I suggest you do not try to 'reinvent the wheel'.

Could you send commands to gnuplot using a pipe? That way. you can 
generate your plots using essentially a bunch of Fortran WRITE statements.

[Norwid B. <nb...@ya...>]

Romain,

if you want to address the computational part of the problem in
Fortran, and subsequently use gnuplot «just» to visualize the
difference plot between the recorded surface and the one fitted,
consider to address your question on the lively public discussion
board of fortran-lang.org, which is

[Gnuplot-info] fit 3d

[Romain G. <go...@in...>]

Hello, 

I'm a PhD student in modeling mechanical behavior of
materials. For my work, i need to fit a surface on a 3d curve and i do
it with gnuplot which is awesome. But now i need to do it by myself, i
need to create in Fortran, an algorithm which do the same thing as
gnuplot and i would like to know if it is possible to have a look at the
code doing the fit procedure in gnuplot, and how to do that ? 

Thank
you for your help. 

Best regards.

The basic limitation that hits "set multiplot" is that
gnuplot does not keep a history of session state;
it only stores the state of the current plot, i.e. the
result of the most recent 'plot' or 'splot' command.

This limitation can be bypassed for web-based (actually
browser-based) plot display applications, because you can
embed more than one plot in a single xml/html page without
using "set multiplot".  The gnuplot demo pages for
svg and canvas terminal are an example of this.

   http://gnuplot.sourceforge.net/demo_svg_5.5/
   http://gnuplot.sourceforge.net/demo_canvas_5.5/

In these cases the zooming is handled by a separate snippet of
javascript code for each plot including the current zoom state.
Gnuplot itself doesn't know anything about it obviously, since the
plots are displayed by a separate program.  The demo pages are
not laid out in a grid like typical multiplot output but
that's just a choice made by the script that creates them;
you could arrange the plots in a grid if you prefer.
The canvas terminal output support could be supplemented by
hot-key handling. The demo pages do not show an example of that.
I have not figured out how to present hot keys for svg output;
suggestions there would be welcome.

One more thought:

Although gnuplot does not keep a history of program state,
is does keep a history of commands.  You can reproduce a
full multiplot rather laboriously by stepping back through the
command history and re-executing the commands one-by-one that
originally created it.  A possible new program feature would
be to internally flag the first and last commands of a
multiplot sequence and allow the user to re-execute the
comple set in one go.  That would at least provide the
equivalent of a "remultiplot" command.
Unfortunately it wouldn't help with zooming.

Re: [Gnuplot-info] zooming interactively graphs in a multiplot

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

Dear Ruda,

yes, this is my current understanding.
Actually, the improved solution Friedrich proposed (https://stackoverflow.com/a/62170512/7295599) based on my initial workaround is (currently) the most convenient option I know of. As I understand, you want to zoom in/out interactively into indiviual sub-plots.
Maybe one could think of a very ugly and lengthy workaround, depending on the layout of your multiplot.
But in general, I don't see this option without changes in the gnuplot source code. For this you have to ask the developers of gnuplot.

best,
Theo.

thanks for your reply. So the answer is mostly that gnuplot is not

[Gnuplot-info] Data triming

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

Hello,

If I do
plot [0.1:] f(x)
I get scale from 0.1 to the maximum value of the plot
but values lower than 0.1 are possibly plotted.
Is there a way to really trim the values at 0.1?

Thanks

[Gnuplot-info] zooming interactively graphs in a multiplot

[Rudolf S. <rs...@di...>]

Hello,


I could not find an answer anywhere...

I use the x11 terminal with a multiplot to draw several graphs. Is it
possible to zoom in/out the individual graphs (with mouse 3rd button,
keypresses of u/a/n/p etc.) At this moment, when I try to zoom in one
graph, the zooming is performed but the graph suddenly occupies the
whole canvas and I cannot see the other graphs of the multiplot.


Thanks for comments!

The number of digits you get in that message is being controlled by a
hard-coded format string on line 1171 or line 1200 of fit.c in the
(commit a5562b) Gnuplot source code.  But one thing you could do is,
straight after the fit is completed, issue the command "print Offset",
which will provide a greater number of digits (controlled by a
different hard-coded format string, on line 1576 of util.c).

_However_: think carefully about whether printing any more digits is
useful, given that there will be some standard error in the inferred
value of the parameter.

I'd forgotten that; thanks.  On reflection, interpolating missing data is 
indeed the right thing to do (and to think that I gained a Distinction in

Perfect; that's exactly what I want!  Thanks; I'm not as familiar with

Not having seen an answer, I'll give it a shot. I believe that this is the
default for gnuplot and that having a missing datapoint entered with a '?'
should do what you want. I've not tried this, but I think that does the
trick.

Re: [Gnuplot-info] Gnuplot is interpolating between missing data

[Gabriel D. <gab...@gm...>]

Hello,

If you type "help missing" in an interactive gnuplot session, you'll see 
the following:

Gnuplot makes a distinction between missing data and
invalid data (e.g. "NaN", 1/0.).  For example invalid data causes a gap in a
line drawn through sequential data points; missing data does not.

So you should *not* set "x" as the string for missing data. Instead, try 
this:

$DATA << END
1 1
2 2
3 x
4 4
5 5
6 x
7 7
8 8
END

plot $DATA u 1:($2) w linespoints

You'll get a straight line with a two gaps.

I hope this helps.

Gabriel

[Gnuplot-info] Mouse behavior change 5.2.8 -> 5.4.2 with term = x11

[Glenn G. <gd...@zp...>]

Greetings gnuplotters,

Platform:           Arch linux, x86-64
Gnuplot versions:   gnuplot-5.2.8-2, gnuplot-5.4.2-1 (from Arch repo)

Minimal example:

   gnuplot> set term x11
   gnuplot> plot sin(x)
   gnuplot> unset mouse	

In 5.2.8, "unset mouse" entirely eliminates the mouse coordinate display
region at the bottom of the plot window, and the window then resizes
slightly (reduced height) to 'shrink wrap' the remaining plot area.

In 5.4.2, "unset mouse" only freezes the coordinate display, but the display
region itself remains visible within the plot window (showing the last set
of coordinates, frozen) and no resizing of the plot window occurs.

I went thru the various mouse options in 5.4.2 to see if perhaps there
might have been an option added since 5.2.8 that toggled this behavior,
but no joy.  Unable to find any combo that restores the old long-standing
behavior, but perhaps I missed it.

Can anyone reproduce this?  If so, is there some option or other trick
that I missed that will restore the old behavior? 

Thanks to all for maintaining gnuplot.

Re: [Gnuplot-info] Gnuplot is interpolating between missing data

[Norwid B. <nb...@ya...>]

Dave,

based on an entry on stack overflow[1], an input like the following
might fit your needs.  Save it as file ```test.dat```, then run
```gnuplot test.dat``` (in my case, it is gnuplot 5.4.1 which was
good enough, the plot includes the tick for x = 3 but discontinues
the line).

The MWE:
```
set style data lines
set terminal png
set output "see.png"
i=2
plot '-' using (column(i)):xticlabels(1) title columnheader(i)
A B
1 10
2 20
3 ?
4 40
5 50

Re: [Gnuplot-info] Attempting to install terminal wxt w/o success

[Alan C. <ala...@gm...>]

You didn't mention your operating system I don't think, you probably
shouldn't have to do all this manually.  With Debian/Raspbian/Ubuntu
you'd just type
  sudo apt-get update
  sudo apt-get install gnuplot

With OpenBSD which is about the messiest thing I've used, you'd do
something (as root) like
  cd /usr/ports/math/gnuplot
then make install.  After you'd built everything it needed.

But most packages require other packages.  Debian will (mostly)
install everything needed when you do the apt-get install gnuplot.
With OpenBSD I used to get a list from somewhere and install all the
needed stuff first, then gnuplot.  With OpenBSD I chose to compile
everything from source myself, with Linux I'm installing pre-compiled
binary packages which don't include anything extra.  Both methods work
but don't mix them.  In Linux if I wanted to  build gnuplot to use
wxwidgets I'd probably need a gnuplot-dev which includes the stuff
left out of the binary packages.  This is also a nuisance if you want
to build something outside the tree but build it using dependencies
you think you have installed.  A few months ago I built the latest
Firefox using mostly binaries that were installed but I had to add
several -dev packages because the install looks for headers and
libraries an average user doesn't have.

Re: [Gnuplot-info] Minor ticks missing for part of the subplot in a multiplot

[Vahid A. <vh2...@da...>]

The addition did not have any affect. I am still missing the minor ticks between 1 and 10.

Thanks,
Vahid

[Gnuplot-info] Attempting to install terminal wxt w/o success

[Eliezer R. <eli...@gm...>]

I watched 2 youtube videos in which the presenter used 'terminal wxt' to
plot various functions.  I downloaded and installed gnuplot 5.4.1.  I have
tried all the terminals that came with gnuplot, and none of them would 'plot
sin(x)'.  I am interested in plotting 2D graphs, and therefore I am
interested in 'terminal wxt'.  When I ran '/home/eliezer/gnuplot./configure'
I got the message

configure: WARNING: wxWidgets can't be found. You can try --with-wx=DIR to
give the right path to wx-config. The wxWidgets terminal will not be
compiled.

checking for CAIROPANGO... configure: WARNING:

Package requirements (cairo >= 0.9.0 pango >= 1.22 pangocairo >= 1.10) were
not met:

I downloaded wxWidgets-3.1.5 and extracted to
/home/Eliezer/gnuplot/wxWidgets-3.1.5/wxWidgets-3.1.5.  When I typed
'/home/Eliezer/gnuplot$ sudo install wxWidgets-3.1.5' the program asked for
a destination and I am hesitant to pick any destination; so I could use your
help here.  

 

I then downloaded and extracted 'cairo' to '~$ cairo' where ~ is
'/home/eliezer'.  I then got the message 'wxt terminal: no (requires C++,
wxWidgets>2.6, cairo>0.9, pango>1.22)' and 'cairo-based terminals: no
(requires cairo>=1.2, pango>=1.22, glib>=2.28)'

 

I then downloaded 'pango-1.48.5.tar.xz', but did nothing further because the
website indicated that its installation might be difficult.

 

I then downloaded 'glib-html-2.56.4.tar.gz and extracted it to
'home/Eliezer'.   I then issued the command 'install ~glib*
~/gnuplot/gnuplot-5.4.1' with the response 'install: omitting directory
'glib-html-2.56.4''.

 

I have attached the configlog file. In addition, the 'configure' command
generated the following output, which is not in the configure log,

Would you please look at the configlog output and tell me if any of the
missing files are necessary for my purposes, and help me with the software
necessary for the 'terminal wxt'

 

With  sincere appreciation,
