0 Replies and 985 Views Best way to plot 2dimensional data as density map  985  0 Started by  Deleted User Hi, I am new to IDL and I have the following problem.

The intensities, which are arranged in a 2-dimensional matrix, should be plotted as density plot. Afterwards I would like to change the color map of the image, the contrast, etc., and I would like to measure profiles at different points in the image. Which routine should I use for plotting the data. First I trie...

0 Replies and 959 Views colorbar  959  0 Started by  Deleted User Hi, I have another question about colorbar. I'm ploting with 'contour' right now, but I didn't find an easy way to add colorbar for it. What I do currently is to download Dr. Fan's coyote library and run "colorbar" commander after it. But I guess idl should provide some straightforward method for it. Can anybody give me some hint or suggestion Thanks a lot!

0 Replies and 898 Views Loading in Consecutive Data Files (.csv)  898  0 Started by  Deleted User Hello All, I would like to create a .pro routine which reads in a number of consecutive .csv files which are randomly named in the same folder. For instance there might be 100 randomly named .csv files in the same folder. My question is: how do I load these into IDL and assign each of these files a matrix name ie. M1, M2, M3, M4 etc. in order that I can carry out mathematical manipulations on them or visualise them Thanks, Nevica
