Gates on XY Graph

[M.Siddeq]

Hi

I want to create gate on XY graph which I intend to configure for ultrasonic A-scan dispaly, how to draw plots between cursors to establish the gate?

Thanks

Using a property node for the graph you can set up cursors for the beginning and end. This will required two cursors. In the property node you can set the X or Y start position for the cursor to set the gates. You will need to set the active cursor and then the cursor position properties.

thank you for the kind response
I am quite fresh with LABVIEW and I was thrown on this task with no assistance, so I will trouble you a bit
My task is: build an ultrasonic A-scan (input: Tektronix machine, output: xy graph detailing apmlitude,time values as well as gate controls)
Your detailed guide will be much appreciated

Thanks again

Please have a look at the very first trial:

OK I do not see the cursors for the XY graph. Also can you post your code so that I can help you with the updates? I can see what I can do to help you get where you are looking to go.

I think that we can use threshold vi's to get you where you want to go. Do you have actual data that you can provide that would allow for us to use whlie we are trying to get your program to work?

I used onli express VIs to build the above proposal...

The cursors and plotsI have set from the XY graph properities....I do not know if it is the right way,,,,

The actual data is ultrasonic wave from an oscilliscope through signal express Tektronix edition but I do ot know how to use LABVIEW to simulate such data

Many appreciations

You should be able to hook your ultrasonice sensor to LabVIEW via a data acquisition card or vis communication to your O Scope to get the data into LabVIEW. It seems that you will unlimately have to do this anyway.
