[Gnuplot-info] (no subject)

[Chiara <chi...@ho...>]

Hi,
i'm new in gnu plot.

I'm trying to plot the histogram produced by the command latency -g name_file of Xenomai, but I obtained this message:
"warning: skipping unreadable file "latency - gr", no data in plot.
I use the command 

gnuplot -e 'input_file="latency -g gr"; output_file="/path/gr.png"; graph_title="graph" ' /path/histo.gp

in according with the script histo.gp.

Can someone help me, please?

Thanks!

I am not near a running gp version but does 'set datafile separator "\t"' help?

[Gnuplot-info] missing data = empty string ?

[Theo <th...@gm...>]

Hi there,
I have data files with missing data.
e.g. the following TAB-separated file with 4 columns.

13.05.2013	0	1	16.4
14.05.2013	0		16.5
15.05.2013	0		16.2
16.05.2013	0		17
17.05.2013	0		16.6
18.05.2013	0	1	
19.05.2013	0	1	
20.05.2013	0	1	17.2
21.05.2013	0		16.8
22.05.2013	0		16.9
23.05.2013	0		16.9

If I want to plot column 4 gnuplot seems to plot only the data where 
there are 4 values in the row. If I want to plot column 3 it plots 
mostly data of column 4.
Since gnuplot has the option to define how it should handle missing data
I expected that

   set datafile missing ""    # empty string

will solve the issue. But it doesn't work.
   plot 'Data.dat' u 1:4 with lines
   plot 'Data.dat' u 1:($4) with lines
doesn't work either.
And 'help missing' doesn't help me further.
I do not want to change all the missing data to '?' or 'NaN'.
Any spreadsheet program manages to import correctly such data with empty 
fields. So I expected that gnuplot can also do it...
Any option that I missed?
Thanks, Theo.

Re: [Gnuplot-info] placing axis between tick marks

[Clement L. <the...@gm...>]

I don't know if there's an exact command for this, but by executing:

set xtics scale 0,1.0
set mxtics 2

before your plotting line, you make the major xtics 0 in size, the minor
xtics 1 in size, place one minor extic between every major xtic.

More information is in help set xtics, as usual.

[Gnuplot-info] placing axis between tick marks

[Mahmood N. <nt_...@ya...>]

Hi
In microsoft excel it is possible to change the position of axis from "On tick marks" to "Between tick marks" (http://peltiertech.com/images/2010-12/PositionAxisBar2007.png). 

I am looking for a similar option in gnuplot. Is there any?

Please let me now the correct option

Re: [Gnuplot-info] rotating tics

[Mahmood N. <nt_...@ya...>]

OK I found that the "right" option in 


  set xtics rotate by 45 right

will automatically do the job and there is no need for offset. Done!

set xtics rotate right rotate by 45

But the xtics go inside the chart (I want them to be outside). 

I played with different offsets, but could not reproduce as you see in the paper.
For example "offset -10,-1" moves xtics to some positions but by setting "offset -10,-2", I don't see any xtics! seems that they go outside of the chart area.

[Gnuplot-info] Announcing: Perl-Gnuplot interfaces PDL::Graphics::Gnuplot and Alien::Gnuplot

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

I have just released new versions of two Perl-gnuplot interface modules to the CPAN archive:

- Alien::Gnuplot - v1.010

Alien::Gnuplot handles configuration management and executable validation for gnuplot-using Perl modules.  Alien::Gnuplot works under POSIX environments and MSWin32 environments.  It verifies that a gnuplot executable is installed, and extracts its version and some configuration info into Perl global variables.  Alien::Gnuplot's development page is at "http://github.com/drzowie/Alien-Gnuplot".

- PDL::Graphics::Gnuplot - v2.000

PDL::Graphics::Gnuplot provides an object-oriented interface to gnuplot for scientific and common plotting using the Perl Data Language.  PDL::Graphics::Gnuplot objects each represent a single plotting interface and provide access to all the common Gnuplot modes directly from Perl and PDL variables. PDL::Graphics::Gnuplot's development page is at "http://github.com/drzowie/PDL-Graphics-Gnuplot".  Perl Data Language is a scientific-computing extension to Perl; for more information, visit "http://pdl.perl.org".

Happy hacking,
Craig

Re: [Gnuplot-info] xtics containing strings

[Theo <th...@gm...>]

in gnuplot type 'help xtics'
and have a look at the correct syntax

e.g.
set xtics ("abc" 0, "def"  1, "ghi" 2)
plot "points.txt" with boxes fill pattern 3

Plots red boxes with "abc" etc. as label.

hope that helps,
Theo.

Consider only the part of the command you ask about:

> plot 'data.dat' using 1:($4-sqrt($5)):($4+sqrt($5)) w filledcu notitle smooth csplines

There are 2 or 3 problems here.
One is fairly simple:

The "smooth csplines" must come immediately after the "using ...." part
of the command.  So you would need to move the "with filledcurve" to the end:

?  plot 'data.dat' using 1:($4-sqrt($5)):($4+sqrt($5)) smooth csplines w filledcu

However a bigger problem is that the "smooth" operation _replaces_ your
original data with a new curve defined by only an x value from the first
"using" column and a smoothed y value from the second "using" column.
The third "using" column is ignored, and no longer exists after the smoothing
operation.  This confuses the "with filledcurves" command, so we'll call it 
a bug that the program does not issue some error or warning message.

If you remove the third "using" column,  you'll see better what is happening:

? plot 'data.dat' using 1:($4-sqrt($5)) smooth csplines w filledcu

That command does give you a filled curve from the smoothed data,
but of course it's not quite the curve you wanted.

Possibly this two-part solution is acceptable:

  plot "data.dat" using 1:($4+sqrt($5)) smooth csplines w filledcu lc rgb "black", \
         "" using 1:($4-sqrt($5)) smooth csplines w filledcu lc rgb "white"

That wouldn't quite work in the general case, but it works in your case because
we know that y-sqrt(foo) is always less than y+sqrt(foo) so the second curve
is strictly less or equal to the first curve.

[Gnuplot-info] Smooth with filledcurves

[Brynolf <pat...@gm...>]

Hello, 

I want to use smoothing with the filledcurves plot, but I am unable to do
so. When I add smooth csplines to the command it will only consider the
first two columns and disregard the third column and plot a line, not two
lines with filled center, so to speak. Any help appreciated! My code:

set terminal pngcairo
set output 'plotData.png'
set style fill transparent solid .1 noborder

plot "data.dat" using 1:2 title "avg" smooth csplines lc rgbcolor "blue",\
	"" using 1:($2-sqrt($3)) notitle smooth csplines lc rgbcolor "blue",\
	"" using 1:($2+sqrt($3)) notitle smooth csplines lc rgbcolor "blue",\
	"" using 1:4 title "mag" smooth csplines ls 1 lc rgbcolor "red",\
	"" using 1:($4-sqrt($5)):($4+sqrt($5)) w filledcu notitle smooth csplines
lc rgbcolor "black"

Re: [Gnuplot-info] “block“ delimiter

I do not control the code that produces the data, and I think the code 
maintainers would not like to change a file format once it is established.

Of course I can change it myself in a post-processing step, but I wanted 
to know if gnuplot offers a more transparent solution.

[Gnuplot-info] “block“ delimiter

[Elias A. <eli...@gm...>]

I have a file that looks like this:

   bandindex:           1
   -0.21165  -0.36658   0.28144   0.00000 -24.30536
   -0.22193  -0.36065   0.28144   0.01188 -24.30546
   -0.23222  -0.35471   0.28144   0.02375 -24.30536
…
   -0.21508  -0.35043  -0.12440   2.31382 -24.28355
   -0.21336  -0.35851  -0.13256   2.32543 -24.28356
   -0.21165  -0.36658  -0.14072   2.33703 -24.28353
   bandindex:           2
   -0.21165  -0.36658   0.28144   0.00000 -24.30536
   -0.22193  -0.36065   0.28144   0.01188 -24.30546
   -0.23222  -0.35471   0.28144   0.02375 -24.30536
…

Columns 4 and 5 hold the data I want to plot.  Column 4 increases 
monotonically, then jumps back to 0 and starts increasing again.  These 
“logical blocks” are delimited by the “bandindex“ lines.

If I plot this as “p 'file' u 4:5 w p”, everything works fine.  But what 
I would like to do is plot it with lines; then I get diagonal lines 
through my plot whenever column 4 jumps.  How can I avoid these lines in 
a comfortable way?

Of course I can do “p "<perl -pe 's/band.*//' file" u 4:5 w l”, then the 
“logical blocks” become “gnuplot blocks” suppressing the diagonal lines. 
  But I do this a lot interactively so that would be a pain to type.  It 
is also not practical for me to change the format of the file.

One way that I could imagine this to work is if I could tell gnuplot 
that lines "*band*" should delimit blocks (or lines containing 
non-numeric data, say).

Another way would be if I could define an “input filter” to be applied 
to all data files.

Is anything like that possible in gnuplot?

This is mentioned in the INSTALL instructions, although it would be easy
to miss.   Basically you edit the file .../src/term.h and uncomment the
line containing     #include "regis.trm"

  /* REGIS graphics language */
  /* # include "regis.trm" */

[Gnuplot-info] Enable regis terminal when compile gnuplot?

[Xiaowei Z. <zh...@gm...>]

Hi all,

Is there a way I can enable "regis" terminal for the gnuplot 4.7 version?
The page instructing me how to build from source does not seem helpful.
I also do not know how to enable "regis" by reading "./configure
--help" outputs.
Any suggestion are welcomed.

Thanks,
Xiaowei

Re: [Gnuplot-info] x-axis label while using "every"

[Mahmood N. <nt_...@ya...>]

OK. Another way is to set xrange to the custom range and then plot all data points!

set xrange[1000:2000]
plot "data.txt" u 1

:)

Mahmood

If you know the exact labels you want and where you want them a
simpler method is 'set xtics'. From my finance demo script, this line
replaces the default x-axis labels with date labels.

set xtics ("6/03" 66, "7/03" 87, "8/03" 109, "9/03" 130, "10/03" 151,
"11/03" 174, "12/03" 193, "1/04" 215, "2/04" 235)

Yikes! Has it really been ten year since I wrote that?

[Mahmood N. <nt_...@ya...>]

It seems that this function works with #columns > 1. Am I right? 

The data file contains one column

40
50
20
10
....

So I have to use  

   plot "data.txt" u 1:xticlabels(stringcolumn(???)) every ::1000::2000

The stringcolumn() should take the row number. I wonder what is the argument then?
