[comp.misc] GnuPlot Question, also about printing graphs in general

ajayshah@alhena.usc.edu (Ajay Shah) (04/25/91)

I have a set of (x, y) scatterplot data.  The x's are in no
particular order.  The x's are not integers.  E.g., the data 
might look like

2.2 2.6
1.1 3.4
1.1 7.2
2.31 7.9
7.2 19.1

(Notice two points with x = 1.1).  
I'd like to plot two kinds of pictures:

	- a dot for each (x,y) point
	- all (x,y) points connected by lines.


I couldn't get GnuPlot to do this; he felt hardcoded for plots
where the x changed in orderly fashion.  Is that correct, and can
I write off GnuPlot among my options?

What *are* my options?  I'd like as much flexibility on output
devices as possible, but EPSF is a necessity.  I can deal with
script-oriented application programs or C/Pascal libraryish source.

Thanks,

	-ans.

It's not at all clear that connecting lines between points on a
scatterplot is meaningful.  What information about the data would
you expect to obtain from such a plot?
