Hello all,
Can any knows about this?
As we all know we can display data into Graph ( as per my attached VI Step-1). But, I want to Read Data from Graph.
I mean, I want to create GUI for Graph (Control) and User can Insert values /user will Draw lines on graph by mouse. Based on that I want to read (like Step-2).

Hi Munna,
when your user is "drawing" points using the mouse you already know all coordinates. You only need to store them in an array - and afterwards you use that array to display a plot on the graph!
It's kind of DATAFLOW: You don't draw magically in the graph and read out the plot data.
First you track mouse movements to get XY coordinates, then you store those coordinates in the array, then you plot that array in the graph!
