qtgrace

Qt-based scientific 2D plotting tool (Grace reimplementation)

TLDR

Plot one or more data files (first two columns as X Y)
$ qtgrace [path/to/file1.dat] [path/to/file2.dat]
copy
Plot all columns as X Y1 Y2 ... with -nxy
$ qtgrace -nxy [path/to/file.dat]
copy
Plot with a logarithmic x-axis
$ qtgrace -log x [path/to/file.dat]
copy
Plot as X Y DY with log scales on both axes
$ qtgrace -log xy -settype xydy [path/to/file.dat]
copy
Show help
$ qtgrace -help
copy

SYNOPSIS

qtgrace [options] [datafile...]

DESCRIPTION

qtgrace is a Qt reimplementation of Grace (xmgrace), a WYSIWYG tool for displaying, analyzing, and preparing two-dimensional scientific plots. It shares much of Grace's command-line interface for non-interactive and scripted plotting.Data files are typically whitespace-separated columns. Options control axis scales, set types (for example xydy for data with error bars), multi-column layouts, and batch output. The GUI provides interactive editing; the CLI is useful for reproducible plots from scripts.

PARAMETERS

-nxy file

Plot all columns of file as X Y1 Y2 ...
-log x|y|xy
Use a logarithmic scale on the specified axis or both
-settype type
Data set type (for example xy, xydy)
-help
Display help and exit

INSTALL

yay -S qtgrace
copy

HISTORY

Grace originated as a continuation of ACE/gr for scientific plotting. QtGrace ports the Grace interface to the Qt toolkit for native Windows, macOS, and Linux builds while keeping compatible CLI options.
