[Gnuplot-info] gnuplot on LINUX redhat 9

[Ghoddousi-Fard, R. <c4...@un...>]

Hello,

I just installed  gnuplot-4.0.0 on LINUX REDHAT 9. 
After running I get:
Terminal type set to 'unknown'
I am able to change it using  'set term' to a list of available terminal types but none
of them( that I have tried so far) provide me any graphical result. Furthermore when I
exit and again run the gnuplot I get again "Terminal type set to 'unknown' ".
Could you please let me know how can I fix this problem in order to get graphical plots
and then save those as gif or JPG or ... files?

Thanks
Reza

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

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.

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

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.

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.
