The latest test version (3.3) will compile with djgpp 1.08, but due
to the dummy definition of signal() in djgpp, floating point
exceptions TERMINATE gnuplot.  This is most annoying in the middle 
of a session and makes gnuplot/djgpp unusable at present.

When someone adds a decent signal() to djgpp, gnuplot/djgpp will 
be ready to go.

Dear info-gnuplot people,

i am running a VAX 11/730, VMS 4.3 (don't laugh) in the context of magnetic
resonance imaging research. I would like to use gnuplot for the visualization
of my experimental data. I do not have a C compiler, just FORTRAN.

My question : is it possible to receive/find an executable gnuplot.exe where-
ever in the world, ready to run under VMS 4.3 ?

I would greatly appreachiate any hints. Thank you in advance

One way to determine the contour levels used would be to follow the contour
plot with

set term table
set output "contours.tbl"
replot

The file should have the x,y,z coordinates of the contours drawn.

A later edition of the MS-Windows version will have control f the default 
window size, line types and colors. These changes were only made recently
so there will be a delay before this version becomes available.

Gnuplot does have a hidden line removal: set hidden.  However, it is only
supposed to work on data files that are not parametric, ie, the data file
is a single column of numbers (z), and the x and y values are taken to be
the indices.  Hidden line removal will supposedly not work for parametric
data sets, ie, plotting three columns of numbers.  However, I have gotten
it to work by doing the following (assume three columns of numbers, x:y:z):
	set hidden
	splot 'dataset' using 3
	set parametric
	splot 'dataset' using 1:2:3
I don't really know why this works, but it seems to trick gnuplot somehow.
I have only tried this on wgnuplot (windows), not on any unix machine

This is correct. do 'help datafile' for more.

Look at the way the glass.dat is plotted in contours.demo in the demo
directory. It is in parametric mode, and you can plot and contour
parametric functions/datafiles.

You will have to create the X & Y values (have 3 numbers,
corresponding to X, Y & Z, in every line of your data), and 
'set parametric'.

>Does anyone know of a way to rename the axis of a noparametric

If gnuplot is in noparametric mode, the X & Y axes are incremented
uniformly by 1 starting from zero, and this is not settable by the user.

Hope thats help,

Hi GNUPLOT developers,
 
I am Lars Hanke, student of physics at Dortmund University (FRG). I'm
working with GNUPLOT quite a time on an Amiga and from time to time on an
IBM clone. Well, it's fantastic.
 
But I unfortunately had to notice that x-errorbars and spline 
interpolation for data plots are not supported. Who cares? I own a
C-compiler and I implemented the missing features, as styles
`errorsquares`, `splines`, `csplines`, `bezier` and `sbezier`.
 
I adapted a GNUPLOT 3.0 patchlevel 1. Yesterday I got a PD disk which
included GNUPLOT 3.2. Unfortunately the archive was damaged, but the source
wasn't included anyhow. Well, what I want to ask for is; could you send me
the most recent source, so I will add my new features and mail it back to
you? Or are those features already implemented?
 
As I am not sure that I'll get my UUCP node working, I would be interested
in a FIDO connect, `cause the latter works perfectly. If all fails, we
could still try the old fashioned envelope.

Thank you for answering my question. Unfortunately, the gnuplot

option of 'set term table'. I looked for help file on 'set term', but

I have seen this question several times, so it might be a candidate for
FAQ.
	What you call locus is an implicit curve representation and gnuplot
does not support it explicitly... However you can draw this curve as follows.
Splot the explicit surface x**2 + y**2 - 1, and contour it at z = 0 (a
single contour at z = 0). 'set view 0,0' and 'set nosurface' will give
you the 2D plot of the contour you need without the surface.
	Mathematically speaking, an implicit object is the zero set of an
explicit object of one dimension up. An implicit curve is the zero set
of an explicit surface, and implicit surface is the zero set of an 
explicit hypersurface in 4d. Contouring is just constant sets of the
surface, and so the zero set of an explicit surface (=implicit curve)
is the contour at z = 0.

Here is a gnuplot script:

set contour
set cntrparam discrete 0 # may be off here 
set view 0,0
set nosurface
splot x**2 + y**2 - 1

The sane default is A4 everywhere. Thats what ISO standards are for,
and that is why national standards bodies such as ANSi and BSI
contribute to and adopt ISO standards.  Having the default as a local
papersize used in a single country is bizarre on a piece of software
designed for international use.

Of course, if there were some sensible way to set the paper size this
would not be a problem. Set size uses a scaling factor rather than an
absolute size, and the manual has a caveat not to increase the size.

It would be preferable to have commands like 

set size A5
set size 8 inch 11 inch
set size x mm y mm

and so on.

You could try

set size 1.033 1.063

which will scale from US letter size to standard A4. This might not
work if the PCL asks for US letter paper (and fails) as part of the
initialisation.

that outputs a LaTeX picture with embedded PostScript.  It was
requested by a few people that wanted nice LaTeX equations and
nice PostScript graphics.  The hack was pretty trival (take 1 part
latex.trm, 3 parts post.trm, mix to form pslatex.trm).  I embed
the PostScript using the '\special{"' and '\special{!' features
of dvips.  I don't know if other DVI to PostScript converts support
those specials or not.

So where do I submit the code for evaluation and merging into gnuplot?

A friend of mine is making some plots with GNUPLOT and is generally
quite happy about it.  But now she wants a circle she drew to come out
as a circle instead of an ellipse.

The question is: can one change the aspect ratio in gnuplot to make
x and y axes have the same scale? (or x y and z axes)
