Quite possibly; I wouldn't really know.  However it would be less than
honest to plot the interpolated/inferred points as if they were genuine
data points.  By all means plot the interpolations, but distinguish  
them,
e.g. by joining them to their neighbours by dotted lines (where real  
points
are joined to each other by solid lines).
