Subject: Gnuplot is interpolating between missing data

Gnuplot (on a Mac), 5.4p2

I have some missing data which I indicate with "x" (set datafile missing "x"), 
yet Gnuplot seems to be drawing a straight line between the valid data. 
Shouldn't it be blank instead?

-- Dave

Hello,

As a result of the fit, I get:
Offset          = -2.48586e+07

How can I display more digits?

Thanks

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.

I made a question on stackexchange here:

https://stackoverflow.com/questions/69057491/gnuplot-erases-circles-when-zoomed-in

illustrating a problem I'm having with plotting circles on a dataset 
when zooming in. Any help would be appreciated.

Thanks,

Patrick

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
e
```

Dear gnuplot users&develepers,

Would you pls help? Many thanks.

I resolved the issue by first plotting an empty plot with the proper minor ticks. Then I added my plot on top of the empty plot. Not ideal but it works.

Best,
Vahid

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.

Education is contagious.

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

before the bottom left plot try to add the line

set ytics add ('' 10)

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

Dear Gnuplot Community,

The following script combines 4 subplots into one single plot with no spacing between subplots. The y-axis is log scale.

set term pdf size 4,3 enhanced font 'Times New Roman,16’

# Physical constants and conversion factors
PI = 3.14159
h_bar = 6.582119e-16
c = 2.9987e8
rad_ps_to_meV = 1E12*h_bar*1000
inv_cm_to_meV = 100*2*PI*c*h_bar*1000

set output "./scatter-rate/comparison.pdf"

MMIDY = (MBOT + MTOP) / 2
MMIDX = (MLEFT + MRIGHT) / 2

#top right subplot
set format y ‘ '
set lmargin at screen MMIDX
set rmargin at screen MRIGHT

#bottom left subplot

set format y '10^{%T}'
set format x '%g'
set xtics 0,20,80
set lmargin at screen MLEFT
set rmargin at screen MMIDX
set tmargin at screen MMIDY
set bmargin at screen MBOT
plot "./data/1.10/collected-data.dat" u ($4*rad_ps_to_meV):9 w p ps PS pt 7 lc ‘black’

#bottom right subplot
set xtics 20
set format y ‘ '
set rmargin at screen MRIGHT
set lmargin at screen MMIDX
plot "./data/graphene/collected-data.dat" u ($4*rad_ps_to_meV):9 w p ps PS pt 7 lc ‘black'


Here, the y-axis major tick label 10^1 from the bottom left subplot overlaps with the 10^-3 label from the top left subplot.

I would like to avoid printing the 10^1 label on the y-axis of the bottom left subplot. So I used the following for the bottom left y-axis:

set yrange [1e-3:10]
set ytics 1e-3, 1e-1, 1
set mytics 10

However now I am missing the 10 minor ticks between 1 and 10 in the bottom subplots. Below 1, all minor ticks are there. Is there a way to preserve the minor ticks between 1 and 10 in the above example?

Thank you,
Vahid

Is there any reason the native SVG terminal type does not work for you?  It
creates interactive plots.

 by a factor of <w>.

 <font> is the name of the default font to use (default Arial) and
 <fontsize> is the font size (in points, default 12). SVG viewing
 programs may substitute other fonts when the file is displayed.

 The enhanced text mode syntax is shared with other gnuplot terminal types.
 See `enhanced` for more details.

 The `mouse` option tells gnuplot to add support for mouse tracking and for
 toggling individual plots on/off by clicking on the corresponding key
entry.
 By default this is done by including a link that points to a script in a
 local directory, usually /usr/local/share/gnuplot/<version>/js.
 You can change this by using the `jsdir` option to specify either a
 different local directory or a general URL. The latter is usually
 appropriate if you are embedding the svg into a web page.
 Alternatively, the `standalone` option embeds the mousing code in the svg
 document itself rather than linking to an external resource.

 When an SVG file will be used in conjunction with external files,
 e.g. if it is referenced by javascript code in a web page or parent
document,
 then a unique name is required to avoid potential conflicting references
 to other SVG plots.  Use the `name` option to ensure uniqueness.

We have a bash script that uses gnuplot via its CLI to output simple histograms in GIF format.  We would like to change that output in SVG or HTML5 format, so there is mouse interactivity.  We're hoping to just hire someone to knock this out for us!  But if no one is interested, any guidance would be appreciated.


Here's an example of the code:



 /usr/local/bin/gnuplot << EOF
 # set terminal size and background color and medium font size
 set terminal gif medium size $width,$height background rgb "$bgcolor"
 unset key
 unset tics
 unset border
 set bmargin 0
 set lmargin 0
 set rmargin 0
 set tmargin 0
 set output "${outdir}/${inname}_histogram_${colormode}.gif"
 set xrange [0:255]
 set yrange [0:$ymax]
 plot "tmpT.txt" using 1:2 with filledcurves below x1 linecolor "$linecolor"
 # EOF must not have any white space before it or does not work
EOF

Can gnuplot do this?  I didn't find anything relevant searching.  The system I built 5.4.1 on is currently inaccessible so I can't review the demos.

As an example use case:

Plot ground topography in 3D with an overlay of rainfall or snowpack to show the relationship between topography, wind direction and precipitation.

There are a lot of geoscience applications for such a graphics presentation.

Thanks,
Reg

That would be because the entire concept of "continuity" is effectively 
meaningless for discrete data.

Let's recall the definition of the term "continuity": for any epsilon > 
0 there is a delta > 0 such that for all x with ||x - x0|| < delta, 
||f(x) - f(x0)|| < epsilon with x and x0 in the definition set of `f. 
In simpler words: no jumps in the interior (maximal open subset) of the 
definition set of f.

On discrete data sets you can always select delta smaller than the 
smallest distance of any two points in the data set, and thus force x=x0 
as the only choice.  I.e. since the definition set consists of isolated 
positions only, there is no interior for the definition to attach to.

Discrete data are thus, by definition, _always_ continuous.  That 
renders the concept tautological on them, and robs it of any meaning.

Hi,

I'd like produce a surface plot with splot of a function F(x,y) that is 
only given as a discrete data set read from a file. One of the corners 
of the function's  (x,y) support is (0,0) and I know the function is 
discontinuous at F(0,0) depending on how one approaches (0,0), with a 
discontinuous jump for F(x,0) for x going to 0. Is there a specific way 
to treat the (0,0) input point in splot to reflect the discontinuity?

I've googled around, but all the info I could find on how to plot 
discontinuities seem to assume that the function F(x,y) is explicitly given.

Thank you.

Correction:
Please ignore that particular suggestion.
It is relevant to installing support libraries, but not
to installing the program itself.

If you need to add "/usr/local/bin" to your path permanently
it goes in your personal profile file (probably $HOME/.bashrc)
or somewhere in the /etc/profile.d/* system templates.

If you want to manually remove files installed by apt/dpkg look in
/var/lib/dpkg/info/gnuplot*.list

Except if Ubuntu uses Debian's alternatives system of symlinks gnuplot
is tangled up in that.  galternatives is the GUI tool for dealing with
it, or update-alternatives for command line.

And the binary here at least (Raspbian) is /usr/bin/gnuplot-qt and the
list is in gnuplot-qt.list

That configures it in such a way that the final "install" command
will put it in $HOME/gnuplot/gnuplot-5.4.1/bin.

That would make sense if you were building it on someone else's
machine where you did not have permission to change anything outside
of your own login directory.
It doesn't make much sense on your own machine - if it's in your
own directory you can run it even without the "install" step.

Do you mean "export PATH=$HOME/gnuplot/gnuplot-5.4.1/bin:$PATH"?
That should work, at least for the terminal session you are in at that moment.

To make it permanent you would have to add that directory to /etc/ld.so.conf.d
But that would be crazy.  If you have root permission to modify the
system load path then you would be better off using that permission 
to install the program in the normal place - /usr/bin  (or /usr/local/bin)

> I checked and the addition was included in the PATH.  I tested gnuplot again and got gnuplo-5.0.3.

I looked at these files with the editor to find that they each had a long list of alphanumeric characters.  I tried to remove them with a response that "permission denied".

That is the purpose of using the "sudo" command wrapper.
It lets you add/remove/modify files that require system privilege.

If your system doesn't normally use the /usr/local directories
(I don't know about Ubuntu), then you can either 

(a)
add /usr/local to  /etc/ld.so.conf.d
(b)
make /usr/local be a symlink to /usr       before doing "make install" !!
(c)
modify the configure at step #1 to be
./configure --prefix=/usr

There might still be some error messages from "make install"
if your system uses a different convention than the gnuplot 
configure script expects for certain things.
For example it might well be that Ubuntu keeps TeX support files
in a different place than gnuplot's default.

Yeah, don't mix building from source with using debs.  Do a dpkg purge
gnuplot, then make uninstall it.  Unless you really need the latest version
apt-get install gnuplot should work.  But the debs can be a year or more
old by the time they trickle through the stages of testing so it's almost
always a different version.

You are mixing up two very different things.
#1 is building and installing gnuplot from source files.
#2 is downloading and installing whatever gnuplot
package your distribution provides.

Pick one or the other.

Good so far.  Assuming that you were happy with the 
output it shows about what optional components are
being built, you should now have a runnable gnuplot
sitting in the directory where you built it.

>                sudo apt install gnuplot 

But now you go completely wrong.
"apt install" ignores the thing you just built.
It goes out and looks for a package named "gnuplot" on
some Ubuntu web site somewhere.  Then installs it.
Not the one you built.

>                make check

That is checking the copy you built at step 1.

>                make install

That is trying to insall the copy you just checked,
but it will probably fail because you don't have the
right permissions.  Probably you need

                sudo make install

Now you are back in camp #2. It is reporting on installation
of the Ubuntu package rather than the newer gnuplot you just built.
Don't do this.   Do _not_ run "apt".

	hope that helps,

I am trying to install gnuplot-5.4.1 in Linux OS using Ubuntu 64 bit 16.04.3

 

I want to use gnuplot to plot the bandstructure of Pd using the ABINIT code.

 

I have tried to install gnuplot-5.4.1 without success.  I have read the faq
"How do I compile gnuplot on my system" and the INSTALL file in the
gnuplot-5.4.1 folder.  

 

I downloaded gnuplot-5.4.1.tar.gz and unzipped the file into
$HOME/gnuplot/gunuplot-5.4.1.

 

I then entered the commands

               ./configure

               make

               sudo apt install gnuplot 

               make check

               make install

The 'sudo' command ran returning

               Reading package lists... Done

Building dependency tree       

Reading state information... Done

gnuplot is already the newest version (4.6.6-3ubuntu0.1).

The following packages were automatically installed and are no longer
required:

               libdumbnet1 libgtkmm-2.4-1v5 libllvm5.0 libmspack0 libxmlsec1

               libxmlsec1-openssl snapd-login-service

The make install command ran and returned at the end 

/bin/mkdir -p '/usr/local/share/gnuplot/5.4/js'

/bin/mkdir: cannot create directory '/usr/local/share/gnuplot': Permission
denied

Makefile:374: recipe for target 'install-jsDATA' failed

The 'make check' command  ran returning for most of it 'WARNING: plotting
with an 'unknown' terminal.  No output will be generated.  Please select a
terminal with 'set terminal'. '  At the end of the output the command
returned

About 5 years ago, I installed gnuplot-5.0.3, and every time I give the
command 'gnuplot', gnuplot-5.0.3 opens.  I listened to 2 youtube tutorials
given  with gnuplot-5.5 and terminal 'wxt'.  Gnuplot-5.0.3 does not have
this terminal.  Does gnuplot-5.4.1?

 

I hope you can resolve my problem.
