A better way to do it would be to write the lines both times using 
some sort of "Exclusive Or" mode... where it adds the line's pixels
to the screen using XOr logic.  Then, just do exactly the same thing
again (ie call your same line-drawing routine) to REMOVE the line.

On a Macintosh at least, it was very easy to to specify the drawing 
mode and the system would do the logic for you.  I'm sure there must
be something equivalent on most other systems.

Actually, Playmation is Hash Enterprises.  We designed it, wrote it, and
own the code.  Cineplay Interactive is helping distribute it.  Cineplay
is the software arm of Will Vinton Enterprises.  Confused yet?  I know

    Polyhedron intersection has both trivial accept and trivial reject
conditions.  Let P and Q be two polyhedra, and let Pc and Qc be some
arbitrary "center" of the polyhedron.  Then let Prmin & Qrmin be the
minimum distance from the center to any of the vertices of the polyhedra,
and Prmax & Qrmax be the maximum distances from the polyhedra centers to any
vertex on the corresponding polyhedra.

    Trivial Reject:  |Pc - Qc| > (Prmax + Qrmax)

    Trivial Accept:  |Pc - Qc| < (Prmin + Qrmin)

    If neither of these tests succeed, then you must test each vertex of P
to see if it lies within Q, and then you have to test each vertex of Q to
determine if it lies within P.

    This is not all that simple for non-simple polyhedra (e.g. a torus), but
you may just be dealing with simple polyhedra anyway.

Subject: Problems with readline

Hello again!

We have a problem with gnuplot V3.2
We are running ISC SysV R3.2 and we have X11R4 Roells server.

There is  bug (?) in readline.c
--------

/* SIGTSTP defines job control */
/* if there is job control then we need termios.h instead of termio.h */

#ifdef SIGTSTP
#define TERMIOS  ---> causes wrong include
#endif


#ifndef MSDOS

/* UNIX specific stuff */
#ifdef TERMIOS
#include <termios.h>
static struct termios orig_termio, rl_termio;
#else
#include <termio.h>
static struct termio orig_termio, rl_termio;
#endif /* TERMIOS */

--------

On our system SIGTSTP is defined and therefor <termios.h> is included.
But in termios.h IUCLC and ONOCR are not defined.

I have fixed this by undef TERMIOS to cause the proper include.

Anyway, apart from that we have problems with readline.
( Actually we have problems with this function with EVERY gnuish software
i.e gdb ).
When we are using ^P to get the last command line we still get it but
it isn't echoed, so it is a bit like walking in the dark.

So, what is the right way for our system to get readline and
an updating plot window under X11?

Hi !

I have a sequence of the following pairs: [<date> <value>], where
<date> is expressed as the number of seconds elapsed since the
beginning of UNIX era (Jan 1 00:00 1970).  Dates are not continuous,
meaning that there's a gap between consecutive values of <date>.
How do I get normal-looking dates on the plot as range markings for
the "date" axis ?  Something like "Oct 1 10:15:34" instead of 74938183
(or, 75*10**6, rather) is what I need.  Is it at all possible ?  Your
help is very much appreciated.  Thanks.

P.S.  If it's impossible to do with GNUPLOT, maybe you know of some
      other graphics package that allows to do that together with
      being able to produce PostScript files with plots

Thanks for the response to this query, but I'm afraid that I wasn't clear in
expressing my requirements to David.  I need to generate multiple graphs or
plots per page.  That is, several plots stacked vertically on a page as shown

        0  1  2  3  4  5  6  7  8  9  10

Specifically, I need to create strip chart style plots and frequency response
(Bode) plots.  From what I've seen gnuplot can only create one plot/graph/grid
per page.  Is this correct?  Are there any plans to include provisions for
multiple plots/graphs/grids per page?  Thanks for your assistance.

I got my exe file but I had to make a few corections. Several of the
data files had no cr,lf (0A,0D), perhaps becouse of of the Unix

it possible to have larger data segments? I changed the stacksize in

The other option apart form using psfig is to include latex output directly
from gnuplot.  If you "set term latex" , "set output filename" where
the file name is in quotes and then plot your function. Gnuplot will generate
the latex code to plot the function in the file given by the output command.
You may then include this file into your latex document.  By placing the code
within a hbox you can shift the picture left or right. The command raisebox
will allow you to lift the second diagram to be beside the first.  
        A bit complex but still an alternative.

	Latex does take care of numbering figures automatically for you if
you include a caption and a reference label. ie

		\begin{figure}	
		 ...insert figure...
                \caption{This is my picture}
                \label{fred}
                \end{figure}

Then within your text you might have: See the diagram \ref{fred} on page 10
this might appear as : See the diagram figure 3.4 on page 10

 Latex will number you figures for you and match references in the text to the
correct figure.  Hope this has helped

ONe more question while were at it.
I finally figured out how to contour and surface mesh
2-d data. You have to put a blank line after each row
of data (which are specified one point per line in a long column)

However, you can not specify the x,y locations (i,e, parametric)
you must set noparmetric and list only the z values

The problem: I have data from a 40x40 grid which represents
an 80x80 domain (deltaX = 2). When I contour it up, I want the
axis to go from 0 to 80 but they only go from 0 to 40.

Does anyone know of a way to rename the axis of a noparametric
contour plot.  I.E. keep the plot the same, just rewrite the
axis lables?

Thanks

To whoever reads this message!

I have taken the above email address from the cover of the GNUPLOT 3.2 manual
in the hope that the recipiant can help me.

As part of my final year project here at Essex University, U.K. I am intending
on using Gnuplot to display various data that my 'C' program will produce.

What I would like to be able to do is execute Gnuplot from within my 'C' code
so that it can be used as an interactive part of the program bringing up a
Gnuplot window displaying any data set chosen by the user.

I am currently not sure if this is possible (although I have a few basic ideas)
so I would appreciate you telling me how to go about doing it (with some 
example code maybe).  I know there is a library routine system() which allows
commands to be executed as if they were typed from the shell.  When using this command and piping in a datafile, the Gnuplot window only appears very briefly
despite the use of 'pause -1' in the datafile.

I am currently using SUN SPARCstations running an X-window environment with
the UNIX operating system.

Thanking you in advance of your early reply.
