How to force waveform graph cursors to show Y value on more than one plot?

[pawel]

Hello
Is it possible to show more than one Y value on waveform graph cursors?

Thanks in advance.

What's the other Y value that you want to display? Is it the Y value of a point on another plot? If that's the case, ue the property Cursor.Index to get the position of the cursor and you can use that as an input to Index Array to get the value of the other plot at the same moment in time. If that's not what you want, could you explain further.

Hi Dennis
That is correct, on graph woth multiple plots I want to display multiple Y values of plots at the same X value.
I know I can use property node to access cursor list etc. and this is how I have done it, but my question was rather if it is possible to force the cursor legend to display more than one Y value (as a native display). As a default it displays one value and you can choose which plot you want to stick to, but it would be a great feature to have possibility to expand cursor legend to display more than one value.

The question has nice consequences. If it was possible, you could use a property node to export image of the graph, control sizes, or even simple "copy" data from the popup menu. Otherwise we need to "artificially" glue the exter
nal controls displaying Y values if we want to export pictures, etc.

But since you did not answer that I supose it is not possible, as I thought.

thanks anyways.
kind regards

I don't know of anything that can be done without a bit of coding. If you want to use the cursor legend, then you can create a second cursor attached to the second plot and then use property nodes so that dragging one cursor also moves the cursor on the other plot. I think that besides Free, Snap to Point, and Lock to Plot, a Lock to Other Cursor would be a nice additional to LabVIEW.

Lock to other cursor is a great idea. Than you can call them in the same way as the plot is called or what ever interpretation you have in mind, and with one mouse move, move also others. I like it a lot. Maybe you should try to sugest it to NI and we will see it in the next release.
