Best way to make a 2d color interpolation chart

[hecmar.arreola]

Hi!

I have LabVIEW 8.5.  I need to make a sepcialized color chart that relates to the magnitude of values that I'm aquired at different points along a 2d plane.  Essentially, what I want is to define key pixels across a bitmap image, and define those pixels in magnitude.  The boundries around the image are known and would be key pixels as well.  I then need to define a color gradient that relates to the magnitude and then interpolate between my key pixels to get some kind of an image.

Any input is appreciated.  I have a sense on how to do this and think if I work long enough at it I'd get there.  However, there may be an obviously easy way using one of the built in LabVIEW vi's that I have not discovered.

Thanks!

Hi Nic,

look for "griddata" examples, like described here! Or this one!

Hi Nic,

It seems like you are looking to achieve an intensity graph/chart.

There is an example in the NI Example Finder called "Intensity Graph and Chart Example.vi". This just shows a basic use of the intensity graph/chart.

Hopefully this helps!!
