7# DESCRIPTION
8# This script operates on the .dat file generated by bb-matrix.sh. It tolerates
9# the header by skipping the first line, but error messages and bad data records
10# need to be removed first. It will generate three views of the plot, and leave
11# an interactive view open for further analysis.

30 -d datfile The data file generated by bb-matrix.sh (default: $DATFILE)
31 -f field The field index to plot as the Z axis from the data file
32 (default: $FIELD, "$DEF_TITLE")
33 -h Display this help message
34 -s W,H PNG and window size in pixels (default: $SIZE)
35 -t title The title to display, should describe the field (-f) and units
36 (default: "$DEF_TITLE")
37 -w Render the plot as wireframe with a 2D colormap projected on the
38 XY plane rather than as the texture for the surface
