QDP is for everyone.

My sisters in work, Marykutty James and Jincy Devasia, who are X-ray astronomers, have been using QDP tool in the HEASOFT package for generating plots in their publications (Click their names to see their publications). As I was in need of plotting a number of data files, having very similar data, reached one of them to learn QDP.

QDP comes bundled with FTOOLS package from The High Energy Astrophysics Science Archive Research Center (HEASARC). As didn't have an installation of FTOOLS or HEASOFT, thought I would need to generate the plots on the workstation in our lab. But, thank God, it can be installed even if one do not have HEASOFT installed.

QDP (the Quick and Dandy Plotter) is basically a program that reads ASCII files and then calls PLT, an interactive plotting program that is designed to be used by scientists analyzing data. You can get it from http://wwwastro.msfc.nasa.gov/qdp/. Installation instructions and quick help on PLT/QDP are also included in the webpage. Note that, this is not a GUI based plotting program and works probably in linux only.
