The BB and PM ranges were originally intended to use leading 0s to ensure all the values were the same string length, making for nice log filenames and columnar dat files. However, not everyone will do this - especially if it isn't documented. Document the intent. Make the generation and parsing of dat files robust to either method.

# 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
