To me this seems too specialized a use to be worth hard-coding it.

How about using one of the general mechanisms that already exist?

For example:

  PS = 0
  plot "foo" with linespoints pointsize PS

# Now you have a plot on the screen that shows no visible points

  bind "1" "PS=1; replot"
  bind "2" "PS=2; replot"
  bind "0" "PS=0; replot"

# Now you have defined hot-keys to change the size of the points in
# the existing plot.

Or a similar example that uses a hotkey to toggle one plot of many:

  PS1=PS2=PS3=PS4=0
  bind "1" "PS1 = PS1 ? 0 : 1; replot"
  bind "2" "PS2 = PS2 ? 0 : 1; replot"
  bind "3" "PS3 = PS3 ? 0 : 1; replot"
  bind "4" "PS4 = PS4 ? 0 : 1; replot"

  plot FILE1 with lp ps PS1, FILE2 with lp ps PS2, FILE3 with lp ps PS3

Re: Click curve to highlight?

[Brandon T. <bam...@gm...>]

Temporarily changing a data set from 'line' to 'linespoints' allows
you to quickly see where and/or how many points exist, without having
to change a script or do a 'replot'.  Or if you have several lines on
top of each other you could quickly 'highlight' one by changing it to
linespoints.  It's just handy at times.

The suggestion to click the in the key to make the line invisible, the
invert it, would work I guess, or...

Currently you can click on a line's entry in the key to make it
'invisible', at least for some terminals.  How about an option to let
that same click change the line to 'linespoints' instead of making it
invisible?

all lines are different colours by default, so what is the need. Are 
talking about a monochrome config. Please explain the need.

several terminals : eg wxt , qt and svg  will hide the line if you click 
on its legend in the key. That can help distinguish it, or alternatively 
can be used to hide other lines to have a less cluttered view.

You can't change the plot style, but you can make the selected
plot be the only thing showing:

1) Click on plot's title in the key area
   (this will blank out that plot, leaving others visible)
2) Use hotkey 'i' to invert which plots are visible/invisible
   Now your selected plot is the only one showing

Click curve to highlight?

[Brandon T. <bam...@gm...>]

Is there any way to 'highlight' a curve by clicking on it?

For example, if I have data plotted as a line, if I could just
mouse-click anywhere on that line and have it change to linespoints
until I click somewhere off of the line?  This would allow me to
temporarily see where the individual data points are without having to
redraw using linespoints.  Make sense?  I've seen this with other
plotting tools and it is very helpful.

Short list of configuration issues for Linux Mint

[Daniel J S. <dan...@ie...>]

I've upgraded to Linux Mint and noticed a few small issues with 
configuration and linking.

TERMLIBS DEFINITION FOR wxWidgets COMPILATION
---------------------------------------------
I came across this linking error:

/usr/bin/ld: wxterminal/wxt_gui.o: undefined reference to symbol 
'XInitThreads'
//usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO 
missing from command line
collect2: error: ld returned 1 exit status

which luckily I found details about in the list archive around 2014. 
Per one of Ethan's posts:

-----
Could you please try

TERMLIBS="-lX11" ./configure
-----

That fixed the linking problem.  I'm just curious what the status of 
this issue is.  Ethan wrote something about the issue should be fixed in 
wxWidgets.  Has this been addressed in that project?  Is it simply that 
Ubuntu/Mint lags a bit in up-to-date software utilities?  (The 
repository does seem to be behind a bit, at least in the non-major 
programs.)


CONFIGURATION DOESN'T CHECK FOR Qt PROGRAM lrelease
---------------------------------------------------
I then ran into:

	mv -f $depbase.Tpo $depbase.Po

sebald@ ~ $ ls /usr/lib/x86_64-linux-gnu/qt5/bin
moc  qdbuscpp2xml  qdbusxml2cpp  qdoc  qmake  rcc  syncqt.pl  uic

so I had to add package qttools5-dev-tools.  Is this another package in 
the list of Qt libraries (i.e., Qt5Core, Qt5Gui, Qt5Svg, etc.) to check 
for?  Or is more a helper routine that is expected to be present? 
(There are a lot of instances in config where a minor program can be 
missing and isn't checked supplied.)


IS IT REALLY A WARNING TO HAVE Qt5?
-----------------------------------
After supplying all the needed Qt5 libraries (through a bit of 
straightforward trial and error), the source code compiles and links and 
runs the 'qt' terminal just fine.  Yet, in the configuration log is the 
following warning:

checking for CAIROPDF... yes
checking for CAIROEPS... yes
checking for QT... yes
configure: WARNING: The Qt terminal will use Qt5.
checking for vfork.h... (cached) no

Why is this a warning?  If there is something wrong with Qt5, perhaps 
the warning could state what it is.  If there is no problem with Qt5, 
then remove the "WARNING" portion and just state The Qt terminal will 
use Qt5.  Actually the whole message could be left out because near the 
end of the log is a summary which states:

   wxt terminal: yes
   Qt terminal: yes (qt5)


LIBWX, MORE THAN JUST BASE
--------------------------
I ran into this warning:

configure: WARNING: You only have the 'base' flavor of wxWidgets. A full 
wxWidgets library is required. On Debian/Ubuntu, please make sure that 
you have a 'libwx...-dev' package other than just 'libwxbase...-dev' 
installed. The wxWidgets terminal will not be compiled.

Linux Mint is based on Ubuntu.  I couldn't find 'libwx...-dev'.  I think 
the one that made the library complete and eliminated the warning for me 
was 'libwxgtk3.0-dev'.

And...is it possible to overlap over each cell the actual value ?
There is an example on the doc, but when I modify my gp to follow it, I get

The "pixels" keyword did it ! Awesome :-)

The smoothing is probably happening in the program that you use to
view the pdf file.

Try adding the keyword "pixels":

     plot ... with image pixels

That will change the gnuplot output such that the viewer program
will probably not recognize it as something that can be smoothed.  
See for example the 5th plot in this set of examples

     http://gnuplot.sourceforge.net/demo_svg_5.1/heatmaps.html

Re: heat map ?

[Valerio S. <val...@gm...>]

Help everyone,
following Ethan advice, i've tried to simply the .gp file. Now it looks
like this:

set term pdfcairo
set output "macrobench_latency_heat.pdf"
load "../styles.inc"
set size 0.9,1.0
set lmargin 20
set rmargin 20
set palette defined (0.0 "white", 1.0 "blue")
set tic scale 0
set cblabel "Latency (ms)"
set datafile separator comma
plot\
 "heatmap_latencies_handmade.txt" matrix rowheaders columnheaders u 1:2:3
with image notable

Now, how do I show you the result ? I've uploaded it here
http://postimg.org/image/sssos6q9j/full/
but here, it shows it something that is completely different from the PDF
that I see, in which the cells are smoothed/interpolated...for some reason..

Ideas?

You are trying to do something like the blue-tinted images Valerio? 
What I see from your example is a greyscale which is sort of the right 
idea, and I think you should be able to achieve most of the other 
properties in those blue-tinted images.  You can

1) Change the color map (palette) from greyscale to one that has the 
blue tint.  (And perhaps there is already a predefined color map that is 
close.)

http://gnuplot.sourceforge.net/demo_5.0/heatmaps.html

2) Apply a non-90 degree rotation to the x-axis annotation.

http://gnuplot.sourceforge.net/demo_5.0/tics.html

3) Draw individual white lines across the axes to create the borders 
between individual elements.

http://gnuplot.sourceforge.net/demo_5.0/rgb_variable.html

Look through some of the demos here for ideas:

http://gnuplot.sourceforge.net/demo_5.0/
http://gnuplot.sourceforge.net/demo_5.1/

Most of those commands are irrelevant to what you want.
This is not a 3D surface, so you don't need "splot".
The colors are categorical, not smoothed, so you don't want pm3d.
Disregarding labels, it is sufficient to say

  set datafile separator comma
  set palette defined (0.0 "white", 1.0 "blue")
  plot "heatmap_latencies.txt" matrix rowheaders columnheaders with image

heat map ?

[Valerio S. <val...@gm...>]

Hello,
i've been trying to make an heat map that looks like the one in this blog
entry
https://learnr.wordpress.com/2010/01/26/ggplot2-quick-heatmap-plotting/
Unfortunately they don't use gnuplot.

My attempt so far produces a poor result, i think because I'm not using the
right approach.

Here's my current version:

set term pdfcairo
set output "latency_heat.pdf"
load "../styles.inc"
set size 0.9,1.0
set lmargin 15
set rmargin 20
set pm3d #interpolate 0,100
set view map scale 1
set style func pm3d
set style data pm3d;
set dgrid3d
set pal defined ( 0 0 0 0, 1 1 1 1 )
set tic scale 0
set cblabel "Latency (ms)"
set datafile separator comma
splot "heatmap_latencies.txt" matrix rowheaders columnheaders using 1:2:3
with image title ""

Where the input file is:

,One,Two,Three
a,675.0, 1177.0, 1975.0
b,744.0, 13908.0, 20191.0
c,1767.0, 4374.0  ,5165.0
d,678.0, 1101.0  ,1888.0
e, 771.0, 13842.0 ,18648.0
f, 1372.0, 4264.0  ,5187.0
g,753.0 , 1541.0  ,1729.0
h,791.0 , 5832.0  ,20528.0
i,1310.0, 1225.0  ,5436.0
l,747.0,  1516.0  ,2118.0
m,825.0 , 16719.0 ,0
n,1341.0, 4427.0 ,9040.0


Any idea on how to improve this ?

Thanks !

Thank you for your reply

On ubuntu flags

LIBCERF_CFLAGS='-I/usr/local/include' \
LIBCERF_LIBS='-L/usr/local/lib -lcerf' \

are not required so that this might be an issue of my pkg-config setting.

However, looking into config.log, I found the following:

****************************************************************
configure:7376: checking for LIBCERF
configure:7384: $PKG_CONFIG --exists --print-errors "libcerf"
configure:7387: $? = 0
configure:7402: $PKG_CONFIG --exists --print-errors "libcerf"
configure:7405: $? = 0
configure:7481: result: yes

configure:9592: checking for memcpy

LIBCERF_CFLAGS='-I/usr/local/include  '
LIBCERF_LIBS='-L/usr/local/lib -lcerf  '

****************************************************************

On Ubuntu, pkg-config checks libcerf.
However, "-I/usr/local/include     -L/usr/local/lib -lcerf" is added to the many functions test.

Is the above intended?

Re: Logit scale? Was Re: New patch supporting nonlinear axes

Resent because of the limitation to 150k of the gnuplot-beta mailing list!

Dear Ethan,


I looked back at the data that I used when I was looking for a plotter which could do logistic scale.
It was before the new law on abortion (2001) which made legal the 11th and and 12th week of pregnancy.
But any cumulative distribution could be of interest.
I did not install yet the patch but a possible code could be (notice that “expit" is the standard expression for inverted logistic):
logit(p) = log(p/(1-p))
expit(a) = 1. / (1. + exp(-a))
set nonlinear y via expit(y) inverse logit(y)
plot [.001:.999] "Agegestationnel.txt" u 1:3 w l,"" u 1:4 w l , "" u 1:5 w l, "" u 1:6 w l,  "" u 1:7 w l, "" u 1:8 w l,  "" u 1:9 w l, "" u 1:10 w l,  "" u 1:10 w l,  "" u 1:11 w l,  "" u 1:12 w l,  "" u 1:13 w l
I can test it.

Here is what I got from Excel in year 2000!

I'm semi-blindly guessing.

If configure[.ac] finds out that cerf should be used, it adds
LIBCERF_CFLAGS to CFLAGS and LIBCERF_LIBS to LDFLAGS. Those CFLAGS and
LIBS are then used for all the remaining tests.

If that is indeed the case, I believe there are two "bugs":

- gnuplot should figure out that libcerf is not working and not add
those flags at all
- the flags should be added to the globas set of flags at the end, not
at the beginning of the configure script

I have confirmed the fix in the current cvs.

I have completely forgotten to build and install libcerf again.
Sorry for the noise.

However, why 

LIBCERF_CFLAGS='-I/usr/local/include' \ 
LIBCERF_LIBS='-L/usr/local/lib -lcerf' \ 

flags affect checking functions that are not related libcerf ?

The origin of the issue does not lie on the Cygwin but on gnuplot.

So I am back here.

See:
https://cygwin.com/ml/cygwin/2016-04/msg00202.html

Why adding 

LIBCERF_CFLAGS='-I/usr/local/include' \ 
LIBCERF_LIBS='-L/usr/local/lib -lcerf' \ 

flags affect configure process those are not related to libcerf ?

The initial character was the Windows <BOM> marker (Byte Order Mark)
that some Windows programs place at the start of a file to indicate that the
file contains unicode (e.g. UTF-8 or UTF-16) text.  Although the original intent
of the BOM was to make files more portable, in practice it has the opposite
effect  (as you found out)!

I have removed it from the cvs copy of win/gnuplot.iss
