Plot problem?

[Robert T. Short]

And on that note.....

This may be a gnuplot problem.  I don't know.  I am running 4.2 (the 
current debian lenny gnuplot package).  I confess to being somewhat 
overwhelmed by the plot/graphics threads so this may have already been 
addressed.  If so, I apologize in advance.

The attached script is a vastly simplified version of something I do a 
lot of.  It draws circles with lines between them.

I frequently print to encapsulated PostScript or fig, depending on 
whether I further need to annotate the plot or not.

There are two problems: 'axis square' doesn't seem to work and line 
styles don't print correctly.

--- With either 'axis square' or 'axis equal', the axes come out unequal 
so the circles are smashed.

On my desktop with a standard monitor (1280x1024) the axes are ALMOST 
square.  On my laptop (wider in the x direction) the circles are visibly 
flatter.

The fig file comes out just exactly like the monitor display.  However, 
if I resize before printing so the axes appear square on the screen, the 
plot is redrawn & printed so the fig file still comes out flattened.

The eps file comes out with square axes.


--- The on-screen plot comes out with the line styles and colors 
specified.  The fig file cycles through the colors for both the circles 
and the lines.  The eps file gets the colors right, but not the line styles.


I could do this to a fig file in 2.9 by resizing then printing...


In MATLAB, I can't do fig files of course, but it gets the eps file 
right EXCEPT it loses all the colors....

Any suggestions?
