Eli and chatted about this a little yesterday...
At the low level, this could be implemented by a new data object: KstVectorView (or some other name).

It takes as inputs an X vector, a Y vector, and a view range (xmin, xmax, ymin, ymax) and it outputs X/Y vectors over the defined range.

The only sticky bit is interpolation...  there are a couple options here:
-merge the VectorView into curves, and give curves outputs
-split interpolation out of curves into a new data object KstInterpolator.
-Let KstVectorView interpolate, keep everything else the same.

I favour the third option (but I think Eli favours the second).

In any case, we could then create a few different UI's for creating KstVectorView objects - eg, by the fit dialog.
