What is WinPLOTR?

WinPLOTR is a program to plot powder diffraction patterns. It can be used to plot raw or normalized data files coming from neutron and X-ray diffractometers (conventional or synchrotron radiation) as well as Rietveld files created by the FullProf refinement program. WinPLOTR can also be used as a Graphical User Interface for programs used frequently in powder diffraction data analysis (ex: FullProf,DicVol ...)
or other external programs defined by the user.

WinPLOTR has been developped to run on PC's with a 32-bit Microsoft Windows operating system. WinPLOTR supports Windows 9x/NT/XP. WinPLOTR has been build up with Lahey Fortran 95 compiler, using the Windows facilities of RealWin.



  • Several data file format (neutron, RX, synchrotron, time of flight)
  • Choice of X_space: - 2theta (deg) / Time of flight (microseconds) / Energy (KeV)
    • Q (A-1) = 4pi . sin(Theta) / lambda
    • d(A)
    • - sin(Theta) / lambda (A-1)
  • Graphic options: cursor, zoom ...
  • Plot options:
    • Change colors, markers type and size, styles...
    • Shifts data
    • Hidden parts management
  • Select and save points with the mouse
  • Automatic peak search and fitting
