 143
 144 Options:
 145
 146   -2, --2d
 147     Create 2D plot instead of 3D. Bigger window by default in gnuplot,
 148     and it’s faster when plotting lots of data.
 149   -h, --help
 150     Show this help.
 151   -l X, --label-file X
 152     Use X as label file.
 153     Default: $Std{'label-file'}
 154   -t, --time
 155     Use time as Z axis instead of elevation.
 156   -v, --verbose
 157     Increase level of verbosity. Can be repeated.
 158   -w X, --with X
 159     Use line type X:
 160       d  - dots
 161       l  - lines
 162       p  - points
 163       lp - lines with points
 164       Default: $Std{'with'}
 165   --version
 166     Print version information.
 167   --debug
 168     Print debugging messages.
