How to display spectral lines in color band

[jackjern]

Hi Shane, just wonder if you are home yet.  I was trying the picture control for the past few days but didn't get anything positive.  I apologize if you bother your vacation.

No, no problem.  I've been home since but I'm very busy at the moment.  I'll try to get something posted soon.  Sorry for the delay.

Hello Jack and Shane,

Do you mind sharing your code, or the idea of doing it?  I am working on something very similar, but not spectral line related.

Thanks in advance!

Could you post your example vi here? I also need to solve this problem.

I try to make a example, see attached.

Wow, 5 years ago I promised to deliver example code.   I don't have it on my current computer, I'd have to try to dig it up at home, it was written in LV for Macintosh version 8.2.1.

I'll have a look and see if I can find anything useful, I promise.  It'll only take me 3 years to respond this time.....

Maybe he tried to make an example and failed?

As far as I know, to create a color spectrum you need to create triplets of R-G-B values. Here's a simple example to create a PSEUDO color spectrum:

If you want to create a real color spectrum the R:G:B Triplets should look like this instead:

So, ronke what does your code behind the screenshot you posted look like?
