Plot vertical line over a graph

[Oliveira]

How can I plot a vertical line over a wave chart when I click over the
graph?

Thanks in advance!

You could just protgrammatically move a cursor to the desired position. Do you want the line at the location you clicked or elsewhere?

What is your LabVIEW version?

[Oliveira]

At the location that I click. Do you have an example that could send me?

Thanks.

Look again in my post. I also asked for your LabVIEW version.

This is important, because newer LabVIEW versions have much better tools to do things like that and the answer will strongly depend on the version. 😉

Sorry, I am using LabVIEW 8.2

Thank you again.

To get the coordinates of the place you clicked, you can use a techniquew similar to one of the shipping examples. Open your example finder and look for the example "draw graph with events".

Once you have the coordinates, you can move a cursor to that location using a property node. Alternatively, you can draw a line using image tools together with the "plot.images" technique. For this, have a look at the example "graph plot area images".

See how far you get. Good luck! 🙂
