you forgot 'xtic':

plot 'mydata.dat' using (100.*$2/$6):xtic(int($0)%5==0?stringcolumn(1):"") t
column(2), ...

Re: [Gnuplot-info] gnuplot histogram xtic(1)

[janjust <tja...@un...>]

Hi Thomas, thank you for your suggestion but when I try that it aborts with
the following error:

plot 'mydata_mibench_CRC32.dat' using
(100.*$2/$6):(int($0)%5==0?stringcolumn(1):"") t column(2), 		for [i=3:5]
'mydata_mibench_CRC32.dat' using (100.*column(i)/column(6)) title column(i)
                                                                                               
^
"plot.gpi", line 34: Too many columns in using specification

my original line looked like this:
 32 i = 5
 33 plot 'mydata_mibench_CRC32.dat' using
(100.*$2/$6):(int($0)%5==0?stringcolumn(1):"") t column(2), \
 34         for [i=3:5] 'mydata_mibench_CRC32.dat' using
(100.*column(i)/column(6)) title column(i)

Any ideas?

On a slightly unrelated note: my posts still show as pending, 3 days
later... but I'm registered and can't tell that I have any formatting
errors. Thoughts?

Thank you for your help!
-Tommy

help splot example

at the gnuplot prompt will give you some basic information.
does your datafile contain empty lines when the x-value changes?

[Gnuplot-info] is there way to assume the box boundary fixed but let tics move?

[Jon <dev...@gm...>]

Dear All,

I have spent a lot time fixing the size of the boxes in the multiplot
environment. The issue is basically that for fixed box sizes, the actual
size to display a graph changes with say ytics width and lmargin. Using the
default, the very left boxes would appear smaller than the right boxes to
be displayed. I am wondering whether there is a way to fix the actual size
for displaying the graphs, but shift the tics position (which I don't care)
in default.

An illustration of my issue is in the attachment, note the left boxes have
different sizes and alignment. I need to very carefully adjust lmargin to
bring the boundaries back to good alignment and of comparative sizes.

Thank you very much for your kind help,

Sincerely,
Jon

[Gnuplot-info] gnuplot histogram xtic(1)

[janjust <tja...@un...>]

Hello everyone,
    I'm trying to generate a rowstacked histogram for various data points
My data snippet looks like this:

  1 #Gnuplot data
  2 Range Global Heap Stack Unidentified Total
  3 9999 4258 0 5740 0 10000
  4 19999 3236 0 6764 0 10000

and my script is attached, but the key line is below:

Well, 30 is rather enormously big for a little annotation.  At that 
size, your whole plot is only about 30 x 30 characters big. Your cbtics 
gobble up 20% of the width of the whole plot.

Somewhat obviously no.  You can't cut off 20% of the canvas width and 
keep the aspect of the remaining area the same.

If memory serves, 4.2 may not have supported 'set margin' in splots, yet.

[Gnuplot-info] cbaxis in given format and margin

[cédric o. <ced...@gm...>]

Hello,

It seems that the computed margins in gnuplot 4.2 (or in gnuplot 4.4 if I add
"Helvetica" 30 to the terminal options) do not allow the cbaxis to be
completely legible.

Note that I have prescribed a given (scientific) format to this axis.
Without this scientific format, the values on the cbaxis fit on the
final eps figure.

Is there a work-around that would keep the font size used in the
cbaxis as well as the aspect of the plot.

I have tried to set the margins but I did not manage. Is there any
important ordering of the commands?

Thank you by advance for any hint,

Cédric

Following is a typical script:

reset
set term postscript eps color
set output 'tmp.eps'

unset surf; set view map;
set palette defined ( 0 'blue', 250 'cyan', 500 'green',750 'orange',
1000 'red')
set palette rgbformulae 22,13,-31
set pm3d

set xlabel 'x'
set ylabel 'y'

set format cb "%-1.1e"  # <= scientific format
set cbtics 50

splot x*y

Hello,

I don't think using multiplot this way is an actual abuse, iirc I read
something about this usage in the documentation. I am dealing with
dozens of gnuplot files and so I have to stay with reusing code via the
load command (and that mean using multiple plot commands).

But anyhow, yes, in this way every single plot is treated independently,
so their colour is reset too. But may question is still, if there's an
option to set the linetype of contour lines explicitly -- like it is
possible for other plot/splot content (lines/surfaces).

I have already tried to insert other contour values to shift/increase
the linetype of the desired contour line to a number with appropriate
colour. But then I am struggling with extra, unnecessary visible contour
lines. Maybe there's an option to turn specific linetypes/contour lines
to transparent?

Many thanks,

Stephan

Re: [Gnuplot-info] How to put a particular value from the data file as lable

[Thomas S. <t.s...@fz...>]

plot nothing (0/0 = undefined) to store the value into a variable,
then use this variable for the title of the 2nd plot:

plot 'testbep.dat' using 1:(t=$2,0/0), \
'' using 1:2 with points pt 7 ps 1.7  title sprintf("BEP %01.2f",t)

the end_of_data "e" is only needed for inline data not
for data read from a file.

[Gnuplot-info] How to put a particular value from the data file as lable

[sergejzr <ze...@l3...>]

Hello Dear Gnuplot wizards!

I am quite new to this topic, but I am starting to like this software.  I
have some graph in mind and need your help to vizualize it! My problem:

I would like to put a single point on the plot and to give it a special
title, so right no it works like:

plot 'testbep.dat' with points pt 7 ps 1.7  title sprintf("BEP %01.2f",0.63) 

data file 'testbep.dat':
0.6285488958990536	0.6285488958990536

What I need is to take the number 0.63 directly from the data file, means
take the 0.6285488958990536, round it to 0.63 and put into title.

Any ideas, how to do it?

And maybe you can help me to solve the second problem.

What I actually would prefer, is to place both, the curve data and the point
data into one file.

This works:
######################
set xlabel "Recall"
set ylabel "Precision"
set xrange[0.0:1.0]
set yrange[0.0:1.0]
set key inside left bottom
plot "-" with linespoints notitle,  "-" with points pt 7 ps 1.7 title "BEP

and generates a  http://l3s.de/~zerr/example.pdf perfect picture 

But whenever I put the data part into extra file it says "Bad datat on line

[Gnuplot-info] Choosing linetype of contour plot lines

[murt <mu...@gm...>]

Hello everyone,

My rough setup is the following:

unset surface
set view map

set multiplot

set style data pm3d
set pm3d ...
splot DATA_A1, DATA_A2, ...
unset pm3d

set contour base
set cntrparam levels discrete VAL_B ...
splot DATA_B

set cntrparam levels discrete VAL_C ...
splot DATA_C

unset multiplot

This is working very fine to plot a map of data (DATA_Ax) and two
contour overlays from different data (DATA_B, DATA_C). But it shows,
that both single contour lines (VAL_B and VAL_C) were plotted in the
same linetype (and color too).

So my questions are: Is there a way to set explicitly the linetype of
following contour plot lines? Or is it possible to set a linetype bias
and increment for contour lines?

My actual gnuplot file(s) (each splot in above example is a "load" of a
generic gnuplot file) makes use of my own predefined linetypes. This
works very well for choosing linetypes for surfaced plots (w/ "hidden3d
offset ..."). I think I am looking for something similar for contour
lines.

I am using gnuplot 4.6 patchlevel 0 on arch linux.

I would be very happy if someone of you could help me with this
struggle.

Many thanks to everyone,

Stephan

Thanks Tatsuro,

I was hoping for advice how could I possibly build it under Cygwin with wx. Should I just download source and try or there is a better way.

I have other packages that use wx and all work great, so I wanted to avoid installing X server and use what I have if possible

[Gnuplot-info] gnuplot on Cygwin with wx

[<mat...@ma...>]

Hi,

I have current Cygwin and I build wx libraries in it. I build also wxpython also and matplotlib with wwagg backend, which works as expected from within Cygwin

As Cygwin's gnuplot version does not offer interactive plot window, I was wondering what would be proper way to build gnuplot on Cygwin and take advantage of wx libraries


Thanks in advance

Re: [Gnuplot-info] gnuplot tics

[Thomas S. <t.s...@fz...>]

'help plot using xtic' says:
   xticlabels(N) is shorthand for xticlabels(stringcolumn(N))
so you may use
   plot 'data2.dat' using 3:xtic(stringcolumn(1)." ".stringcolumn(2)) t col

to have the ytics start at '0' you need to set yrange, not ytics:
   set yrange [0:*]

column 3 has no header, you need to tell gnuplot to use
the header of column '2' instead:
   plot 'data2.dat' using 3:xtic(stringcolumn(1)." ".stringcolumn(2)) t
columnheader(2)
