[Gnuplot-info] gnuplot error ';' expected

[Dang, S. <s....@fz...>]

Hi everyone,

I have a script which returns me the following error:

"/home/siaufung/atat/glue/qe/example/Result/mapsrep.gnu", line 8: ';' expected


The script looks as follows (I have marked line 8):

set xlabel "concentration"
set ylabel "energy"
set title "Fitted Energies"
plot [0:1] \
'predstr.out' u 1:3 t "predicted" w p 2, \

set title "Fitted vs Calculated Energies"
set ylabel "predicted energy"
set xlabel "actual energy"
set nokey
plot \
'fit.out' u 2:3 w p 1,x
pause -1

This script has been generated automatically by a software package calles ATAT. I believe this is an issue related to the version of gnuplot I am using now, because at the time ATAT was developed, they were using older versions of it. Since I am no expert in gnuplot I have no idea what to modify.

Can somebody help me?

Many thanks.

Best, Siaufung Dang

How can I make it so that the first tick, end left edge of the plot is 
aligned to the first data element 133.198 - sorry if my last question 
wasn't clearer.

See "help plot" and learn about your options, "title" in particular.

> 2.  the entire plot seems to be shifted.

I don't think so.  The left edge of your data is quite exactly where 
133.198 e6 should be on that scale.  So: nothing shifted.

Yes, they are.  So what?

Re: [Gnuplot-info] got c program to plot gnuplot.

[<ke...@ne...>]

On my linux system,
make test, make all, and make test/example  did not work for me:-(
On all other company software "make" fails about 75% of the time.
 "Cmake" fails 99% of the time. Just another layer of code that can go wrong and it dose!
 ./confiure&&make&&make install work 99% of the time.
 My system package installer and sudo apt-get work 88% of the time.


  I am so glad that in the doc they put the compile command. Most
of the time i have to go through failed make file and find all of stuff
i need to compile a program from the command line.


   Cheers kommrad,

hi keghn,
nice find, you can simple do:
make tests

NTL it works, but its not a library but an object file that you
can use in your programms.

[Gnuplot-info] labels and data offset

[howudodat <pe...@ho...>]

I am having two issues with my spectrum plot.  (visible at:
http://imagebin.org/280352)
1.  the plot command is being added to the graph as a label.  How can I
disable that?
2.  the entire plot seems to be shifted.  the xtics seem to be rounded with
the tics being: 133.180 E6, 133.200, 133.220, 133.240, 133.260, 133.280,
133.300 E6

and thus the plot "appears" to be shifted in the graph, the first line being
at 133.198
here is the plot command:

    set output filename.'-spectrum.png'
    set title titlename."-spectrum"
    set format x "%.0s e%S"
    set format y "%.0f"
    set ylabel "time (secs)"
    set xlabel "frequency"
    set xrange[*:*] noreverse
    plot filename.'.csv' nonuniform matrix using 2:1:3 with image

 Wow a c library that generates gnuplot plots!


 Hello.
 I got the example.c working on my Mint 14 mate 64 bit Linux system to work.
 I down loaded the tar and uncompressed  it into my home directory.
 Did not have to cmake, make, or ./configure&&make&&sudo make install.
 I just change to "home/keghn/gnuplot_i/test/" and type this in the
terminal:

gcc example.c -I. ../src/gnuplot_i.c -o example

ran it with:

./example

 And in the "example.c" had to change few lines:

//#include "gnuplot_i.h"
#include "../src/gnuplot_i.h"

  Thanks all
     Cheers
        keghn

Re: [Gnuplot-info] Title doesn't fit in the key box

[Geraldo R. <gfs...@gm...>]

Hi walter,

PNG terminal is not affected. I tried to change font size and scale in
cairolatex terminal but it doesn't give the desired result when I compile
my thesis. The legend doesn't fit in the key box. I also tried to change
key font but it doesn't work either. But I tried nothing with key margins.

gnuplot documentation says that:

*When using the TeX or other terminal where formatting information is
embedded in the string, gnuplot can only estimate the correctly exact width
of the string for key positioning.*

I would like to find a way to improve this estimative, because it's not
working for me.

Re: [Gnuplot-info] Gnuplot Summed y Values over an Interval

[Vesnog <ong...@gm...>]

Thanks for your answers, I will try the methods mentioned. By the way I
already have a file of z[i] vs. PDF_Gaussian as two columns. My intention is
to plot the histogram of the resulting Gaussian which is not evenly spaced
since the argument of the Gaussian is not evenly spaced.

How about:

total=0; ssq=0; sum=0;
stat(y) = (total=total+1, ssq=y**2+ssq, sum=y+sum);
mean(x) = sum/(1.0*total);
mlvar(x) = ssq/(1.0*total) - mean(1)**2;

plot [0:5] '-' using 1:(stat($2)) notitle
0 0
1 1
2 2
3 3
4 4
e

The plot command loops over the data set, and stat computes the total
number of data points, and running sum and sum of squares; it returns
the running sum.

mean and mlvar do what they say they do.

an example:
we use a simple random generator producing something
like a normal distribution and write the numbers to
a file:

gnuplot> set print 'ts.dat'
gnuplot> do for [i=0:10000] {print
(rand(0)*2.-1.)+(rand(0)*2.-1.)+(rand(0)*2.-1.)}
gnuplot> unset print

we may plot the density function of these numbers by
binning the data and using the 'smooth frequency'
option of the plot command (to give all numbers the
same weight we set the y-value to 1.):

we now have a nice distribution in our plot canvas but
to use these data points we need to write them into a
file:

gnuplot> set table 'ts.tab'
gnuplot> replot
gnuplot> unset table

this file we use for plotting the distribution:

gnuplot> plot 'ts.tab' with linespoints

or for fitting a gaussian function to it:

gnuplot> gauss(x,a,x0,sigma)=a/(sigma*sqrt(2.*pi))*exp(-(x-x0)**2/(2.*sigma**2))
gnuplot> fit gauss(x,a,x0,sigma) 'ts.tab' via a, x0, sigma
gnuplot> plot 'ts.tab' with linespoints, gauss(x,a,x0,sigma)

that's all.

[Gnuplot-info] Gnuplot Summed y Values over an Interval

[Vesnog <ong...@gm...>]

Greetings, 

My purpose is to plot x vs. summed y values over a certain x interval. How
can I do so? Later I will calculate the mean, variance and median of the
data from this plot. I think it should be possible in Gnuplot someway. Any
help and suggestion is welcome and appreciated. 

P.S: I have a RNG and the random numbers generated are given as an argument
to Gaussian PDF, my aim is to find the mean, variance and median from this
accumulated data.

[Gnuplot-info] How to get rid of the polar axis

[Pu Ke <kd...@gm...>]

Hi all,
         I would like to remove the polar axis(that bold horizontal 
line), but do not know how to do it.  I recently update the version from 
4.4 to 4.6, it seems the polar axis is a new feature. Do I need to fall 
back to earlier version?
         I am sorry for the naive question, I am new to gnuplot. Thank you !

Oh, please.  Okay, I'll try again:

Sure, the two styles of calling produce different internal state -- but do they ever produce different plot output for the current plot (disregarding any additional commands sent later)?

It answered the question you asked.  Not my fault if that wasn't the 
question actually wanted to ask.

That depends entirely on what your _next_ plot command looks like.

That doesn't actually answer my question.  Sure, the two styles of calling produce different internal state -- but do they ever produce different plot output?

Yes.  Just "show xrange" after each of those to see for yourself.

To answer such questions, you can always "save" the state of gnuplot to 
a file after such a command in a fresh, interactive session, and compare 
the resulting files.

[Gnuplot-info] Two formats for axis ranging -- any difference?

[Craig D. <def...@bo...>]

Is there a functional difference between these two cases?

   set xrange [0:10]
   plot '-' using 1 notitle with lines

and 

   plot [0:10] '-' using 1 notitle with lines

More generally, is there ever a reason one would want to use one vs. the other?  Currently the Perl module PDL::Graphics::Gnuplot supports syntax to generate either of those case, but it would simplify the syntax and the API if we didn't have to keep both of those cases.

[Gnuplot-info] Data structure

[Bo J. <li...@f7...>]

Hi all,

I would like some advise to how to structure data in the best way.

I need to make plots containing spectra as function of temperature
(as the one shown on : 
http://glass.ruc.dk/data/data/J_Chem_Phys_139_101101_data/126HT/126HT.png )

I have all data in Matlab and normally makes specialized output files 
for the final print quality plotting in gnuplot.
However, how do I structure this kind of data?

I would like if the plotting script automatically loop over the spectra 
(the number of spectra could be written to a file if needed) and for 
each spectrum
* The line style should change (in a controlled manner)
* The title/legend should automatically be read and added.
* On some plots labels should be added, which should also be read from a 
file.

An alternative would be to make Matlab output the plot lines, and in 
this way performing the loop.

Best
     Bo

The location can be changed, though.  See "help set timestamp".

But note that the latter two are not dynamic, i.e. the command has to be 
run again before every plot to make sure you have the correct timestamp, 
particularly if you have not just the date, but also the time in there.
