[Gnuplot-info] How & where to insert a script in order that gnuplot 3.7 can process it at a Kindle Fire 5 tablet?

[Bernabé E. <ben...@ya...>]

After trying in multiple ways of obtaining a recent version finally had to choose 3.7. Finding the corresponding user manual was even more dificult. 

After learning a few tricks decided to try to write a few scripts but the problem is "really" where & how to put them in order that gnuplot can find & execute them... 

Within gnuplot itself I can execute <!dir> and I got strucked by a screen much like a dos one??? I've ES File Explorer in the Kindle Fire gen #5 and can't find any of the files that that dir command shows; apparently they're within a restricted place to where I've no access. Without it, my question again is: how can I make & save a script in order that gnuplot find & execute them? 

Thanks in advanced for any help on this! 

PS. If anyone from here knows a more recent version that may work with this tablet let me know.

Re: [Gnuplot-info] histeps without the vertical lines

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

you could use xerrorbars...

However, the following code assumes that the x-values are equidistant
with steps of 1, so the +/- xerrorbar in the third column is fix (0.5)
I am sure there must be a better solution.

$Data <<EOD
1 2
2 4
3 5
4 3
5 1
EOD

set xrange [0:6]
set yrange [0:6]
set bars 0
plot $Data u 1:2:(0.5) ps 0 with xerrorbars

Hi! 

Can someone tell me how I can simultaneously multiply and divide $1 in gnuplot, like I have divided $1 previously using following script without rewrite data file.

tmargin did the trick, but the problem does not appear to match with your
analysis. I suspect an issue with x2tics.

First, putting a newline before the title did exactly nothing. Oh, well.
tmargin 5 had the expected effect, but left the very large gap between the
title and the x2tics labels. If I remove the labels, the gap between the
title and the graph shrinks significantly to what it should be and the
title is properly placed wit no adjustment needed.

If I add x2tics labels, the gap between the labels and the title increases
significantly and title moves up to the point that it no longer fits. the
size of the font does have an impact, but, in all cases the title moves up
to near (small font) the top of the image or past it (larger font). With
Cantarell Regular it hits the top at 16 points but is right at the top for
any size font.

To me (and Ihave not looked at the code) it looks like the problem is with
the space allowed for the x2tics labels. It appears that the space
allocated is at least twice the appropriate size that is used to calculate
the position of the title.

Thansk again for looking at this and I hope you can either track it down or
that someone else has and it will make it into either 5.0.6 or 5.1,
whichever comes first. I the meantime, tmargin is an acceptable work-around.

Thanks so much for looking at this and suggesting solutions!

I think that the problem is when the program allocates space for the
various titles, borders, tics, labels, etc, it does not take into account
that the title is going to be in a bigger font than the rest.  So it
leaves room for a 14pt title.  Then when it actual prints a 24pt title
there isn't enough room for the taller characters.

But even without the font change I agree that it leaves less room than
it ought to.   I've gone back and compared old gnuplot versions.
It looks to me that the problem crept in between versions 4.4 and version
4.6.  Version 4.4 placed the title with respect to the _top_ of the characters.
If you increased the font size the title extended further down, not up.
Version 4.6 changed this to some other logic, kept in version 5.0, and
the newer code doesn't deal well with the increase in font size.

Anyhow....
The placement of titles, axis labels, tics, etc has been reworked recently
in the development version.   Although this particular issue was not fixed
deliberately, the reworked code seems to handle it correctly.
So 5.1 is fine, but that doesn't help you with 5.0

Work-arounds:

- increase the top margin, e.g. set tmargin 6
  (you may have to experiment with the exact value)

- Place a newline in the title:
  set title "\nAnnual Rainfall" font ",24"

- Decrease the vertical size of the plot
  set size 1.0, 0.9

	hope that helps,

What is your exact version of gnuplot?

There has recently been a series of changes to the title and label placement
code in the development version.  I am not seeing a problem like this at the
moment, but possibly part way through the series of patches there was 
period when the page layout was incorrect.  

If you are running the development version, what does it report on entry as the
"last modified" date?

[Gnuplot-info] Titles cropped when x2tics labels are added

[Kevin O. <rko...@gm...>]

When I add labels above the plot (x2tics), my titles is cropped. There is a
great deal of space below the title.

Here is the setup:
set term gif font \"ariel,14\" size 1024, 600
set output "/usr/local/www/data/a_rain.gif"
set colors classic
set grid xtics ytics
set boxwidth 0.8 relative
set xlabel "Rainfall year is July 1 - June 30"
set ylabel "Inches"
set xrange [ 1996:2016 ]
set x2tics ($x2tics) font "ariel, 8"
set xtics ($xtics) font "ariel,8"
set title "Annual Rainfall" font "ariel,24"
plot "-" using 1:2 notitle with boxes fs solid lc rgb "black"

You can see the result at http://ykoberman.dlinkddns.com/a_rain.gif

I get similar results with other plots that include x2tic labels.

Any idea what is going on here?

Re: [Gnuplot-info] Default Terminal?

[DoctorT <Dr...@Ya...>]

Dear H-B B-2,

Thank you for your reply.

I know that the terminal can be re-set after installation.  But, when
GNUPLOT is first installed, what terminal, if any, is set as the default
terminal if I select default?

So that I can select the terminal, where can I find an explanation of the
features of the windows, wxt, and qt terminals?

Thank you!

Dr. T

PostScript (the language) does not support UTF-8.
There is nothing gnuplot can do about that.
Work-arounds are possible, but rather painful.  
If you want to pursue this, you could start by reading the file
     .../gnuplot/term/PostScript/unicode_maps.README

It would be much easier to switch to 
another terminal type that natively supports utf-8.
If your copy of gnuplot was not built with support for cairo or tikz,
perhaps you can take that up with whoever builtit?
Of the terminals you list as available, svg would be the best best.

[Gnuplot-info] Unicode characters

[Schmitzberger, F. <flo...@un...>]

Hi,

I want to print a per mil sign (‰) with Gnuplot (version 5.0.3). I am using postscript output terminal. I tried with 'set encoding utf8', and then call the per mil sign with the Unicode identifer {u+2030}. This does not seem to work.

I do not have pdfcairo available as an output terminal, which I understand would make printing Unicode characters easier.

How can I get Gnuplot to print a per mil sign?

No. The encoding is separate from the enhanced mark-up, if any.

Yes.

You need to make sure that the character strings to be printed
are in utf-8 encoding.   Normally that means the rest of the 
file is also in utf-8, but strictly speaking that isn't necessary.

That step would only be necessary if your file already contains
non-ascii characters that are in iso-8859-1 encoding.   For normal
text files this is not the case.   Is your linux environment not
already in utf-8?  That has been the linux default for a long time now.

That would work, so long as the program you are copying them from is
also running in a utf-8 environment.   I normally use kcharselect for
this (standard KDE utility) but I'm sure many other tools work as well.

A bit of Googling seems to indicate that nedit does not support utf-8.
How very antiquated.  If that is so, I seriously suggest that you should
switch to an editor that does, even at the cost of short-term pain as
you relearn a few tricks.

Nevertheless, if the byte-sequence you paste into it is correctly encoded
in utf-8 it will be properly handled by gnuplot even though your editor shows
only ?? instead of the desired symbol.  But this is obviously not ideal as
you will be working blind.

Not inside gnuplot.  But something equivalent to that is usually provided
by the operating environment itself.  It really depends on how your system
is configured.  For example if you have "Greek dead-key" mode enabled
for your keyboard input, then typing <greek><m><m> should get you
a greek character mu.

Also most editors (although apparently not Nedit) support something
of this sort. For example in the vim editor it is <ctrl-v>U03BC.

[Gnuplot-info] displaying unicode/utf-8 characters

[Kevin K. <kk...@gm...>]

It is not completely clear to me how to use utf-8 symbols in my plots.
Through web searching I have determined the following:



1. I need to use an enhanced output format

2. I need to set character encoding to utf-8

3. I need to ensure the gnuplot command file itself is in utf-8



Given the above, here are the commands I am using for 1. and 2.:



set term png size 1600x1200 enhanced

set encoding utf-8



Here is the linux command I use for part 3:



iconv -f iso-8859-1 -t utf-8 -o <utf-8_file> <original_file>



I want to use greek characters in my xlabels.  Every example I find online
says to simply copy the greek character from somewhere else and directly
paste it into my gnuplot command file.

The problem I have is that the text editor I am using (Nedit) does not seem
to support these symbols and they appear as '?' when I try to paste them
from somewhere else.  This then

produces a '?' character in my plot.



Is there a way to specify the character using its hex code?  For example,
the lowercase Greek 'mu' has code 0x3BC.  I tried using all of the
following to reference this character:



03BC

"03BC"

"U+03BC"

"\UO3BC"

"\u03BC"


But all of these strings end up being interpreted literally and do not
produce a 'mu' character.  Is there some specific syntax I can use to
display a unicode character using its hex code?

[Gnuplot-info] Compiling limited universal binaries for Linux and MacOSX

[Egon A. O. <e-...@no...>]

I am developing some open-source bioinformatics software that uses gnuplot to visualize sequence alignment results.  I'd like to be able to distribute gnuplot with my program without having to rely on the users having to install gnuplot themselves. My software calls on gnuplot to produce plots using the pngcairo terminal.  I know that OS X doesn't like static linking of binaries (http://stackoverflow.com/questions/5259249/creating-static-mac-os-x-c-build) but I think the only library that I'd really need to static link would be the cairo libraries. Does anyone have any suggestions or ideas as to how I might be able to manage producing "universal-ish" binaries of gnuplot for OS X and Linux platforms with only a very limited set of statically-linked terminal options? If I have to find another option, I will, but I thought I'd ask first.

Thanks,
- Egon

Hi Tatsuro
Here are a range of options outside of gnuplot in a linux/unix/BSD shell that should work:
http://stackoverflow.com/questions/742466/how-can-i-reverse-the-order-of-lines-in-a-file

you can call a shell command from within gnuplot to do that if necessary. Read the manual for how to do that.

Keep in mind that gnuplot is a plotting software and is not indented for data processing.

There is limitation of data processing facility of gnuplot.

In your case, as some people wrote, sort command is useful tool.

[Gnuplot-info] Could you please help me on how to use 'set key' of my figure?

[Wenqiang L. <liu...@16...>]

Dear everyone,
My current setting is 'set key box lw 0.5 reverse Left width 1', 
however, the space between the sample point&words and the box border is 
still too large for me. I have tried to use some smaller number like 
'set key box lw 0.5 reverse Left width 0.001' in my script, but the 
width seems will not change anymore. I could not change the space 
between the key and the box borders. Could you please tell me how to do 
that?
Another question is that, in x11 terminal, I can use 'test' to see the 
results of linetype, linewidth and so on. If I set terminal to 
postscript, typing 'test' gives lots of words which is not so easy to 
understand. How can I output the illustration of the test results.
Any help would be much appreciated!

Best Regards
Liu

That would depend on what you mean by "throughout".

Thank y'all for your responses. Let me clear my question. Lets say I have
this file:
   
-0.00512366  0.0156186  
-0.00510697  0.0154651  
-0.00509028  0.015312

-0.0050569  0.0150072  
-0.00504021  0.0148556

And I want to move my last row to the top of my data file and so on. so I
could have :

-0.00504021  0.0148556
-0.0050569  0.0150072
-0.00507359  0.0151593
-0.00509028  0.015312
-0.00510697  0.0154651
-0.00512366  0.0156186

I know that I could use "set xrange [* : *] reverse" command to do that when
I am plotting it but I want to save the change in my data file.

Thank you
*******************************************************************************

set xrange [* : *] reverse
set table 'data.txt'
plot (datafilename)
unset table

But this add 'i' to the third column.

See the output the below command or gnuplot manual [1]
gnuplot> help table

Re: [Gnuplot-info] Sorting

[Cédric O. <ced...@un...>]

Hello,

The following link

http://folk.uio.no/hpl/scripting/doc/gnuplot/Kawano/datafile3-e.html

shows how to use unix commands like sort within gnuplot.

For your example, you can also use the 'tac' command instead of 'sort'. 
'tac' reverses the content of a file (cat <-> tac).
