I am using a waveform graph with multiple Y axis. As I am using only one cursor, Is it possible that when ever I move my cursor it displays x,y positions of all the plots on the waveform graph.
The MultiPlotCursor will display data across all of your plots that share a common axis. So if you have multiple y-axes that share a single x-axis, binding or setting MultiPlotCursor.HorizontalAxis to that x-axis will give you a vertical cursor that displays data across all of those plots, at least when they share x-values.
I realized you are likely talking about Windows Forms controls, while I was referring to the WPF graph. Unfortunately, my expertise is on WPF, not Winows Forms, so someone else will have to respond to your question.
Unfortunately, the cursor in Windows Forms is bound to only 1 plot. However, you can write your own custom methods to draw the cursor. In this forum post here, Vijet provides some sample code on how to do this.
