Prism can interpolate from several data sets at once. To do this, put all the unknowns on lower rows on the data table than all the knowns (left panel). Prism won't be able to interpolate past the first data set if you put the second data set below the first set of knowns (right panel).

Yes! All unknowns at the bottom.

No! Unknowns everywhere.

Why can't Prism handle the kind of data shown in the right panel above? Because then it might get mixed up about which values are unknowns to be interpolated, and which are simply adjacent to values left blank because they are missing.
