The attachment didn't make it --- but you already know that.

I suggest you go to the Bug Tracker at SourceForge and submit this
there. You should be able to attach your example there. In case of
doubt, try to reduce your problem to the absolute bare minimum and post
it as text.

Hi Henry,

I had a similar problem like you. I figured out that gnuplot overwrites
the output file (in your case "plot.ps") with an empty postscript file
if you don't set output again before replot!
That means:

set term postscript
set output "plot.ps"
replot
!lp plot.ps
set output
set term x11
replot

That must solve your problem!

Regards,
Bernd

You should

	unset output

at this point.  That closes the output file --- and among other things, 
writes the 'showpage' you were missing.

History doesn't get erased --- commands from loaded scripts just never 
get added to it in the first place.

No.  The behaviour you observe is a bug, which I think was fixed around 
the time of the 4.0 release.  You're not by any chance using a pre-4.0 
binary, are you?  If so, I strongly suggest you update immediately, or 
wait a little longer for the upcoming 4.2.

Hi Reza,
'help set terminal'
on a gnuplot-commandline ought to be your friend ....
Moreover, 'help set output' will tell you how to get those data into files =
so=20
you can further process them.
man gnuplot isn't too bad, either.

Take care



Dieter

How can I find that I have X11 in my LINUX?
Could you please  explain  how can I installing the binary RPM?

When I eg.  try
set term  tgif
plot sin(x)

i get lines like this:


.....
poly('black',5,[
        119,648,971,648,971,70,119,70,119,648],0,2,1,70,0,0,0,0,8,3,0,[
]).




Thanks
Reza

That's almost certainly not what you want to get at that point. Your
build failed to get X11 support. Odds are you'ld have fared better
installing the binary RPM instead of building your own.

It's almost impossible to help you with that if you don't tell us what 
exactly you tried, and what was "not graphical" about the result.

RTFM.  'help set terminal' and 'help set output', in particular.

If you don't know you do, you have it.  But that's not your problem. 
The problem is that you built your own gnuplot, but failed to install 
enough of the other packages first so the build of gnuplot could work 
well.  In particular, you're missing the "development" part of the X11 
installation.

> Could you please  explain  how can I installing the binary RPM?

This is not the place to get problems with basic use of a Linux 
distribution solved.  Frankly, if you can't manage to install RPM's off 
your CDs, building your own gnuplot is beyond your skills.

Of course you do, for two reasons:

1) There's one 't' too many in those commands you tried, which rather 
directly prevents it from generating GIF files.

2) You went back to try-and-error immediately after reading 'help set 
term', but didn't bother to read 'help set output', too, as you had been 
told to.

But the real problem is probably elsewhere: just as you don't have X11 
development installed, you almost certainly don't have any GIF-writing 
development packages installed either.

As far as commanding the program is concerned: absolutely.

But we're talking about a plotting program here, i.e. its major purpo=
se=20
is to create exactly the type of output that people with a visual=

handicap won't be able to make much use of.

So, to sum it up: the functionality is accessible just fine --- but=

still not really usable.

No.  But usually, this can be avoided by choosing a less strange font.
gnuplot does try to avoid this problem, but if it's wrongly informed (or 
has to guess, and gets it wrong) about the the font's actual size, all 
kinds of bad things can happen.  Pick a fixed-width font, and use a 
terminal where gnuplot has a realistic chance of actually *knowing* how 
big the font is.

See 'help ztics' and what it points you to.

Well, maybe you shouldn't have 'set ticslevel 0' then...
