Why do some of my cursors plot on a different scale than my datapoints?

[kc64]

I have an XYGraph with three plots.  All four scales are auto scaled.  When I plot the cursors on plot 0, all of the cursors appear correct.  When I plot the cursors on plot 1, only the x-axis cursors are correct.  The y-axis cursors are off by a factor of approximately 11.7.  I assume that this has something to do with a scale factor but I cannot isolate it.  I turned off auto scale and no change.  Any help out there?

Can you attach a vi that demonstrates the problem?

Open both VIs and run the test.vi.  You will have to zoom out to see the horizontal cursors.

Thanks.

Hi kc64,

This might be a big in LabVIEW. I'm going to take your example and test it a bit more. I'll let you know what I find out. Can you tell me exactly what version of LabVIEW you built these VIs on?

Thanks!

I ment to say "bug," not "big." I dont know what a "big" would be in LabVIEW 🙂

In your init cursor state, you are not assigning the cursor to a scale.  So it is always tied to the y scale for plot 0.  You need to tie it to the plot AND the scale.

Thanks to all of you for taking the time to help me out.  I updated my vi to write the X Scale and Y Scale properties based on which plot I am indicating and it works great!

I have attached the modified vi showing the cursor assignments in the Init Cursors state.
