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

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