• Plot one or more data files, plotting only the first two columns in each file as X Y:

qtgrace {{path/to/file1.dat path/to/file2.dat ...}}

• Plot one or more data files, plotting all columns in each file as X Y1 Y2 ...:

qtgrace {{-nxy path/to/file1.dat -nxy path/to/file2.dat ...}}

• Plot one or more data files with a logarithmically scaled x-axis:

qtgrace -log x {{path/to/file1.dat path/to/file2.dat ...}}

• Plot a data file with a logarithmic scale on both axes, with data formatted as X Y DY:

qtgrace -log xy -settype xydy {{path/to/file.dat}}
