[Dan Sebald]

Follow-up Comment #47, bug #47974 (project octave):

Oh, keep the patch example here for now.  Here is a fix for the data error:

but it doesn't produce a correct result.  I suspect it is because the using
clause is defined as


               usingclause{data_idx} = sprintf ("record=%d using
($1):($2):($3)", columns (data{data_idx}));


which isn't enough fields for x, y, cr, cg, cb.  I will take a look at this
later.
