[Gnuplot-info] Call help with export script in Gnuplot 5.0

[dbrant <bra...@ho...>]

Hi Gnuplotters

For years i have used the following script taken from the Gnuplot In Action
book to generate my graphs:

save "$0.gp"	# Save commands to file
set t push		# Save commands to file
set t png $1	# Store current terminal settings
			# options from second argument
set o "$0.png"	# Set output file name
replot		# Generate plot
set o			# Restore output to interactive terminal
set t pop		# Restore interactive terminal settings

This could be invoked as:

call 'export.gp' 'myplot' 'size 160,100' 

With the advent of Gnuplot 5.0 this no longer works due to changes in
argument references from tokens $0 ... etc to string variables.

Unfortunately i cannot get my head around it by way of examples i have seen. 

Could anyone please  re-work the script to take recent developments into
account that i may understand use.

Regards, Dave

Re: [Gnuplot-info] Sourceforge error

Works for me (now). Perhaps a transient error?

[Gnuplot-info] Unicode Input in Gnuplot's Interactive Console (Windows 7, 64bit)

[Stefan K. <kr...@mp...>]

Dear List,
is it possible to input Unicode characters into the interactive console 
window of Gnuplot running on Windows (7, 64bit) by typing with the keyboard?

System:
gnuplot 4.6.3
Windows 7, 64bit
(I change my Keyboard Layout with Alt+Shift between English, German and 
Greek.)

Ιn the interactive console (wgnuplot_pipes.exe):
Terminal type set to 'wxt'
gnuplot> show locale
         gnuplot LC_CTYPE   German_Germany.1252
         gnuplot encoding   default
         gnuplot LC_TIME    German_Germany.1252
         gnuplot LC_NUMERIC C
gnuplot> show encoding

         nominal character encoding is default
         however LC_CTYPE in current locale is German_Germany.1252

If I have a UTF8 encoded file "greek-xlabel.txt" with one line:
set xlabel 'angle α'

gnuplot> load 'greek-xlabel.txt'
gnuplot> plot sin(x)

outputs a nice graph with the x label being correct "angle α".
Copying and pasting the content of the file "greek-xlabel.txt" into the 
console:
gnuplot> set xlabel 'angle á / °'
gnuplot> plot sin(x)
Unable to convert "angle á / °": the sequence is invalid in the current 
charset (UTF-8), falling back to iso_8859_1

gives me an accented a (á) and an error.
φ
If I switch my keyboard layout to Greek most of the characters are not 
interpreted correctly by the gnuplot console.
alpha shows as á(accented a), theta as è (accented e), φ as ö ... and so on.

So, in general my System and gnuplot are able to deal with UTF8/Unicode. 
But for quick plots I don't want to rely on \Symbol workarounds, or load 
'greeklabels.txt" workarounds.
I guess I have to somehow change LC_CTYPE. But I couldn't find an option 
in gnuplot.
In the gnuplot console: "set encoding utf8" and "set locale 
'Greek_Greece.1253'" lead to:
gnuplot> show locale
         gnuplot LC_CTYPE   German_Germany.1252
         gnuplot encoding   utf8
         gnuplot LC_TIME    Greek_Greece.1253
         gnuplot LC_NUMERIC C

But that does not help.

Any suggestions? Is this a problem of the gnuplot console under Windows? 
Is it a problem of windows?

Thanks in advance.

Ah. I had hyphens in my filenames. Removing them cleared that error, but
now I get:

warning: Skipping data file with no valid points

I tried a non loop minimal example to ensure it's not a problem with my
datafile:
stats 'file.txt' prefix "file"
plot 'file.txt' every::file_index_max::file_index_max

This works fine.

Is there a way to look at what a command expanded into after the variables
were substituted?

I use this construction in scripts myself, so I am sure there is no
such limitation in general. The prefix must conform to normal
limitations for variable names, however.  It cannot start with a digit
or contain punctuation marks.

I get  an "illegal prefix" error when I try this. It seems like it doesn't
like taking the prefix from a variable, but I can't find any discussion of
this on the web.

Any ideas?

files = "one two three four"

do for [name in files] {
	stats name.'.txt' using 1 prefix name
}

plot for [name in files] name.'.txt' every :: name."_index_max" :: name."_index_max", \
     for [name in files] name.'.txt'


But probably I would do it differently.  Something like

set for [name in files] arrow from name."index_max", 0 to name."_index_max", name."_max"
plot for [name in filex] name.'.txt' using 1

[Gnuplot-info] [gnuplot] Loop to plot max value

[Jacob G. <jac...@gm...>]

Hi list,

I have several datafiles, which I'd like to plot together on one plot as
smooth lines, but I'd also like to highlight each maximum

With one file, I'm able to do

    plot 'file' smooth csplines
    stats 'file'
    replot file every::STATS_index_max::STATS_index_max notitle

And get what I want.
I tried expanding this with loops:

filenames = "one two three four"

plot for [file in filenames] file.".txt" \
     smooth csplines

do for [n=1:4] {
file=word(filenames,n).'.txt'
stats file
replot file every ::STATS_index_max::STATS_index_max notitle
}

This plots the csplines fine, but when replotting, I get four occurrences of
warning: Skipping unreadable file "four"

It seems this is some sort of name conflict by reusing the variable files;
I was able to solve this by using a different variable, but I'd like to
understand what happened.

Even after changing the file name, I don't get four separate maxima.
Instead, I get the maximum from "four" plotted four times.

Is it possible to do this with loops or do I need to write one big plotting
command to do it all at once?

Thanks
Jake

That may be expected behaviour, depending on how you started gnuplot.

[Gnuplot-info] running *.plt from windows batch file

[Mátyás S. <ser...@gm...>]

Hi all,

I have a question: I would like to run a *.plt file using windows
scripting, i.e. using a batch (*.bat) file, and so I tried to do so, but I
experienced that after running the batch file, the command window, that
pops up does not close automatically, it keeps hanging there, and I have to
close it manually.
However, if I only use *.exe files in the batch, this cmd window closes
automatically.
I also included an exit command at the end of the batch file containing the
running command of the *.plt file, but it doesn't change anything.

Do you know how I could make that window close automatically?

Thank you!

Mat

Re: [Gnuplot-info] plotting very big values

[BBands <bb...@gm...>]

I'd let gnuplot mind the ranges for you.

set xrange [1:100]
plot x*x
pause -1
set logscale y
plot x*x
pause -1
unset logscale
set xrange [1:101]
plot x*x
pause -1
set logscale y
plot x*x

gnuplot will usually do a pretty nice job for you.

As I said, please keep replies to the list, so that others may benefit.

In this case, I do not know how you would plot percentages, so perhaps 
someone else can help (which is another reason for keeping replies on the 
list).

However, since you want to put percentages on the x-axis (strange place to 
put them), then I guess the x-scale is simply [1:100] or something; it 
depends on your data.

Sure, but the bigger numbers will squish down the smaller ones; try both, 
and see which you prefer.

Another trick I've used in that case is to take the square root of the 
value e.g. "plot datafile using 1:(sqrt($2))" or similar.  Of course, 
anyone reading the graph will have to know this...

If I had to do that, I'd use a log scale:

set logscale    y
set yrange      [0.1:1000]      # Shows "User" (and zero spam!) better

That's what I use for my graph on www.horsfall.org/spamlog.pdf for logging 
my mail/spam stats.

In your case, I guess it would be [1:1000000] or something.

Hello Ethan,

Thanks for this; it seems to work!

So, the expression
            ($3 < val ? -1 : 2)

means "if the number in column $3 is less than val then assign it to black
and if not assign to white"? I am not sure I understand the part after the
question mark (ternary operator)

Thanks again.

Out-of-range z values are assigned the limiting colors in the palette,

 set cbrange [0:1]

[Gnuplot-info] Plot matrix data using cut-off values

[George P. <gp...@bi...>]

Hello,

I want to plot a 3-column data file using a black-white color scale.

I was wondering what is the syntax that allows those values of the 3rd
column to be colored black if they are smaller than a cut-off value and
white if they are larger than the same cut-off value

The three relevant lines from my script are

set cbrange [0.0:1.0]
set palette defined (0.0 "black", 1.0 "white")
plot "rmsdist4gnu_scale_1_30000.dat" using 1:2:3 with image

I know that is the last line that needs a different syntax but I am not
sure what.

Many thanks in advance.

Odd; I never saw the OP's reply, so I'll reply this way instead.

And with all due respect in turn, I don't think you know anything of my 
programming background.  In the past 40 years or so, I've used something 
like over 40 languages, and that's counting all versions of FORTRAN as 
one, all assemblers as one, all LISPs as one, all BASICs as one, all 
ALGOLs as one, etc.

Oh, and I have written parsers, compilers, etc.

I thought I saw a reference to it on this very list, but from later mail I 
guess it could've been 5.0 instead.

Here's a couple of practical examples of why I think Gnuplot is doing it 
wrong (in the sense of not making it easy for the programmer, which last I 
looked is the computer's job).

My script that plots my daily health readings:

  # Dropped Weight, Girth, BMI and BMR etc until they change.
  #    datafile using 1:(@WEIGHT)	lt 8		title 'Weight (kg)', \
  #    datafile using 1:(@GIRTH):(@GIRTH-2):(@GIRTH+2) \
  #	with errorbars lt 7 title 'Girth (± 2cm)', \
  #    datafile using 1:(bmi(@WEIGHT)) \
  #	with lines lt 13 title 'BMI (kg/m^2)', \
  #    datafile using 1:(bmr3(@WEIGHT))/100.0 \
  #	with lines lt 3 title 'BMR/100 (Cal/day)', \
  #    datafile using 1:(@SYS-@DIA)*10/@HR \
  #	with lines lt 9	title '(Sys-Dia)/HR', \
  #    datafile using 1:(avg(@SYS, @DIA)*10)/@HR \
  #	with lines lt 5 title 'µ(Sys,Dia)/HR', \
  # Broken parsing needs a dummy line here.
  #
  plot \
    datafile using 1:(@SYS)	lt 1 pt 1	title 'Sys (Hg)', \
    datafile using 1:(@DIA)	lt 1 pt 2	title 'Dia (Hg)', \
    datafile using 1:(@HR)	lt 2		title 'HR (bpm)', \
    datafile using 1:(@SYS-@DIA)*@HR/100.0 \
	with lines lt 7	title '(Sys-Dia)*HR/100', \
    datafile using 1:(avg(@SYS, @DIA)*@HR/1000.0) \
	with lines lt -1 title 'µ(Sys,Dia)*HR/1000', \
    1/0 lt -1 notitle	# Dummy so I can move above around


My script that plots my daily spam load:

  #
  # Too small to be worth plotting.
  #    datafile using 1:($5)	title 'Proxy', \
  #    datafile using 1:($6)	title 'Pause', \
  # Need a line after a commented continuation line.
  #
  # Note that "User unknown/missing" doesn't trend, hence no lines.
  #
  # I also dropped HSR; my inbound mail is around 100/day, so the HSR
  # correlates with Spam anyway.
  #    datafile using 1:(hsr($8, $7)) lt 3 title 'HSR', \
  #
  # And Banner went out in sympathy.
  #    datafile using 1:($3) lt 9		title 'Banner', \
  #
  # XXX Should call 0.1 "epsilon" or something.
  plot \
    datafile using 1:($8-$7)	lt rgb "green"	title 'Rcvd', \
    datafile using 1:($2)	lt rgb "red"	title 'Reject', \
    datafile using 1:(max($7, 0.1))	lt rgb "dark-pink" title 'Spam', \
    datafile using 1:(max($4, 0.1))	lt rgb "yellow" with impulses title 'User', \
    datafile using 1:($9)	lt rgb "cyan"	title 'Sent'

The terminally-curious can see the results over at 
www.horsfall.org/gnuplot.html (updated whenever).

Given that the purpose of a computer is to make humans' lives easier, I 
would really like the ability to comment out a line /in situ/, and put it 
right back again.

That's great to hear.  Gnuplot 4.6 brought a lot of nice new features, I 
am sure (without having looked at those release notes) that gnuplot 5.0 
will be even better.

Just an idea: How about creating vector graphics and converting to PNG 
at the desired resolution?

[Gnuplot-info] High resolution terminal and boxes

[Mathias M. <mu...@ph...>]

Hi there,

I am curently tailoring some graphics which present data with boxes. However, I need the graphics to have a high resolution in png format.
My choice : pngcairo size 6000,3000

When plotting the data with boxes and fill pattern <n> the pattern is hardly to recognize, since it is too tiny. It almost vanishes. 
Is there an option to increase the pattern resolution? It would be shame if patterns are only available to plot sizes of 600x480 pixels.

I already roamed the internet without any result.



Many thanks for helping me,

/M

You can find packaged release candidates for version 5 on SourceForge.
-rc3 is very recent and will probably be the final version, with formal
release of gnuplot 5.0 at about year's end.
