Re: [Gnuplot-info] change backgound in epslatex?

[Jefferson S. E. P. <st...@gm...>]

Sorry, I have no experience with epslatex. With "postscript eps" the
following works:

set object 1 rectangle front from -10,-1.5 to 10,1.5 fc rgb "black" behind
plot sin(x) linecolor rgb "white"

Hope that helps.

Hi,

sorry, but I can't reproduce your problem.
I'm using gnuplot 4.4 patchlevel 3, under linux.

[Gnuplot-info] Some problem met while first use of gnuplot

[Pan r. <pan...@gm...>]

Hi All,

I am a newcomer of gnuplot. I used the following commands to draw a graph:

gnuplot <<'EOF'
set term jpeg
set output "hello.jpg"
plot sin(x)
EOF

But I can't see x-axis and y-axis in the output picture and the back
ground is black rather than white.
I have no idea what is matter. Could anyone please help?

Re: [Gnuplot-info] change backgound in epslatex?

[Pau <vim...@go...>]

Thanks, but that does not really work with epslatex ... the labels
seem to be dark grey instead of white

But in any case I thought that the background color would be limited
to the plotting area, not to all of the plot...

Is it possible to, say, for instance, draw a black square that covers
all of the plotting area and then replot over that?

thanks

Re: [Gnuplot-info] change backgound in epslatex?

[Pau <vim...@go...>]

thanks!

Actually it also works with gnuplot 4.5 and epslatex

I have now only this silly question that the axes and labels etc are
gone, since they are in black... how do I change the colour of those
to, say, white, to make them visible?

thanks again

when using the terminal 'postscript eps' with the 'background'
option, then the background will be colored using postscript
commands, so the eps file will contain the background color.

but when using 'epslatex' the background will be colored using
latex commands, i.e. the eps file will not contain any background
color.

To: gnu...@li...


Hi,

I would like to assign a different line style to the first bar than to the
rest of the bars in the histogram. For this I use indices and the
newhistogram command. The problem I have is that the bars are not centred
at the tic marks, but offset by half the bar width to the right. This looks
ugly and I need to urgently resolve this.

here is the data file:

# set A
0 3.5241611 0.0227152


# set B
1 3.4974980 0.0250806
2 3.5143099 0.0287665
3 3.5097331 0.0305371
4 3.5412929 0.0294131
5 3.5442677 0.0299973

And here the gnuplot plot:

set terminal wxt
set xtics ("Bar1" 0, "Bar2" 1, "Bar3" 2, "Bar4" 3, "Bar5" 4, "Bar5" 5)
plot 'plot.dat' index 0 using 2 title '' with histogram,\
     newhistogram '' at 1, '' index 1 using 2 title '' with histogram,\
     '' index 0 using 1:2:3 ti '' with yerrorbar,\
     '' index 1 using 1:2:3 ti '' with errorlines

Anybody knows how to centre the bars under the tics marks?

Thanks for any help,
Alexander

[Gnuplot-info] change backgound in epslatex?

Hi,

I have done my homework and googled here and there and did not find
the answer...

How could I change the background of the plotting area from white to,
say, black? I do not mean the gnuplot window, but the resulting eps...

I am sorry if this is a trivial question...

thanks

with an actual version of gnuplot you have access to internal
variables like
GPVAL_X_MIN
GPVAL_X_MAX
GPVAL_Y_MIN
GPVAL_Y_MAX
...
(see 'show variables all')

you could do all the dummy plots before starting the multiplot
environment and store the x/y-ranges in local variables and
use these to set the x/y-ranges explicitly for each plot
later.

[Gnuplot-info] Autoscaling when plotting data and functions

[Paul W. <pau...@gm...>]

Hello Gnuplotters,

I want to plot a data file and a function.  My problem is that I want to
autoscale the axes, but just on the data in the file, i.e. the yrange should
not be scaled to the yrange the function requires for the given xrange, but
yrange and xrange should be solely determined by the data, and those parts
of the function off these ranges should be clipped.  I tried the yrange
writeback-plot data-yrange restore-replot function approach, but that
doesn't work nicely with terminal PNG.

Thanks for any advise,

Paul

[Gnuplot-info] recursion and segfaults

[Leo B. <l_b...@us...>]

Hi, I was playing around with using tail recursion to do looping in
gnuplot. The result are pretty good, but I do run across the following:

gnuplot> tr(x, s) = (x < 1 ? s : tr(x-1, s+x))
gnuplot> looptr(a, b, cmd) = (b < a ? cmd : looptr(a+1, b,
gnuplot> sprintf("%s;\nprint 'a=%g ', tr(%g,0)", cmd, a, a)))
gnuplot> eval looptr(20135,20155,"")
a=20135 202719180
a=20136 202739316
a=20137 202759453
a=20138 202779591
a=20139 202799730
a=20140 202819870
a=20141 202840011
a=20142
Process gnuplot segmentation fault

That is pretty decent, given that the non tail-recursive function

t(x) = (x < 1 ? 0 : x+t(x-1))

gives a stack overflow error for t(99). However, it just seems like bad
form for gnuplot to segfault.

Re: [Gnuplot-info] scatter plots with circles when term = aqua

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

variables containing information to calculate e.g. the xrange are created
during execution of the 'plot' command and are accessible afterwards
(see 'show variables all').

you need to do a dummy plot first to fill these variables, calculate the
symbol
sizes and then plot again.

e.g.:

set terminal push
set terminal dumb
plot ....
set terminal pop
scaling=some_factor*(GPVAL_X_MAX-GPVAL_X_MIN)
plot ...

[Gnuplot-info] scatter plots with circles when term = aqua

[fearless_fool <rd...@gm...>]

[Pardon if this is a repeat post.  I originally posted via
gnu...@li... but it never appeared, even after
registering to the list.  Let me know if I'm missing proper protocol...]

I have a pair of datasets that I want to plot as scatter plots, overlaid on
the same graph.  I want dataset A to be plotted using 8 point solid gray
circles and dataset B to be plotted using 12 point solid red circles.   And
my terminal is aqua.

So here's the rub: I cannot use 'with points' because aqua doesn't have a
solid circle in its symbol repertoire (at least, 'test' doesn't show one).

I may be able to use 'with circles', but I don't see how to set the circle
size properly. 'set style circle' would set the size for both datasets,
which isn't what I want.  I could add a third column to my datasets to
control the size, but then the size is in units of the x axis, and the x
axis scaling is automatically generated.

So: are there global variables that tell me the limits of the x axis and the
size of the plot?  If so, I could do something like:

 plot "-" using 1:2:(8*scaling) with circles lc rgb "#888888" \
        "-" using 1:2:(12*scaling) with circles lc rgb "#ff0000"

... or something like that.  Any pointers?  TIA.

Re: [Gnuplot-info] Issues with display of plots from gnu octave 3.6.0 in gnuplot 4.4.4

[Dr. I. D. J. <die...@t-...>]

Hi Arnaud,
at some point in time octave developers decided to implement a kind of meta-
language, a graphics interpreter that prepares the data for the actual 
graphical interface (gnuplot in most cases).

Therefore you are in the situation to have an interpreter that implements a 
(more or less) complete instruction set for the second interpreter which is 
gnuplot (AFAIK).

Unfortunately (AFAIK) there is no direct interface to gnuplot from within 
octave any more. The commands are not transparent, instead, you have to rely 
on what has been implemented by the octave developers (not saying they did a 
bad job, but they created a graphical language "above" all other graphical 
command sets of graphics interpreters that might be used by octave).

If you want to tweak your graphs to look like you really want them to look 
like it is best to write the data to be printed into a file (say, file "A") 
and write another file that is parsed by gnuplot itself (say, file "B") and to 
use the gnuplot command set directly within file "B" to print the data in file 
"A". It'll be hard to find someone to help you with analyzing what commands 
are actually sent to gnuplot from within octave and how they could be adapted 
from within octave to match your needs.

Hope this helps,
take care

[Gnuplot-info] Issues with display of plots from gnu octave 3.6.0 in gnuplot 4.4.4

[am304 <arn...@gm...>]

Hi,

I have been having some issues with gnuplot 4.4.4. Initially I thought these
were due to GNU Octave (3.6.0), which I was using to generate the figures,
but when I print the figures to jpg using the (octave) command print, the
end result is OK. The problem seems to be with the display on the screen.
The issues I have been having can be summarised as:

* the legend display is wrong, which is more obvious when the legend is
boxed
* the ylabel or zlabel text is displayed horizontally instead of vertically
* the grid lines are displayed as solid lines instead of dashed lines

For more details, see these 2 posts on the octave mailing list:;

* 
http://octave.1599824.n4.nabble.com/Unable-to-display-multiline-text-tp4407599p4410363.html
Unable to display multiline text 
* 
http://octave.1599824.n4.nabble.com/Boxed-legend-not-correct-size-tp4404592p4404592.html
Boxed legend not correct size 

Is it something that the octave developers are doing wrong when passing the
information to gnuplot or is there a problem with gnuplot itself? I am using
win xp 64 bit if that makes any difference.

Many thanks in advance,

Arnaud

Re: [Gnuplot-info] Bug with epslatex and background color when using multiplot?

[Patrik.Br. <pat...@gm...>]

I found a fix, but I'm still not sure why this happens, is it a bug or a
feature?
On the second graph, include the line

set grid front noytics nomytics noxtics nomxtics

and you can see all text and tics but you have no grid (which is what I
want).

[Gnuplot-info] scatter plots with circles when term = aqua

[Robert P. <rd...@gm...>]

I have a pair of datasets that I want to plot as scatter plots,
overlaid on the same graph.  I want dataset A to be plotted using 8
point solid gray circles and dataset B to be plotted using 12 point
solid red circles.   And my terminal is aqua.

So here's the rub: I cannot use 'with points' because aqua doesn't
have a solid circle in its symbol repertoire (at least, 'test' doesn't
show one).

I may be able to use 'with circles', but I don't see how to set the
point size. 'set style circle' would set the size for both datasets,
which isn't what I want.  I could add a third column to my datasets to
control the size, but then the size is in units of the x axis, and the
x axis scaling is automatically generated.

So: are there global variables that tell me the limits of the x axis
and the size of the plot?  If so, I could do something like:

 plot "-" using 1:2:(8*scaling) with circles lc rgb "#888888" \
         "-" using 1:2:(12*scaling) with circles lc rgb "#ff0000"

... or something like that.  Any pointers?  TIA.

Thanks. I updated my version to 4.4 and it works.
Thanks and Regards

It definitely is.  That version is nearly 8 years behind!

[Gnuplot-info] gnuplot does not recognize "set style data histogram"

[user12345 <spa...@gm...>]

I am new to gnuplot. Seeing online examples, I tried to use:
gnuplot> set style data histogram
                                 ^
         expecting 'lines', 'points', 'linespoints', 'dots', 'impulses',
        'yerrorbars', 'xerrorbars', 'xyerrorbars', 'steps', 'fsteps',
        'histeps', 'filledcurves', 'boxes', 'boxerrorbars',
'boxxyerrorbars',
        'vectors', 'financebars', 'candlesticks', 'errorlines',
'xerrorlines',
        'yerrorlines', 'xyerrorlines', 'pm3d'
Same error comes on using 'histograms' instead of histogram.
My gnuplot version is 4.0. Can someone suggest if this is a version problem?
Thanks.
