Obtaining two point from graph

Solved!
Go to solution
Hi there, 

I would like to find a slope of a graph (please refer to figure below) by pointing two points using cursor. Graph.jpg

However, the method shows in the LabVIEW group doesnt help much as it is too complicated for me. Please refer to this link .
 
Hope somebody could help me on this.

Hi Fird,

 

use a property node to read the cursor positions and calc the slope by (y2-y1)/(x2-x1) Smiley Wink

Hi GerdW,

 

Thanks for your response. Do you and example of using the property node. Or is it possible if you could show any figure of the example.

 

I tried already but seems not correct. Hope you could assist.
