viewer for powder diffraction data

pxv - Powder X-ray Viewer

This is a very simple program to view 2θ - intensity data sets saved in text formats (such as .xy, .xye, .csv, .tsv). It was written to make comparisons, phase identification and recognition of multi-phase mixtures easier. Multiple data sets can be loaded, moved around, scaled and their visibility switched on/off. The plots can be exported as pdf, svg, png files and in other image formats.

Mouse buttons:

• Left: show coordinates & zoom in (drag area)
• Middle: pan
• Right: step back in zoom history

Clicking on the legend toggles the visibility of the corresponding pattern.

Compilation

You need Qt5 (>=5.12) or Qt6 and Qwt (>=6.1.4) installed and configured to compile the code.

mkdir build && cd build

qmake .. (or "qmake-qt5 .." or "qmake-qt6 ..")

make

and (optionally) make install

should work on recent linux distributions with Qwt installed. If you compile Qwt manually, qmake may be unable to find your qwt installation. This can often be fixed by replacing the

CONFIG += qwt

line in the pxv.pro file by

include ( /full/path/to/qwt.pri )
