Question:
A user has encountered the following scenario:

They have a 2D array with x-values of the image, a 2D array of the y-values of the image, and a 2D array of the image values. The image is a wedged shaped thing and not rectangular. The user is looking for something like the TV or TVSCL that allows the X and Y coordinates to be provided.

Answer:

The IMAGE function allows you to provide the X and Y coordinates. The documentation for this routine is shown below:

Alternative route could be to grid the data using the GRIDDATA routine:
