Rotate and format cursor labels on graphs

Status: New

In many spectral monitoring applications such as vibration spectrum, electrical power spectrum and other frequency analysis, it is standard practice to label peaks in the FFT graphic.  To do this in LabVIEW, we use cursors and cursor labels to point out specific frequency of interest.  However, LabVIEW does not allow the fonts and rotation of cursor labels to be adjusted either manually or programatically.

It is common practice to use a cursor marker on the peak of the FFT frequency, with its label in a vertical orientation.  Here is a common peak labeling practice used in most all vibration spectral applications:

It is painful to create work around such as programatically relocating cursors, writing text on graphs, etc.  Is it possible to add at least the rotate cursor name property to LabVIEW?

 

Here are some other posts I have seen in the discussion forum related to this topic.

I look forward to comments and feedback.

Preston,

 

I support very much your idea and I'm dreaming about this:

Dear Preston,

 

That's exaclty what I'm looking for.

 

Adding a property to the cursor list, as then added recently the "Label Offset" cluster, should be easy. Enum choice like for vertical arangement of label would be enought for most needs, but a full 360° orientation value should open more further designs.

 

I hope it could apear soon.

 

Best regards,

 

Daniel
