Hi,

You can add 2 cursors by right clicking on properties of graph/chart. And right click on graph, select visible items, Cursor Legend.

If you want to read the x-axis cursor values programmatically use property node, Cursor position.

See attached.

Hope this helps

First of all.. Your attachement is not visible..

Second.. as a general understanding.. You can create two cursors and read their corresponding positions programmatically..

Hi Mirash,

I attached again, from the below graph i like to get the X-axis values of both cursors programmatically.

when ever the two spikes occured i want the time occurence between them.

 From the i can able to get X-axis value statically.

Thank you

Hari,

You can follow the same method as GITA mentioned in the above post.

The attached VI has the same implementation.

Hi Mirash

I did the same, I got the values by manualy moving the cursors.

But i want it by automaticaly, when ever the signals acquired cursors should point it automaticaly

and get the values without moving the cursors manually.

thankyou so much..Your image of the implementation was so perfect!

I have the same desire to put two vertical cursors on a graph and then choose to expand the X axis between the two cursors.  Obviously, there would also need to be a 'reset' to go back to full X axis scale.  I want to do this programmatically.  I know the tools already do this..   Thanks in advance.
