add a

set output

after the second plot command,
otherwise the postscript file will not be written properly.

[Gnuplot-info] Problem with gnuplot - how do I get it to work

[<el...@ph...>]

Hello all Gnuplot people

I have a small problem that I dont know how to solve

I use my fortran code to generate a series of plotfiles and load files.

A typical loadfile ( n5-6c0901_J030.load ) looks like

plot "n5-6c0901.tcs" w l ,"n5-6c0901_J030.parsig" w l
set term post land color solid lw 2
set output "n5-6c0901_J030.ps"
plot "n5-6c0901.tcs" w l ,"n5-6c0901_J030.parsig" w l
set term x11

I run gnuplot version 4.0 patchlevel 0

as
gnuplot> load 'n5-6c0901_J030.load'
gnuplot> load 'n5-6c0901_J029.load'
gnuplot> load 'n5-6c0901_J028.load'

etc

When I want to use ggv, kghostview or print the *.ps files
I get errors.

I tseems now that I can only execute one loadfile at a time
and then I have to exit.

I have tried to add a line : exit at the end of each loadfile
bu that does not help.

Am I doing something stupid or ?

I want to be efficient and only write as little as possible since
I routinely need to p=E5rint these files as part of the analysis
of our studies.

There's not normally any need to do that.  You only get that message if 
gnuplot sees a specific need to open the plot window.  For a very simple 
example:

	echo "set term dumb ; plot x" | gnuplot

doesn't output any X11-related messages whatsoever.  If your plot script 
behaves differently, you'll have to show it to us for further analysis.

Of course.  Just don't use dgrid3d :-)

Do you really need dgrid3d to make your data grid-structured?

If your absolutely do need dgrid3d, see 'help table' for a method to run 
it as a separate process that writes the gridded data to a new file, so 
you can turn dgrid3d off again and plot the gridded data as mesh, 
combined with the original data as points.

Is your gnuplot script somehow trying to reset athe terminal to one that
uses xserver?

[Gnuplot-info] Plot points on grid

[Martin <ap...@ds...>]

Hello

I am using currently using some x, y, z data to generate a plot with a grid. I 
am doing this by setting dgrid3d which forms a grid based on the values of the 
x, y, z data and everything looks good. 

However, is it possible to show the x, y, z, plot points on the grid at all?

Thanks

Martin O'Shea.

It didn't run without warnings, though.  Your Linux installations lacks 
some installed packages for compiling programs that use X11 (called 
x11-devel or the likes).

See "help contour".  And "help splot datafile" about grid structure.

[Gnuplot-info] embedding gnuplot x window output into gtk

[ronnie_raj <kir...@ba...>]

Hello,
 I have been developing a GTK application and I am now using GnuPlot to
create some graphical output. 

 I was hoping to embed the gnuplot x window results into my GTK application.
So far I have been unable to do that can anyone give me any tips on how I
would go about this?

Thanks,

Kiran

Re: [Gnuplot-info] plotting 4 column data

[Ashenafi D. <ash...@gm...>]

Thankyou Hans,

I tried to do it but I couldn't get what I wanted. The plot u 1:2:3 will be
covered by the one u 1:2:4. By the way the values of column 3 vary between =
-
0.5 to 0.5 but that of column 4 lies b/n -1 and 1(the values actually are
very close to zero except for a fepoint where they could be close to -1 or
+1).

Am I missing something?

[Gnuplot-info] x11 terminal trouble...

[<van...@gm...>]

Hi, just a simple help request:

I installed/updated my 4.0 gnuplot to 4.2 in a SuSE 10.2 machine. Everythin=
g
was working fine with 4.0, and the installation 4.2 ran with no errors; but
when I use it I don't have anymore the pop-up windows showing the plots. Th=
e
default terminal is set to "unknown" and it does not recognize the "x11"
one:

set terminal x11

produces the following error mesage:

unknown or ambiguous terminal type

Besides, I do not have any trouble using other terminals to print the plots
into files, as "postscript" and the like (or at least not with the ones I'v=
e
tried).

What could be the problem with the x11 terminal (being that the one used fo=
r
the pop-up plot windows)?

How can I solve it?

Thank for your attention,
Iv=E1n.

[Gnuplot-info] Contouring in GnuPlot

[Martin O'S. <ap...@ds...>]

Hello 

I have a set of sample data as follows: 

CEMI (x) ggbs(y) FLOW MM (z) 

0.0        90.0     0 
6.5        58.7     166 
6.6        59.0     169 
7.3        65.0     141 
6.1        54.5     162 
8.5        76.2     217 
7.1        64.2     174 
6.0        54.2     209 
7.0        63.0     198 
7.6        68.3     171 

which produces a simple set of points on a 3D graph using splot. However, what 
I would like is to do is to interpolate between points to calculate the 
coordinates for a flow contour of, for example, 175 mm? 

Can anyone advise how I might do this? 

Thanks

[Gnuplot-info] 3D zooming in GNUPlot

[Daantje <d....@bn...>]

I can't seem to figuere out how to zoom a 3D graph. The right mouse button
doesn't work in the 3D graph. Is it possible to do this? If not then is it
possible to switch to a 2D graph with some command so that it is possible to
zoom???

[Gnuplot-info] plotting 4 column data

[Ashenafi D. <ash...@gm...>]

HI,

I have a problem plotting some 4-column data. The 1st and 2nd column are x-
and y-axes. The 3rd column has values which I used the 'set pm3d map' and
'set palette' to have different colors for different values. so basically I
can do a surface plot using the three columns, the 3rd column identified by
its color and not an axis. Now I want to put the values of the 4th column on
top of what I have. The values of the 4th column are mostly very close to
zero except for a couple of grid points on the x-y plane. If the 4th column
has a value different from zero, it will be, say, eithe -1 or +1. So what I
want to do is to put a circle or whatever symbol for points for which the
value of the 4th column is different from zero on top of the plot (which is
actually an splot) which I obtain from the first three columns. I think
there is a way to do it in gnuplot. Can someone help me out with that?

Many thanks,
Dadi
P.S. I'm using version 4.2 of gnuplot.

That's useless use of 'cat'.

	gnuplot >$OUT <<EOF

would work just as well, and without running yet another program.

The problem is not with gnuplot, but with csh.  You have to figure out 
what kind of quoting you need to get a literal '$' character into the 
text generated by the HERE script in csh.  Or, if you can't get that to 
work, see 'help column'.

Try 1:(\$2 + \$3) instead. That "$" symbol you are using is being
interpreted by your shell script. You need to escape that with "\" to
make your shell take that as simple text and gnuplot will then recognize it.

[Gnuplot-info] Calling gnuplot from csh shell

[Eduard <edu...@ya...>]

 Hi All,
 
I am a new user of Gnuplot and I have a basic question.
I want to write a script in csh (c shell) which takes some data from a file
named output.dat and sends it to gnuplot for plotting (a 2D plot). The
output.dat file has 3 columns -x,y,z. I am interested to plot (y+z) as a
function of x. What I did is the following:
________________________________________________________

#!/bin/csh

set IN  = ./output.dat
set OUT = ./output.eps
cat <<EOF | gnuplot > $OUT
set term postscript eps color
set origin 0.0,0.5
set size 0.5,0.5
plot "$IN" u 1:(2+3) title "p"  with lines
EOF
--------------------------------------------------------------------------------------
The bolded line is the one which make me  difficulties. I have tried to
replace the syntax from -> 1:(2+3) <-
with 1:($2+$3), 1:$(2+3), etc but without any success :(. 

If you could help me to fix this problem it would be really great.

With all the best wishes,
Ed
