Dear forum users, I am an absolute beginner with IDL and I have a problem which I can’t solve by myself. I am using IDL Version 7.1 and I try to create a simple intensity plot. I have three vectors (1d arrays): x, y, and z. x and y are the coordinates for the z value. x and y are not equidistant (only approximatively). Until now I used iimage,z,x,y which produces with the IDL Gridding Wizzard nice images but not the images I want to have. I do not want that my data are connected by a gridding/interpolation method like inverse distance and so on (see result-picture)! I just want to plot my data as they can be seen in the IDL Gridding Wizzard (see wish-picture ). Can anybody tell me how I can achieve my aim? I would be very thankful for every help!
