Graph cursor problem


Recommended Posts

Hi all,

i am relativly new to LabView. I am working on an editor for digital data. To display my data i use a Digital Waveform Graph. To do the editing i am using the cursorpos i read out of the property node. But when I try to set the cursorpos either by typing in a numerical value in the cursorpalette or programatically by writing to the property node, I end up with wrong values!?!

For example, the graph diplays data from 0 to 10000, I type 487 for X-cursorpos and LabView alters my input to 480 and places the cursor at 480.

I tried some values

[typed-input -> altered to]

487 -> 480

488 -> 495

500 -> 495

502 -> 495

503 -> 510

518 -> 525

Is this the normal behaviour?

Goetz,

probably the cursor is locked to the waveform.

Unlock it by right click on the lock and choose free.

With regard to yor data: Have you actual 10k samples? If you connect an array indicator, what values do you actual see if you at register(location)ie 487

Why not do your editoring via data handling , then present result via Graph ?

What is your plot resolutio :rolleyes: n?

Yes I tried with full and sparse data, every time the same.
