It is preferred to produce a set of "diffs" between your version and
the latest release.  I would strongly encourage you to do this and to
submit your diffs for possible inclusion in a future version of the
official release.  It is not against the "tradition" of Gunplot to allow
certain drivers to have extensions -- the LaTeX driver, for example,
enables a technique whereby more than one line can be inlcuded in the
title.

I appreciate the work of those that port programs to different
environments, but may I ask exactly what is the point of porting
gnuplot to MS-Windows if it is still limited to 64K like the DOS version?

Here I sit with a new DX2 and 8MB of RAM thinking I would no longer
have to upload large files to the SPARC and use X11 gnuplot and up
pops the old DOS line. Well, nice try but I guess it's back to the 
UNIX world for me.

Subject: gnuplot_x11
Summary: "Enhancement" for x11 driver
Organization: The Ohio State University
Date: Thu, 8 Oct 1992 19:15:10 GMT

Pursuant to an earlier posting (by me) I have modified gnuplot_x11 --
the outboard terminal driver -- to allow the graphics window to
remain after gnuplot exits (or sets term to something else).  The
idea is (a) to keep as many graphs as you want around for comparisons
or (b) to allow programs to generate graphs with arbitrary elaborate
formatting by spawning gnuplot.  This is better than xplot, because
the graphs can be resized.

My patch has only been tested in version 3.2.  I modify two source
files, gnuplot_x11.c and term/x11.trm as shown in the output from
diff at the end of this posting.  When everything is recompiled,
gnuplot accepts the command-line flag "-fork".  If this flag is
set, then the x11 driver will fork off and become independent when
it receives the terminate command.

I find this useful and robust, but I admit that I don't really know
what I am doing in this sort of programming.  I offer these changes
for use or comment, without the slightest guarantee.

Date: 15 Oct 92 10:57:13 GMT

When I tried to load this file in gnuplot v. 3.2 in ms-dos
(my first try with gnuplot):

set view 0,0,1
set contour base
set nosurface
set noparametric
splot  100*((y-(x*x))**2) + ((1-x)**2)
pause -1 "Hit return to continue "

I got divide by zero (or was it floating overflow). I tried
this on a Sun-workstation, and there it ran fine. Then I
bought a 80287 math coprocessor to my PC, installed it today,
and now I get "Floating point error: domain. Abnormal program
termination".

My -.exe is from nic.funet.fi, file gnuplt32.zip.

Is there anoybody out there, who can run this in ms-dos, 80286 
+ 80287? What's the trick?  Should I try another .exe-version, 
and where can I get it (I can't compile myself)? I get pictures 
from all the demos that were in the distribution fine (except 
Ackermann's function, but that's due to the limited stack in ms-dos).

You should change the Makefile to have '-DSGTTY' included among the CFLAGS.
I am hoping that your STARDENT does have the file sgtty.h somewhere.

   Use "set term latex".  Physicists are also "*real* big" on LaTeX.

I would recommend using 'set term postscript' plus 'psfrag' style
file, written by Craig Barratt (craig@isl.stanford.edu). In gnuplot
one would use straight ASCII labels, e.g., sin(x):

      \psfrag{sin(x)}[br][br]{$\sin(\theta)$}

The psfrag macro will then substitute LaTeX text for the
original label. This has the advangage of allowing arbitrary
orientation of the text, at the expense of being slightly less
WYSIWYG, and requiring one more step in preparing the document.
But then, LaTeX isn't WYSIWYG, either.


I use Postscript graphs rather than LaTeX graphs because a) they
somehow look better on the printers we have and b) all non-textual
material is in the same form (postscript)

In my humble opinion, one way of achieving this is to add some more
programmability features which will enable the user to

1. implement conditional branches 
2. create arrays
3. replace functions by procedures with an arbitrary number of arguments
4. write and use string functions, create string variables
5. create and use macros
6. consequently avoid repetitive calculation of
   identical subexpressions such as sin(u) in the following example,
   by using variables with shared scope:

 set parametric
 splot [0:pi] [0:2*pi] sin(u)*cos(v),sin(u)*sin(v),cos(u)

I do not know exactly how Gnuplot interprets multiple occurrences of
subexpressions inside a single plot or splot command,
but if it is calculating a subexpression each time it is encountered,
a new capability of using temporary variables to convey calculated results
between parts of a plotting command instead of repeating the subexpression
would eliminate unnecessary computations and possibly increase speed.

If such programmability features are added, then Gnuplot can also be
used for analysis and filtering of data, such as taking moving averages,
and "thinning". It can even be used to generate sequences of superimposed
plots of the same function with different parameters where those
parameters are calculated from within gnuplot, until certain conditions
are satisfied.

All this would require only a slight increase in the
programming effort by the user, and the gain in functionality
would be comparatively large.

The Unix utility `grap' has such capabilities but it does not
have an interactive user interface and generates output only in the
`pic' language, which is good for typesetting purposes only.

I hope the "authorities" see the best parts of both worlds
and put them together soon.

Yours respectfully,

What I have done is make up a simple gnuplot command file that prints the

It is executed with a simple "load 'gprint'" at the gnuplot prompt.
The file 'gprint' contains:

set terminal postscript

replot
!lp junk.ps
set output
set terminal X11
replot

It works for me.....

I think I may have too brief here to be understood, I think using

command.  *In addition*, I would like to be able to plot data
coming *from* a command.  It would seem a natural notation for this
would be

plot "command args|" ...

This way one could write a data massager, or a function value generator,
in C, or awk, or fortran, or whatever, and be able to easily use it
from within gnuplot.  I guess this wouldn't be portable to an MS-DOS
version, and might not make much sense in VMS, but it would be great
in Un*x.

I thought Piotr had migrated pretty far away from gnuplot at about version
2.0 or there abouts.  I know we discussed gplotlib at one point and he
showed me fchart and posted a few notes about it to the info-gnuplot
list over two years ago.  I wasn't sure how far it had spread and I don't
know what it's state is now.  I got the impression he was done with his
public domain effort and further development was related to his real
job, but I could be wrong.  Piotr?

Is it time to bring some of these lost programs back into the gnuplot
fold?  Does anyone have a list of gnuplot related programs worthy of
including on an archive site along side (if not inside) the gnuplot
program?  I remember Dave Kotz frequently posts how to acquire a
shareware package--and people have posted script files.  What's out
there these days?

Doesn't set xrange and set yrange make the scales the same for both
plots?  Or are you talking about the fact that the aspect ratio may
not be 1:1 on your viewing device?  If this is the problem then you
have some control over aspect ratio with the "set offsets" command.

As to a circular border--you might try cheating.  Turn off the border
(I believe this is set noborder) and then plot a circle of the desired
radius (plot 5).  You can also do a "set nokey" if you don't want this
last plot to show up in the key.  You won't get exactly the border line
type on some devices, but it may still be acceptable for your needs.

I am not in a place to check the commands "set noborder" and "set nokey".
If there are not right then I apologize--the functional equivalents
should be in the manual or the help pages somewhere...

NNTP-Posting-Host: jaeger.geog.ubc.ca
Summary: can do, but some design decisions pending

Yes, I'm out here, Mr. Moss.

I have code providing low level support for multiple plots.
Drawing commands are transformed through a PostScript-ish
CTM so that they can be scaled and translated (no rotation)
transparently.
I have only modified the EGA/VGA terminal driver so far, 
but the modifications for most other devices should be straightforward;
the scaling/translation routines are device independent.

The difficulty is in providing command line syntax to get at this
feature, and in putting a layer of indirection between plot
generation and plot display.

I envisage something like
 
> {foo = } display {n,m} "label" {
  plot 1,1 
  .
  .
  .
  plot n,m
>}
>redisplay foo

The problem is, I am using gnuplot as a test-bed for several
delvelopment ideas which I work on very sporadically, and which are
not cleanly separated. These include a greatly enhanced interpreter,
and an completly new "scanner".

If enough people are interested in this approach to multiple plots
I could maybe cobble together a working version of the display command
mentioned above, and let people try it out, or at least make the
code I have available. (I'm supposed to be doing a PhD, not fun
hacks.)

As I see it, the main design decision is:

      should do_plot(), do_3dplot() and friends do the actual drawing,
      or should they generate a script which the display command
      could execute under the CTM?

or
      should the display code work with struct surface_points
      and/or struct curve_points directly.

I tend to favour the first option as being more general and providing
a basis for future extensions (e.g. dynamic resizing and relocation of
objects in a display structure inside a windowing environment). 
OTOH the second would be much easier to hack into place.

I think some comment from the "official" maintainers would be in order.

BTW, I think gnuplot is already a terrific piece
of software. If the development community now emerging makes the
right choices, we could give a lot of commercial products a 
run for their money.

The hidden line method used in 3.3 is different from 3.2.
All versions of MS-Windows (which are alpha test versions) do not
work with hidden lines due to a lack of memory.
The problem is known and should be fixed in later versions.

Other people have mentioned problems with the pause dialog box.
This is now slaved off the root window so you can resize the
graphics and text windows while the pause dialog box is active.

	I just downloaded this windowsvertion myself. And it seems
to be the best vertion so far! I tried to run the "all.demo" file from a
previous vertion and I allmost made it through the "bivariat.dem" file (which
I haven't been able to run under MS-dos), but sadly ended with a general
application error after the first plot. An other "problem" is that the
"pause -1" command just gives you a popup button and the plot window itself
goes away and on my 486-33 8 MB this makes the plot-window impossible to see.

	It also seems that the windowsvertion is *much* faster than the
x11 vertion running on a hp 340 workstation.
