  Subj: HP48: connecting SCATTER: the easy way.
  Date: Mon Feb 18 1991

There was a discussion about making a SCATTER plot with connected lines.
Here is a simple way to do this without programming whatsoever.

First, do the regular preparations for a scatter plot, and press SCATTER.
This sets all parameters for us.

Then, leave the graphic environment, go to the PLOT menu, select plot type
PARAMETRIC, give 'LINESCAT' STEQ, go to the PLOTR menu, set the resolution
to 1, and press DRAW.

That's all!

For this to work, you need a very tiny equation LINESCAT.
The variable LINESCAT must contain:
'\GSDAT(X;\GSPAR(1))+\GSDAT(X;\GSPAR(2))*i'

Is this simple, or what?

[Of course, \GS above means the Greek Sigma "ä" character.  -jkh-]
