Search the ITTVIS Code Contribution Library for POLY_SIMPLIFY by Brad
Gom. This function simplifies the vertices of an n-dimensional
polyline.

Hi,
Take a peek at the built-in SPLINE function.
You can see an example (copied below) in the docs, but adding plot
seals the deal.
X = [2.,3.,4.]
Y = (X-3)^2
T = FINDGEN(20)/10.+2
Z = SPLINE(X,Y,T)
PLOT, X,Y
PLOTS, T,Z, PSYM = -6
Cheers,
Ben
