Synchronise Crosshair/Trackball in multiple charts on winform

Hi,


I have 3 charts on a window (stacked horizontally) and I want the crosshair (the vertical line specifically) on top chat to be syncronised and visible on bottom 2 charts. Can you please let me know how can I do this ? The X axis for all the 3 charts have same value.


Thanks,

Amit

Hi Yuvaraj,


Sorry if my requirement was not clear enough. Attached below an image of how I want the crosshair to function. I have 3 Chart Controls on a Form and I want the CrossHair on ChartControl1(The Crosshair's Y Axis Bar )  To extend on ChartControl2 And ChartControl3 As shown below image. Please suggest how I can achieve this.




Thanks,

Amit
