 149
 150 Options:
 151
 152   -2, --2d
 153     Create 2D plot instead of 3D. Bigger window by default in gnuplot,
 154     and it’s faster when plotting lots of data.
 155   -h, --help
 156     Show this help.
 157   -l X, --label-file X
 158     Use X as label file.
 159     Default: $Std{'label-file'}
 160   -t, --time
 161     Use time as Z axis instead of elevation.
 162   -v, --verbose
 163     Increase level of verbosity. Can be repeated.
 164   --version
 165     Print version information.
 166   --debug
 167     Print debugging messages.
