plotting and fitting on same plot

I have to do spline fitting on 4 data files and then plot the original points plus the spline fitting on the same plot.. each data file has to be denoted by different colors

What is your question then?

Thanks for sharing Aditi ;)

But really, we aren't sure what your question is.

If you just have no idea where to start, look into the following commands/functions and see if they help

spline
