+# 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.

+  -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
