I used to use Interactive Microware's Scientific Plotter and theire
other program, Curve Fitter.  It can output to an Imagewriter, and
can use an HP plotter for an extra cost.

It only plots one set of data per graph.  I wanted multiples, so I
would save each graph (it uses HGR1 or 2, I don't remember which) as a
BIN file.  I have a machine language rountine that OR's two screens,
so with multiple graphs with the same axes, I can just sum the images.
I can put as many graphs together as I want.  It gets awkward since
they usually have the same symbols for data points.

The Curve fitter program let me use polynomial and other fits to the
data, which can also be superimposed with the original data points.

The programs were not expensive, something like $25 to $75.  They are
written in Applesoft BASIC, so they can be modified also.  I did some
mods that let me run in an automatic mode, where the data would get
read in, curve fitted, plotted, and saved to disk, and then go one to
the next dataset.
