I will supplement the above comment of Scott. In RIETAN-94 for the (Power)
Macintosh, I implemented a feature of drawing Rietveld-refinement and
simulated patterns automatically with Igor Pro (WaveMetrics). I am an
enthusiast for Igor Pro, which makes it possible to include a series of
commands to plot figures in addition to refinement results in Igor text
files. In the forthcoming version of RIETAN-94, only double-clicking the
icon of an Igor text file is adequate to run Igor Pro and read in the text
file. Those who are interested in such a feature are recommended to refer
to the source program of RIETAN-94.
I also added a feature to create files in SigmaPlot (DOS and Mac).
However, creating template files is necessary in this case because we
cannot append commands in data files with the SigmaPlot format.
I have been enjoying the automatic drawing of Rietveld-refinement patterns
(both TOF neutron and angle-dispersive diffraction) with Igor Pro. With
such graph-drawing softwares, we can change scales (x and y), lower and
higher limits (x and y), character sizes, magnification ratios, colors,
labels, and page layouts very easily. Needless to say, any type of
printers can be used for printing out the Rietveld-refinement and simulated
patterns. In addition, it is very easy to export the patterns to files
with the EPSF format; they can be read in by various graphic softwares,
word processors, and DTP softwares.
The only disadvantage of such a manner is that we must buy Igor Pro,
anyway. However, Igor Pro and SigmaPlot can be used for many other
purposes, which is the reason why I prefer them to sharewares such as
DMPlot and SPLOT. Nevertheless, I will implement a feature to create files
in the DMPlot and SPLOT formats in a future version of RIETAN-94 because it
is exremely easy for me.
