I need a curve fitting algorithm and I like what LO does in ods. Can any one point me to where I can take a look at it, or, send it to me, or, describe it? Most appreciative.
I’m not sure what you mean with “curve fitting algorithm”. Something like the following?

I’m not sure. I have a graph with 1024 plot values. What I see when I select" lines/lines only" is a pretty with all the individual plot values suppressed. I would like to replicate this graph using the same plot values. I think that when LO outputs a graph, it either selects the points to use, averages the points in some way, or, as you suggest, do something like fitting to a cubic spline. What I was hoping is that there was something I could look at that would describe the process.
