[Gnuplot-info] Placement of plot title

[Van L. B. <Ber...@ec...>]

Dear all,

I am constructing 2D figures containing several graphs. Each graphh has a title, but the title is placed in the right-upper corner of the figure. this is suitable for some of the figures but not for all, as in some cases, the graphs cross their titles. Is there a way to move these titles to the left-upper corner of the figure?

Thanks in advance,

Bert

[Gnuplot-info] query about interpolated pm3d map

[ravi t. <rkr...@gm...>]

Hi,

I have a data in a matrix form. I am using pm3d map for plotting my data. I
want a smoothly varying plot. Can you tell me is there any way gnuplot can
interpolate the intermediate values between two points and give me a smooth
curve.

Thank you very much.

[Gnuplot-info] Gridlines of different color

[mikpol <mik...@gm...>]

Hi Everyone,

I have manually set tics on the x and x2 axes using 'set xtics...' and 'set
x2tics...' commands. I would like to make the gridlines emanating from the
tics on x and x2 of different color. Does anybody know how I can accomplish
this?

Thanks in advance for any help.

-Mike

Re: [Gnuplot-info] autoscale in x1y1 and x1y2 axis

[Dieter J. <die...@t-...>]

Dear goffart,
I would try adjust both ranges to a symmetrical positive / negative range, 
otherwise I cannot see how to get where you want to get to:

set yrange [-100:100]
set y2range [ -1:1]

will give you the same "zero" in "graph" coordinates. But how can you expect 
the position of "zero" to be identical given that one range starts at zero 
whereas the other range starts at -100?

Say, Y = [ y_1:y_2 ] be the range of y-values you use, Y2 = [ y2_1:y2_2 ] be 
the range of y2-values you use, then "0" will be at the same "graph" position 
if:
- 0 is within y_1, y_2 and y2_1, y2_2, respectively and
- y_2/y_1 = y2_2/y2_1
hope this helps,
or I got you entirely wrong,
take care

Write that expression properly, in something reading more like a 
programming language rather than typical mathematical shorthand 
notation, and it'll just work:

	plot y**2-5*x+6

To see why this works, read "help plot" and "help expressions", thoroughly.

And you think 3.7 didn't?  Wow, that must be a serious case of selective 
perception ;-)

Then don't trust your eyes so easily.

Whatever makes you think that gnuplot-3.7 would have magically changed 
its behaviour regarding X11 acceptability now, 8.5 years after its 
freeze-and-release?  Or even _could_ have, had we wanted to do such a 
thing back then?

> How do I get the  plot to display on the terminal screen?

Compile gnuplot with all the necessary libraries in place.

Re: [Gnuplot-info] plotting polynomials

[H. G. A. <as...@gm...>]

Hi!

Try with:

gnuplot> plot (x**2 - 5.0 * x + 6.0) with lines

or

gnuplot> f(x) = x**2 - 5.0 * x + 6.0
gnuplot> plot f(x) with lines

For further examples see

gnuplot> help plot

It usually is.  If it fails in your case, it must have something to do 
with how exactly you set things up.  It'll be impossible to say more 
without you showing a reproducible example.  For starters

gnuplot> set multiplot layout 2,2
multiplot> splot x
multiplot> splot y
multiplot> splot x*y
multiplot> splot sin(x)+y
multiplot> unset multiplot

works just fine here, in gnuplot-4.2 pl 3.

See "help set decimalsign", look for the 'locale' option.  If you 
gnuplot doesn't have that, update.

[Gnuplot-info] Several plots with extra key

[Roman K. <ma...@ro...>]

Hi,

I plot several similar plots, include them separatly in LaTeX and would 
like to put the key into the caption of the figure.

The question: Is it possible to output only the key in gnuplot without 
the actual graph?

Thanks,
Roman

gnuplot is not a general-purpose 3D engine, it's a plotting program.  As 
such, it always does parallel projection.

Re: [Gnuplot-info] Can't get labeling via xtics to work

[Thomas S. <t.s...@fz...>]

some remarks:

there's no need to specify xrange in seconds,
use the time format of the data instead:

#set timefmt "%s"
#set xrange ["1206853200":]
set timefmt "%B %d %Y"
set xrange ["April 1 2008":*]

your xtics are far off the axis range - all at the position of "January 01
2000"
(insert a 'show xrange' line into your current script file and you will see
it).
this works:

set xtics ( "7.1.0 Release" "April 7 2008" ,"April 14 2008","April 21
2008","April 28 2008","May 5 2008","May 13 2008","May 20 2008","May 27
2008","June 3 2008")

even when plotting time data each string separated by space, tab, ...
counts,
that means that for a data file like this
April 7 2008, 15, 61, -24, 0, 0, 0, 0
plotting the 2nd value (here: '15') vs. time needs a command
like this: plot .... us 1:4
and not 'us 1:2'

with the above changes i got a nice plot using the following command:
plot "/tmp/condor-nmiplots-cYynkG.data" using 1:5 with boxes ls 5 title
"Good Downloads", "" using 1:4 with boxes ls 9 title "Good Source
Downloads", "" using 1:6 with boxes ls 7 title "Bad Downloads", "" using 1:7
with boxes ls 3 title "Good Downloads/20", "" using 1:8 with boxes ls 8
title "Bad Downloads/20", "" using 1:9 with boxes ls 1 title "Good
Downloads/200", "" using 1:10 with boxes ls 2 title "Bad Downloads/200"

more information you will get when reading the manual or the
output of the commands:
help timefmt
help time/date
help xtics
help datafile

[Gnuplot-info] Can't get labeling via xtics to work

[Bill T. <bt...@cs...>]

I have this limited data set with the last 2 sets of numbers a don't 
care anymore.

April 7 2008, 15, 61, -24, 0, 0, 0, 0
April 14 2008, 12, 59, -10, 0, 0, 0, 0
April 21 2008, 17, 75, -8, 0, 0, 0, 0
April 28 2008, 21, 89, -6, 0, 0, 0, 0
May 5 2008, 14, 81, -0, 0, 0, 0, 0
May 13 2008, 17, 119, -0, 0, 0, 0, 0
May 20 2008, 17, 115, -0, 0, 0, 0, 0

June 3 2008, 11, 88, -0, 0, 0, 0, 0

This is the plot setup which no longer has any a-axis labels
and it is probably something simple.

[Gnuplot-info] Multiplot combined with splot command

[Tatjana S. <sk...@si...>]

Dear all,

Please, if someone could tell me if it is possible to make a multiplot
that consist of several graphs obtained with splot command. In practice
I need several basically 2d plots on the same page, but each of which
are splots with no surface options, that is just contours. When I try with
usual multiplot procedure with set size x,y I obtain 2 graphs on 2 pages 
instead 2 graphs on 1 page. Is the problem coming from the fact that I am 
not able to define z dimension of the graph as being 0?

Thank you very, very much in ad¬vanc,
Best regards, Tatjana

[Gnuplot-info] Can't get labeling via xtics to work

[madcitybt <bt...@cs...>]

I have this limited data set with the last 2 sets of numbers a don't care
anymore.

April 7 2008, 15, 61, -24, 0, 0, 0, 0
April 14 2008, 12, 59, -10, 0, 0, 0, 0
April 21 2008, 17, 75, -8, 0, 0, 0, 0
April 28 2008, 21, 89, -6, 0, 0, 0, 0
May 5 2008, 14, 81, -0, 0, 0, 0, 0
May 13 2008, 17, 119, -0, 0, 0, 0, 0
May 20 2008, 17, 115, -0, 0, 0, 0, 0
May 27 2008, 7, 85, -0, 0, 0, 0, 0
June 3 2008, 11, 88, -0, 0, 0, 0, 0

This is the plot setup which no longer has any a-axis labels
and it is probably something simple.

[Gnuplot-info] graphing for mechanical applications

[Mike L. <eh...@ho...>]

Gentlemen,
 
Thank you very much for your wonderful gnuplot program.
 
Is it possible to set xtics and ytics to exactly the same lengths say a cm. or inch,  and then make a print of it without any compressions or elongations?
 
The "set square" command doesn't seem to work.
 
Thanks,
 
Mike Libby

Re: [Gnuplot-info] gnuplot script aide

[Thomas S. <t.s...@fz...>]

try this script (works here without problems):

#!/bin/bash
filelist=`ls -1 *.txt`
for fname in $filelist ; do
echo $fname
gnuplot << EOF
set term png
set out "$fname.png"
set autoscale
unset label
set title "COMMUNICATIONS"
plot '$fname' using :5  w impulses
EOF
done

and this is my script 
#!/bin/bash
filelist='ls -l *.txt'
for fname in filelist ; do
gnuplot << \EOF
set term png color
set out "$fname.png"
set autoscale
unset label
set title "COMMUNICATIONS"
plot '$fname' using :5  w impulses
EOF
done

i think it doesn't care the "for"  or the fname variable  

thanks

could you post one of your datafiles (or a few lines
of it, if it's too large) as an example?

maybe you should choose another filename for the
output file, other than the name of the input file...
actually you are overwriting the input file.
