Not python, unfortunately. But perhaps python has similar constructs to
the ones shown here:

[Gnuplot-info] gnuplot window to front (Python)

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

With a Python PyQt5 GUI (Win7/64), I am generating gnuplot code which I send to gnuplot.
The Python code is basically something like:
...
process = QProcess()
process.start(r"C:\Programs\gnuplot\bin\gnuplot.exe", ["-p"])
# e.g. if some button pushed...
process.write(b"plot sin(x)\n")
response = process.readAllStandardOutput()
...
Which works ok.
However, the gnuplot window always stays behind the PyQt5 window.
How to bring the gnuplot window to the front?
Something like "set term wxt raise" (of course ;-) doesn't help.
Actually, it might be more a Python question rather than a gnuplot question.
But maybe gnuplot users which are also programming in Python could give me some hints?

[Gnuplot-info] sin(x)/x smoothing option?

[Reginald B. <pul...@ya...>]

Is there an option to apply a sin(x)/x aka Whittaker interpolator to the points when plotting?  I'm working on a digital signal processing tutorial and it would be helpful to be able to apply a sinc interpolator to the data points.

If there is not, I'd like to suggest considering that as an enhancement as it is widely used in DSP applications.

Please see the documentation for "plot with table"
Here is the first paragraph but you should read the entire section:

%%%%%
 This discussion applies only to the special plot style `with table`.

 To avoid any style-dependent processing of the input data being tabulated
 (smoothing, errorbar expansion, secondary range checking, etc), or to increase
 the number of columns that can be tabulated, use the keyword "table" instead of
 a normal plot style.  In this case the output does not contain an extra, last,
 column of flags `i`, `o`, `u` indicated inrange/outrange/undefined.
 The destination for output must first be specified with `set table <where>`.
 For example

      set table $DATABLOCK1
      plot <file> using 1:2:3:4:($5+$6):(func($7)):8:9:10 with table
%%%%%

Re: [Gnuplot-info] set table

[ivana r. <iva...@mf...>]

Hi Patrick,

in the data file you've sent me there a comma works as a separator, so your
data separator is set probably to ',' or ', '. Contrary to 'whitespace'
separator, it does depend on the number of spaces in the second case and,
moreover, table-print always put some extra spaces.

So what to do....

Solution 1:
Different format for both data-sources, as you've suggested:

> set datafile separator ","
> set table $DATA
> plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3
> unset table
> plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3, $DATA u 1:2 " %lf
%lf"

Solution 2:
Put both separators to comma:
> set datafile separator ","
> set table $DATA separator ","
> plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3 with table
> # with table has not to be omitted
> unset table
> plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3, $DATA u 1:2

Solution 3:
Put both separators to whitespace:
> set datafile separator whitespace
> set table $DATA
> plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3
> unset table
> plot "<tr , ' ' <070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3, $DATA u
1:2

Sincerely

I.

[Gnuplot-info] 3 variables in table

[Patrick D. <pd...@gm...>]

Hello,

I tried

set table $DATA; plot "070618_C2H2_R2_0_2ubar_11.txt" u ($1/1000):($3):($4) "%lf,%lf,%lf,%lf" ; unset table


But it seems that I cannot have 3 variable in the table
Am I correct ? Are there other options?

Thank.

Re: [Gnuplot-info] set table

[ivana r. <iva...@mf...>]

Hi Patrick,

you can set table separator directly after table (see 'help table') but the
troubles are probably elsewhere.

I still cannot reproduce the behaviour you get.
What is yours OS?
Do you have the same troubles with completely new testing file or with
datablock plotted from a function or set directly in gnuplot?
Do you have the same troubles, if you save table to external file instead
of gnuplot datablock?
Did you check the original data-file for special chars (e.g., 'cat -A')?
If nothing helps, could you send me the trouble-making file?

Regards

I.

Re: [Gnuplot-info] set table

[Patrick D. <pd...@gm...>]

Hello Eva,

Same thing with ($1/1000):($3+0)

But:
plot $DATA u 1:2                                    
         warning: Skipping data file with no valid points
                         ^
         x range is invalid
plot $DATA u 0:1 plots the same as plot $DATA

But 
set datafile separator " "
gives 
plot $DATA       
         warning: Skipping data file with no valid points
                   ^
         x range is invalid

I guess that it is an issue with the formatting

Re: [Gnuplot-info] set table

[ivana r. <iva...@mf...>]

Hi Patrick,

even if you force two columns, e.g. 'plot $DATA u 1:2'?

It seems to me that gnuplot take the table $DATA as it has only one
numerical column. Is it possible that there are some special chars left?

If so, it should help to get table via 'plot file using
($1/1000):($3+0)' instead as well.

I.

Re: [Gnuplot-info] set table

[Patrick D. <pd...@gm...>]

Hello Iva,

Thank for the feedback,

print $DATA
# x y type
 4.41863e+07 -0.037085  i
 4.42347e+07 -0.039582  i
 4.42836e+07 -0.0414126  i
 4.43342e+07 -0.0432468  i

seems OK, but
plot $DATA
the first column versus an index.
0  4.41863e+07
1 4.42347e+07
2 4.42836e+07
3 4.43342e+07

Re: [Gnuplot-info] set table

[ivana r. <iva...@mf...>]

Hi Patrick,

> It does not work

what do you mean, what happens, is there any error message?

Anyhow, as the construction works in same cases, e.g. with a function
to be plotted, there is probably some garbage in your data. Then
'using 1:2' should help as well.

You can also check the $TABLE easily via:
print $TABLE

[Gnuplot-info] set table

[Patrick D. <pd...@gm...>]

Hello,

if I do 
plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3

Every thing is OK

If I do

set table $DATA           
plot "070618_C2H2_R2_2ubar_1.txt" using ($1/1000):3
unset table                                        
plot $DATA  

It does not work

Why?

Thank for your help.

Re: [Gnuplot-info] help converting old gnuplot input to gnuplot 4.6

[Gunter K. <gu...@pe...>]

About Gnuplot < 4.6 I don't know much. But for getting the line styles
work in >=5.0 I had to do the following:

if(GPVAL_VERSION >= 5.0){set for [i=1:8] linetype i dashtype i; set
format '%h'}


Kind regards,

I think I will need to investigate more. From what I can tell is that it
uses lifestyles, but these are set somewhere else. And it seems there
may be a post process tool that changes the linestyles in eps files as well.

[Gnuplot-info] help converting old gnuplot input to gnuplot 4.6

[Jelle de J. <jel...@po...>]

Hello everybody,

I am patching up some older tool that uses gnuplot to generate documents
and I could use some help, with the gnuplot input syntax reference.

/usr/bin/gnuplot --version
gnuplot 4.6 patchlevel 2

This is my old gnuplot input file: https://paste.debian.net/hidden/4e7b108e/

In the new output some of the lines are the wrong colour. What are the
commands responsible for the lines? So I can check and reference the old
and new syntax and change the input file?

Thank you.

Kind regards and best wishes,

I think that this mailing list is not suitable to discuss what you wrote.
Please post your issues to the bug ticket on gnuplot sourceforge site.

Bastian has been working extensively for gnuplot on native windows.
I think that you should raise his attention on this matter.

I had that issue about 14 years ago and put in a signal handler that killed
gnuplot on a SIGTERM or other terminating signals. (I was forking gnuplot
off of a parent that used chat to communicate with gnuplot.) That is
another approach that worked well before pause came on the scene.

Re: [Gnuplot-info] Auto-Closing gnuplot on closing the gnuplot window

[Gunter K. <gu...@pe...>]

I hate finding threads in the internet that don't contain a solution =>
writing how far I got:

 - Windows allows to open applications with and without a console.
Opening gnuplot (or wgnuplot) causes 100% of one CPU to be consumed.
 - Windows allows to hide the console. If the console of gnuplot or
wgnuplot is hidden the plot window is hidden, too.

=> I can open gnuplot with a console and show the console and will get a
plot - and a superfluous window. But I guess I can live with that.

And I have to add a 3-line construct to my file in order to make the
console window autoclose whilst keeping the window live (aka reacting to
the mouse):


    bind "Close" "exit gnuplot"
    pause mouse close
    exit

Kind regards,

 Gunter.

It did. Thanks a lot!

...and I have found out that if you open gnuplot as a console app it
doesn't need 100% of one CPU - even if it still refuses to open a plot
window in that case. No idea why. But - I don't even own an own windows
installation...

Kind regards,

Encountered another proble, this time on Ms Windows: the file I've sent with my first mail if gnuplot is started from the console opens a plot window.
If started from wxMaxima, though, gnuplot 5.2 pl 4 uses 100% of one CPU and never opens the plot window.

What might have gone wrong?

Kind regards,

   Gunter.

I think you are running into idiosyncracies of the particular 
desktop manager or environment.  The issue is due partly to what
signal is sent when the plot window is closed, and which process that
signal is delivered to.  There may also be a difference depending on
which interactive gnuplot terminal is being used.

For my desktop (KDE 5) and the qt terminal, I get the behavior you
want if I close the plot window with "q" or "cntrl-q" but not if I
close it with "alt-F4" or the window border decoration "x".
Both qt and x11 work as desired if I add the command

    bind "Close" "exit gnuplot"

before the pause command.

That was exactly what I was searching for.

On my gnuplot 5.2 patchlevel 2 it only nearly does what I want, though:

It waits until I first close the window and then press <enter> in the
terminal I opened gnuplot from. If I first press <enter> in the terminal
and then close the gnuplot window or fail to press <enter> gnuplot won't
close.

I'll attach a simple testfile to this mail.

   gnuplot wait.gnuplot

doesn't work as expected but

   echo |gnuplot wait.gnuplot

does.

If I did the Right Thing perhaps I can mimic the latter command somehow...

Kind regards,

   Gunter.

That's from 10 years ago, but the answer is correct.
Instead of "pause -1" you want some variant of "pause mouse",
possibly "pause mouse close"
.
See the documentation for the pause command or "help pause".

[Gnuplot-info] Auto-Closing gnuplot on closing the gnuplot window

[Gunter K. <gu...@pe...>]

Dear all,

wxMaxima allows to automatically embed gnuplot plots into a maths
worksheet: The plot is generated with the png (or pngcairo) terminal and
the bitmap is embedded. Tomorrow's nightly build also on right-clicking
a plot allows to start a separate gnuplot process - which popups a
window in which the user can interactively turn a 3d plot, zoom in and
out or measure coordinates with the cursor. There is a problem left, though:

- If I start gnuplot as "gnuplot -p /tmp/maxoutXXX.gnuplot" gnuplot
closes when the user closes gnuplot's plot window. But the displayed
graphics is is not interactive (for example a 3d image cannot be turned
using the mouse)
 - and if /tmp/maxoutXXX.gnuplot ends with a "pause -1" the image can be
turned with the mouse. But in this case gnuplot doesn't close when the
user dismisses the interactive gnuplot window, which makes gnuplot act
like a big memory leak.

In the internet I find many related questions like
https://groups.google.com/forum/#!topic/comp.graphics.apps.gnuplot/bE0RHH_l7aI

...but until now I didn't find a real solution to my question (most of
the questions were from the gnuplot 4.0 times, though) so I'm asking here.

Thanks in advance,
and kind regards,

    Gunter.
