Does anyone out there, have, in any language (high level), for any
computer, a program which will do simple two dimensional curves on a
Diablo printer. I type lots of lab reports and am tired of plotting
curves by hand. I have seen that Diablos can do simple graphics,
that's all I want. The ability to read in say four sets of X,Y data
points into the same graph would be nice. Any help in the area would
be most appreciated. BitGraphics and Character Graphics programs are
both quite acceptable.

Diablo Hytype II mechanisms are supported by "tplot -T450", which uses the period (make sure you have a metal-reinforced one) hammered all over the page to draw vectors. Not terrific, but it already comes as part of the standard UNIX plot utilities so you may as well use it. An improvement might be to rasterize the vectors and print rows of dots in raster order; this would usually be slower. As to the software for generating the device-independent plot data in the first place, look up graph(1G) and the graphics(1G). The "gtop" utility can convert the latter (GPS-based) graphics to UNIX plot(4) format with some loss of beauty.
