I placed the patch on S.F. under a new patch entry.

I like these sorts of patches because they are tutorial and a good check some times for when bugs are introduced.  We've caught several that way in the past.

I still am wondering if there is a purpose to having both a datafile missing string and datafile undefined string.  Somehow it seems to me the user could have both such items at the same time and want there to be different behavior based upon type.

Anyway, attached are the PNG images for those not tuned in to the discussion (AFTER THE PATCH).  We can see what Ethan is talking about for the example where the line dips down to (3,2) in the two column data case.

I'd like to add an example or two for the 3D case so we can modify and test proper behavior, but don't want to have so many data points inside the demo file.
