couldn't see any built in function in dynamic data display which does it.
Please help me regarding the same.

Hi Venkatesh,

You can not do this with LineGraph. Instead you can use ViewPortPolygon.

You might have used "CompositeDataSource" Or "EnumerableDataSource" to draw the line graph.
This CompositeDataSource gives you the points collection CompositeDataSourceObject.GetPoints(), these points you can map to ViewPortPolygon Points.

Ravi.
