How about returning the colorbar limits from pcl(), and using the
larger extent of those limits and the ones from the scatter data when
you call the colorbar in sct()? (ScalarMappables have get_clim(),
set_clim().)
Or, more generally, record the data limits and have both functions
check them, in case someday you want to call pcl() after sct().
In general, I like the figure style for an experiment or case to be a
class, with plotting functions like the ones you've already written
but data members that either pretty up the functions, or are useful
for other reports ('Variability and drift between runs'...), etc.
