 145
 146 Options:
 147
 148   -2, --2d
 149     Create 2D plot instead of 3D. Bigger window by default in gnuplot,
 150     and it’s faster when plotting lots of data.
 151   -h, --help
 152     Show this help.
 153   -l X, --label-file X
 154     Use X as label file.
 155     Default: $Std{'label-file'}
 156   -t, --time
 157     Use time as Z axis instead of elevation.
 158   -v, --verbose
 159     Increase level of verbosity. Can be repeated.
 160   -w X, --with X
 161     Use line type X:
 162       d  - dots
 163       l  - lines
 164       p  - points
 165       lp - lines with points
 166       Default: $Std{'with'}
 167   --version
 168     Print version information.
 169   --debug
 170     Print debugging messages.
