Fit2d is perhaps the 'gold standard' for making powder diagrams:

For source code try:

Good luck,

Jon

> 1) Some data collection and image processing files have the options to show the intensity distribution over a user-defined "line" in the image. Does any program allow one to trace a line from the beam center to the detector edge and save this intensity distribution to a file, so one could have I vs. 2theta data (or even a I vs. pixel data file, which could be easily converted to a I vs. 2theta file given the experimental setup)?
