Thank Tatsuro,

I have an issue with 
patch -p1 < ../gnuplot-5.0.0-tabulate.patch 
(Stripping trailing CRs from patch; use --binary to disable.)
can't find file to patch at input line 8
Perhaps you used the wrong -p or --strip option?

For Unixy environments, I have experiences for CYGWIN and Ubuntu.

1. Download source tar ball from SourceForge site.
https://sourceforge.net/projects/gnuplot/
Files -> (each version)

2. Extract source tar ball.

3. Read INSTALL file carefully and prepare dependencies (dynamic link libraries and development files.)

4. Apply patch with patch command
$ cd (source root directory)
$ patch -p1 < (patch file name)

5. Configure with properly setting environments variables

6. make  and make check.

If you have no experience with Unix build, please ask experts.

Thank,

Could you give the procedure to implement the patch ?
I have a fedora distribution.

Please see the reply by Karl Ratzsch in the patch ticket #694.
https://sourceforge.net/p/gnuplot/patches/694/

That is probably what you want.

No.
But you can apply the patch and build the gnuplot by yourself.

Re: [Gnuplot-info] table

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

If I understand the patch
#694 Add options to set table command 

set table "outputfile.asc" clip

should work, but I get me an error:

unexpected or unrecognized token

Is the patch implemented in Version 5.0 patchlevel 5?

Thank.

[Gnuplot-info] table

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

Hello,

I used to use set table to generate an output file.
However, in the file, I have the "i" (in range) and "o" (out of range)
data.

Can I get only the in range data?

I try [:] to set the range, but it does not work.

Thank.

This seems to be an unintended side-effect of adding optional support for
ansi color output using the dumb terminal.   As a word-around, disabling color 
support fixes it

 #define NO_DUMB_COLOR_SUPPORT    at the top of dumb.trm

I'll work on a more satisfactory fix and commit it after a bit of testing.

[Gnuplot-info] Another gripe about Gnuplot 5.2rc1 dumb terminal (multiple linestyles not working?)

[Craig D. <def...@bo...>]

It appears that the new dumb terminal doesn’t distinguish between line types.

This is the output from the dumb terminal, using PDL::Graphics::Gnuplot on one of our 
test suite cases.  First, Gnuplot 5.0.  Second, Gnuplot 5.2rc1.  

Aesthetically, I can see the advantage of using symbols for each line or for the
plus-dash style.  But the current code doesn’t seem to have any distinction between
different line types.

Comments?

(I can supply the Perl-generated gnuplot scripts on demand, but it should be clear from
context — these are very simple plots…)

Best,
Craig

Yeah, sorry. It was a debug statement that should have been removed
before commiting the the bug-fix.

[Gnuplot-info] 5.2rc1 - query about new echoes

[Craig D. <def...@bo...>]

I’ve been noticing that 5.2rc1 breaks PDL::Graphics::Gnuplot in a minor way, by echoing information about the terminal and its options after a “set terminal” is issued.  In particular, “set terminal dumb” now echoes “dumb x, y = 24 77” as well as the expected string beginning “Options are”… .

Is this intentional? If so, I’ll patch P::G::G to expect it.  If not, could it please be suppressed in the final release?

Cheers,

Re: [Gnuplot-info] Quit gnuplot when plot window is closed

[pjhoust <hou...@ro...>]

GIven: RHEL/CENTOS 6 with utilities xwininfo and xev

The following worked for me to create a window destruction notification
function within the script that I used to call gnuplot.  Call the function
with the name of your gnuplot graph window (yes, you have to name it and
make sure it's unique) and a process ID (usually that of the shell running
gnuplot) and background it.  When it detects that the given window has been
destroyed, it exits sending a SIGUSR1 signal to whatever PID you gave it. 
What you do with the signal is up to you but I just do a mass murder.


###############################################################################
#
# NAME
#   WinDestroyNotify
#
# SYNOPSIS
#   WinDestroyNotify WIN_NAME PID

# DESCRIPTION
#       Waits for X window given by WIN_NAME to be destroyed then sends

WinDestroyNotify() {
        local WIN_NAME=$1
        local NOTIFY_PID=$2
        local FIFO="/tmp/WinDestroyNotify.$$.fifo"

                WIN_ID=${BASH_REMATCH[1]}

        mkfifo $FIFO >/dev/null 2>&1

        while read line
        do
                [[ $line =~ Destroy ]] && exit

[Gnuplot-info] awk

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

Hello,

I would like to use BEGIN with awk to define the FS.
How can I do it?
I tried
plot "< paste " . ARG1 . "| awk 'BEGIN { FS = "," } !/^\#/  { print $1 } ' "

But it does not work.

Thanks.

Re: [Gnuplot-info] placing graph origin at exact location respect to other graph in multiplot

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

as far as I understand, and it looks like that gnuplot does not allow
other than screen coordinates for offset in the multiplot environment.
Probably it's not clear which coordinates it should take: the first
ones, the previous ones...?

Anyway, you could use the gnuplot internal variables GPVAL_...
"show var GPVAL"
With this you need to do some "little" coordinate transformations.
Maybe there is even a more elegant solution?

The following code should do what you're looking for...
You can actually skip all the lines starting with "print..."


### start gnuplot example code
reset

# enter the coordinates of the origin of the second plot
# i.e. coordinates with respect to the first plot
XPos = -10
YPos = 0

set multiplot

# your first plot
plot x

print "TermSize x,y: ", GPVAL_TERM_XSIZE, ", ", GPVAL_TERM_YSIZE
print "Term X: ", GPVAL_TERM_XMIN, " to ", GPVAL_TERM_XMAX
print "Term Y: ", GPVAL_TERM_YMIN, " to ", GPVAL_TERM_YMAX
print "Graph X: ", GPVAL_X_MIN, " to ", GPVAL_X_MAX
print "Graph Y: ", GPVAL_Y_MIN, " to ", GPVAL_Y_MAX

XScaling = (GPVAL_TERM_XMAX - GPVAL_TERM_XMIN)/(GPVAL_X_MAX - GPVAL_X_MIN)
YScaling = (GPVAL_TERM_YMAX - GPVAL_TERM_YMIN)/(GPVAL_Y_MAX - GPVAL_Y_MIN)
print "Scaling x,y: ", XScaling, YScaling

XMargin = GPVAL_TERM_XMIN/XScaling
YMargin = GPVAL_TERM_YMIN/YScaling
print "Margin x,y: ", XMargin, YMargin

XOffset = (XPos - GPVAL_X_MIN + XMargin)*XScaling/GPVAL_TERM_XSIZE
YOffset = (YPos - GPVAL_Y_MIN + YMargin)*YScaling/GPVAL_TERM_YSIZE
print "XOffset x,y: ", XOffset, YOffset

# your second plot, for example with reduced size
set size 0.4
set origin XOffset,YOffset
plot x*x

unset multiplot

### end gnuplot code

[Gnuplot-info] placing graph origin at exact location respect to other graph in multiplot

[Nunzio L. <nun...@gm...>]

Hi all,

is there a way to place a graph, in multiplot mode, with its origin at some
location expressed not in screen coordinates but in graph coordinates of
another, say master, plot?

Thank you very much,

N

[Gnuplot-info] pm3d plot color range setting.

[Saman Y. a. <sam...@ya...>]

Dear all,I have plotted dssp plot (dssp file generated via cpptraj) using gnuplot. Plot (dssp pm3d map) image link is attached here. I used following color range for number of data classes eight.set palette defined (0 "#000000",1 "#0000FF",4 "#00FF00",7 "#FF0000")I want to use/assign different color for each data series instead of color range. Kindly help me in this regard.

Re: [Gnuplot-info] Extract filename

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

Honestly, it's not thought through thoroughly. Just when trying to
extract the filename from the full filename I thought it would be nice
if in above example an expression something like |.*\\Data(.*)\.dat|
directly returned the "007". Well, now I have a rather compact solution.

On the otherhand, when creating a list of data files to be plotted it
would be nice if the search pattern in
  FileList = system(dir /B /S Data*.dat)
could be a bit more sophisticated than a simple wildcard. I know that
this is a Windows system command and gnuplot doesn't have any influence
on it. Although, gnuplot could filter it further and/or "distribute" the
files to sublists which are then plotted in a single plot or multiplot
environment. I need to find a practical example to illustrate. But
probably one can also find a solution with the already existing gnuplot
commands.
I guess a binary regexp test together with the ternary operator could be
quite powerful.
Well, as I said, it's not fully thought out...

Re: [Gnuplot-info] Extract filename

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

Thanks a lot, Thomas, that's probably the shortest and most elegant way
to do it.
I was not aware that recursive functions are possible.

The following code will give only the content of the wildcard in the
title/legend/key.

### start code
BeforeWC = "Data"
AfterWC = ".dat"
FileList = system("dir /B /S ".BeforeWC."*".AfterWC)
chop(fn) = strstrt(fn,'\')?chop(fn[strstrt(fn,'\')+1:*]):fn

Wildcard(fn) = chop(fn)[strlen(BeforeWC)+1:strlen(chop(fn))-strlen(AfterWC)]

plot for [FileName in FileList] FileName u 1:2 w l title
Wildcard(FileName) noenhanced
### end code

If anybody has again a smarter solution please let me know.

Are there any chances (now or in the future) to somehow use "Regular
expressions" in gnuplot?
Thanks, Theo.
