I have a slightly kluge-y way of doing this on the Apple.
First, I create a graph using the Interactive Microware, Inc.,
(State College, PA (814) 238-8294),
package called Graph-Pak ($145). I use the section called Scientific
Plotter, which is available separately for about $30 or $40.
You can input your data by hand, or read it from a disk file.
If you want, you can use their Curve Fitter program, available
separately for $35, to fit the data with various smoothing
schemes. The fitted data can then be passed back to the
Scientific Plotter for axes and numbering.
Once you have the final graph, it is usually dumped to a graphics
printer, using a Pkaso-U or Grappler+ parallel card. Instead, I
save it to disc.
However, since I have a serial printer, both a C. Itoh dot-matrix,
and a Qume daisy-wheel printer, I opted for something else.
Smartware of Dayton, Ohio (513) 426-3579, makes a software package
called ADVANCED GRAFPAK which lets one dump HGR screens 1 and 2 to
almost any printer, dot-matrix or daisy-wheel, using either serial
or parallel cards instead or a hardware graphics dumper.
It is not as fast as a dumper card, but it is reasonable,
especially at the $35 price. It is also available from
Interactive Microware, Inc. I then load one of the graphs from the
disc I created above, and then run it using this GRAFPAK. You
have a choice of printing characters; I use the period for the
I think the Roger Wagner Software program called
PRINTOGRAPHER also serves a similar function to ADVANCED GRAFPAK.
You still need to create a hi-res graphics screen to dump from.
