I am putting together an FAQ for GNUPLOT.  This will address this question.
I hope to have something available soon.  Questions on here are very useful 
in showing what is needed.

many thanks to all the people who have replied and it's obvious now
that i need to set parametric. now, i have tried to get the plot
coords in the usual convention, i.e.

			| Z
			|
			|
		    |
			|
			-------------- X
           /
          /
         /
        /
       /
      /
     Y

i have tried to play with the set view and set ranges (individual x
y and z range). also, played with the order of the data columns in
the data file. but it seems that i still cannot get this rather, i
thought, simple view of the coords. any help? 

regards,

Sean

Subject: Hidden3d and countours

 when plotting surface plots I have need to have the countour lines
appear on both the surface and grid sections of the plot. I set it
with:
      set countour both
and this works until I get rid of the hidden surfaces with:
      set hidden3d.

When I do that the countour lines vanish form the surface itself and
are left only on the x-y plane.

Any hints?

If many of you use pure latex picture output from gnuplot,
you know that it's easy to exceed TeX's limits.  I was
just perusing some output just now, and I noticed many
repeated items (same object, same size, same coordinates).

This suggests to me that:
 1. there's a buglet somewhere in the latex driver
 2. you may get more latex out of gnuplot if you run
    your output through 'sort | uniq' (for non-unix folk,
    these means "deleted repeated lines in the file"). Of
    course, you would have to mv your \begin{picture}
    and other statements back to their proper place
    after sorting.

You have data file in the form:

x1	y1	z1
x2	y2	z2
..

right?

you have to 'set parametric' first.

The current practice for creating a "printable" file is to say

set output 'foo.out'
set terminal postscript
replot

Note that Jeff Norden has developed a lot of neat patches in the
past that we might discuss further.  One of his was a method to
mix interactive screen graphic activities with printing activities:

set printer terminal_type
print   (with no arguments)

Thus the command plot would stay on the screen and print would send
the last plot or splot (by doing a replot) to the printer.  He allowed 
print with arguments to remain backward compatible.  I've incorporated 
his patches in some of the earlier gnuplots (up to 3.1 I believe) and 
found them quite useful.  

Jeff, are you around any more?  Have you found this news group?  Do
you want to discuss some of these changes in hopes of making them
mainstream?  (His real innovation is in expression parsing--but that's
grist for another posting!)

P.S. How exciting to see this news group become a reality!  
     Viva la newsgroup!

This doesn't exactly answer your question, but with the epsf.tex macro file,
you can put

\def\epsfsize#1#2{.5\hsize}
\hbox{\epsfbox{fig1.ps}\epsfbox{fig2.ps}}

in your latex source to get fig1 and fig2 side by side.

Try using eepic or epic. They reduce the amount of output that gnuplot
generates and put a lot of the work to the dvi converter rather that TeX
itself.

Subject: Some substantial extensions to gnuplot
Organization: University of British Columbia, Vancouver, B.C., Canada
Date: Sun, 4 Oct 1992 18:01:10 GMT

I've been using a version of gnuplot as an interactive
shell for a family of ecological simulation models.

In the process of doing this, I have made a number
of extensions and modifications, some of which
might be of interest, which I'll describe in no
particular order here.

1) String variables with command line interpolation.

   i.e. foo = "some tedious to type token sequence"
	plot $foo

   It would be easy to add the <strings.h> functions
   as internal gnuplot functions, but I have not
   needed to so far.

2) A complete re-write of the scanner and tokeniser.
   Input streams are treated as a ronly buffer
   manipulated with a handful of emacs-like primitives.
   This is intended to support future extensions to:

3) The interpreter. This has been extended so as to be
   to essentially C with only data types (INT DOUBLE CMPLX).
   
   It follows all the lexical rules of K&R2, supports 
   n-ary function definitions with local variables
   and all of the K&R control structures except
   switch/case.

   I have left the hard parts for someone else, or until
   I need them badly enough to figure out how to steal the
   pieces I need from gcc.

4) As part of independent work on a PC graphics system,
   I have some of the support needed for multiple 
   plots, each in an independent graphics state.
   
   > plot sin(x)
   > scale .5 .5
   > translate 100 80
   > replot

   looks pretty cool on my PC. Some major architecure problems remain,
   of course.

5) As part of another task, I have candidate data structures
   and primitives for histograms:
   
   a data source is filtered through a udf which assigns
   an index to each value, and then places the value
   in a dynamically sized and typed array. 

   What's missing is a command line interface to these
   primitives, and the plot side.


5) I'm also developing (very slowly) some GIS-like
   primitives for the display and editing of maps.


I'd be happy to discuss this with interested persons.
I'd also like to know if any parts of this stuff will
be duplicated in 3.3.

This is exacly right. Since we deal with two approximations (the hidden
line which is piecewise linear and the contours, another piecewise linear
approximation) interleaving each other, this is a difficult problem.
Maybe lifting the contours by some small epsilon toward the viewer will
do the trick.

A gridding program that uses natural neighbor interpolation, NNGRIDR,
is available commercially.  Send email to me (Dave Watson) for 
details.

Is there a trick I could use to get splot to do what NCAR srface does?
With hidden line removal, log/linear autoscaled axes, labels and arrows?

What should we do to quit receiving the mailing list, now that the
group has been created?  Is the mailing list just going to be closed?
Should we flood info-gnuplot-request with unsubscribe messages?

Put a blank line in the data file where each discontinuity goes.  This is
documented under 'plot data-file'.
