I am using qt4.  QtCore does not seem to exist in the Ubuntu 14.04 
packages for qt5.

lrelease version 4.8.6

This seems to be related to qt.  See my previous message about set terminal.

That was a different problem altogether.  The executable was installed
in the wrong directory.

That patch was a non-starter because it totally broke on OSX and
basically just papered over the symptom by not checking for a problem
with the font request - so no error message but also the font +
scaling was still messed up if the system didn't respond in time.

I remain dubious that this is really a problem on the gnuplot end.
The font request really is delayed or late, which points to an issue
with font configuration at the operating system level. The identical
gnuplot code works fine on other linux machines.  That doesn't rule
out the possibility that something could be done in gnuplot to reduce
the chance of triggering an error in the font support, but so far I
have not seen a plausible suggestion as to what that change might be.

Out of curiousity, are you using Qt4 or Qt5?  Which exact version?

On Ubuntu 14.04,

works, all plots are correct.

Warning: slow font initializationHit return to

The first plot is wrong and all others are correct.

So, the problem is with the qt terminal, not the x11 terminal.

Sorry for the confusion.

Re: [Gnuplot-info] Gnuplot 5.1 Warning and Incorrect Plot

[Thomas D. D. <to...@sp...>]

I removed gnuplot 5.1 and installed the Ubuntu package.

Now, electron.dem works.

But, the Ubuntu package is seemingly screwed-up.  Installing gnuplot 
does not work.  Installing gnuplot-x11 does not work.  Installing 
gnuplot-qt does work.

I use X, not the desktop.

I removed the ubuntu packages and manually cleaned-up.  apt does not 
remove /usr/bin/gnuplot.

I rebuilt and installed gnuplot 5.1.  It works great, except for the 
first plot.

This issue has been discussed repeatedly for both OSX abnd Linux.  A fix 
was proposed and it looks like it was not implemented.

Should I file a bug report?

So far as I know the error message means exactly what it says.
The request to the system for a font took so long that gnuplot
decided to stop waiting for it and tried to draw the plot with
only a guess at font information.  Because of this, the sizing
and placement of elements in the font is not correct.

This can happen if you request a font that has buggy metrics
(some very old *.ttf fonts for example), but can also come if the
font is not already in the system or per-user font cache and the
system is just plain slow in searching/loading it from disk.
In the latter case the problem should go away if you repeat the
plot sequence, because now it is in the font cache.

This seems to be a recurring problem on OSX, but I have only seen it
on linux if the font is being used for the very first time and 
therefore none of the font metrics are cached.

The first plot is over-zoomed so the title and labels are just off the 
display.  The next plot is correct.  If I do the plots manually, line by 
line, the first plot is still not correct.  But, if I issue the plot 
command again, I get a correct plot.

I have been long time only window user and became also Linux user very
recently.
(But I have experienced msys and cygwin.)

I have also Googled.

Does the below work? 
$ cmd=$(printf "gnuplot -e \"fileW='/dev/shm/waitingTime%d.txt';
fileT='/dev/shm/thinkingTime%d.txt'\" file.gnuplot" $1 $1); $cmd

I did not say the below works 

 gnuplot /home/yas/file.gnuplot $1

I have wrote some working examples. Did not you look those?

As far as I know, there are two ways to pass the parameter to the script.
The below examples were already written in separately, but I summarize in
one for the convenience.

****************************************************
1. Scripts are prepared to use parameters and initial values of them are
determined outside of script.

#test.gp 
set term pngcairo
set out 'paratest.png
plot a*x+b
set out 
#end of test.gp

echo "a=2;b=3;load 'test.gp'" | gnuplotcvs 

or
 
gnuplot -e "a=2;b=3;load 'test.gp'"

2. Prepare scripts using argument variable ($0, $1,... (ver. <= 4) or  ARG1,
ARG2, (ver.5)) and argument passed by command line

****************************************************************************
Note that command line options are changed at ver. 5.

Version 4
$ gnuplot --help
Usage: gnuplot [OPTION]... [FILE]
for X11 options see 'help X11->command-line-options'
  -V, --version
  -h, --help
  -p  --persist
  -d  --default-settings
  -e  "command1; command2; ..."

Version 5
$ gnuplot --help
Usage: gnuplot [OPTION] ... [FILE]
for X11 options see 'help X11->command-line-options'
  -V, --version
  -h, --help
  -p  --persist
  -d  --default-settings
  -c  scriptfile ARG1 ARG2 ... 
  -e  "command1; command2; ..."

The option to use call mechanism is added on ver. 5
 -c  scriptfile ARG1 ARG2 ... 

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

I show a example for ver.5

#calltest.gp 
a=ARG1; b=ARG2
set term pngcairo
set out 'paratest.png
plot a*x+b
set out
#end of calltest.gp 

gnuplotcvs -e "call 'calltest.gp' 2 3" # works on all version
or 
gnuplotcvs -c calltest.gp 2 3 # works only on ver. 5 or later

For ver.4 or before, ARG1 and ARG2 should be replaced by $0 and $1.

Note for call script for ver.4 or before,

 NOTE: there is a clash in syntax with the datafile `using` callback
 operator.  Use `$$n` or `column(n)` to access column n from a datafile
inside
 a `call`ed datafile plot.

The below examples are not strictly passing the arguments but practically do the similar thing.

#test.gp
plot a*x+b
#end of test.gp

$ echo "a=2;b=3;load 'test.gp'" | gnuplotcvs --persist
or
$ gnuplot -e "a=2;b=3;load 'test.gp'" --persist

You are confusing gnuplot script and bash shell command. 

#!/bin/bash declare that this file is bash shell script. You cannot  write
gnuplot command in bash shell script.

The call command is intended to call other script from gnuplot script file.

Input file is  a  gnuplot script file that one call from gnuplot script
file.

You wrote a input file as shell script. It is wrong usage for call command.

That statement makes no sense.  Why should difference of equipment be

Without the missing figure, that statement doesn't make sense.

Hi All,

I am a bit lost, I have two files which I have plotted (the figure below), these files are based in timestamp in the first column and the data in the second column. The problem is that these files have been created by two distinct equipments, so the initial timestamps are different. My question is I get moving the green line in the arrow's direction, the green line begin in the 1432566731 timestamp.

Thanks all

Re: [Gnuplot-info] Gnuplot text scaling problem on Windows

[Teodoro S. <Teo...@es...>]

Hi Tatsuro,

I already register the bug some days ago:
http://sourceforge.net/p/gnuplot/bugs/1613/

I cannot edit it now, do I have to register?
Maybe you could add the terminals affected and the fact that only happens with 125% enlargement.

Thank you for your tests.

Regards,
Teo

I have tested on pdfcairo, wxt, windows, qt, emf png and svg at the moment.
I did not tested epscairo postscript, canvas simply because I have forgotten to test on them.

Affected terminals
wxt, windows, qt

Non-affected terminals
png, svg, emf

pdfcairo does give a graph with your script.

I think that we should register the phenomena into the bug ticket.

Hello Tatsuro,

thank you for your quick reply.
When I tried to reproduce the error I found that I had a a comma at the 
end of the plot command, even though no more input was following. 
Gnuplot did not complain about it.
After I corrected the syntax, both ways to set the y range worked again.
I still don't know why the behavior was different but I regard this 
problem as solved.

I have tested on pdfcairo, wxt, windows, qt, emf png and svg at the moment.
I did not tested epscairo postscript, canvas simply because I have forgotten to test on them.

Affected terminals
wxt, windows, qt

Non-affected terminals
png, svg, emf

pdfcairo does give a graph with your script.

I think that we should register the phenomena into the bug ticket.
