 147
 148 Options:
 149
 150   -2, --2d
 151     Create 2D plot instead of 3D. Bigger window by default in gnuplot,
 152     and it’s faster when plotting lots of data.
 153   -h, --help
 154     Show this help.
 155   -k, --keep-files
 156     Don’t remove temporary files after program execution.
 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   -w X, --with X
 165     Use line type X:
 166       d  - dots
 167       l  - lines
 168       p  - points
 169       lp - lines with points
 170       Default: $Std{'with'}
 171   --version
 172     Print version information.
 173   --debug
 174     Print debugging messages.
