Profile from an Intensity Graph?

[aamanuel]

Is there a VI to extract a "line profile" from an "Intensity Graph"?
Hopefuly, the profile could be specified using the mouse.
Thanks for any clue...

What do you mean by a "line profile"--a single set of data (1 dimensional array of points) taken along a line that is parallel to the x or y axis?

Hi m3nth,

I was wondering if you knew how to do what you've said....i.e. create a line plot from an intensity graph that is displayed on the front panel. Here is a link to an example of the intensity graph that I would like to be able to do the line plot with.

thanks

An intensity graph is just a 2D array. Simply slice out a column or row as desired.

The attached example (LabVIEW 7.0)  lets you graph the slice under the cursor on a waveform graph. It should get you some ideas. 🙂
