Origin Ver. and Service Release (Select Help-->About Origin): 8.6
Operating System: WIN 7
I have a uniformly gridded 200X1600 (y&X axis respectively) matrix (a ccd image data) of z values. I want to convert it to a nonuniform gridded matrix where the nonuniform gridding comes from the fact of calibrating the X-axis (from pixel to raman shift for ex.). Basically I want to create a 2D surface plot with X axis is now raman shift instead of pixel number. I have the pixel to raman shift calibration file.

You can use virtual matrix to plot surface. Origin's virtual matrix supports nonuniform xy. See the page:

and the video tutorial:
