Hi Angie,

are you sure you do have more y than x values in your data arrays, or
do they just appear like that in the scatter plot, because you have
many identical x values? Besides, if you have more y than x values, I
wonder how you actually do the scatter plot. And, well, you used
CURVEFIT, so I guess you actually do have all the apropriate data
points. In thas case, you should just give POLY_FIT a try. Don't bother
about y values scattering for one and the same x value. That's just
what cuve fitting is about, isn't it?

Cheers,

Peter
