class Differential1D:
""" Base class for displaying 1D differential plots.
Produces a plot comparing the baseline geometry (base) to the geometry specified by
the geom arguement. The quantity plotted is given by the "stat" option, and is
limited to the different statistics created by the StarBASE application. At present,
these include:
stat="radlen" :: plots number of radiation lengths of material encountered
... need to add more stats
The plot will show a solid histogram for the baseline geometry, with the comparison
geometry shown with red hashes. The fractional difference (baseline-comp)/baseline
is shown at the bottom in blue, scaled according to the alternate axis at the right.
base: selects the baseline geometry. [Mandatory]
geom: selects the comparison geometry. [Mandatory]
volume: selects the volume to be compared. [Mandatory]
geomvolume: selects the volume in the comparison geometry. [Default: same]
stat: selects the statistic to compare. [Default: radlen]
xmin, xmax: x-axis range. [Optional]
ymin, ymax: y-axis range. [Optional]
