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

changing the plot size doesn't change the size of the 'paper'.
instead, you may change the size when setting 'term':

set terminal postscript eps color solid size 5in,2.5in

Re: [Gnuplot-info] Vector Fields

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

the special filename "++" produces x,y-pairs, nothing more
(gnuplot manual, chapter 65.2.14):

-5 5
-5 4
...

to use these data for vectors you need to re-use the x- and y-data for the
direction data which is needed for a vector (x,y,xdelta,ydelta; see
gnuplot manual, chapter 44), here (x,y,xdelta=x,ydelta=2y):

plot ... using 1:2:1:(2.*$2) with vectors

to scale the vector length, scale xdelta and ydelta:

plot ... using
1:2:(0.5*($1)/sqrt(($1)**2+($2)**2)):(0.5*(2.*$2)/sqrt(($1)**2+($2)**2)) ...

'set table' gives plot coordinates, but not input data.

[Gnuplot-info] the gap between curve descriptions and main graph is so much

[netbaby <sut...@ya...>]

Dear all,
Would you mind if I ask you a question?
This is my GNUPlot script:

set ylabel 'Data (KB)'
set xrange [0:344.6]
set yrange [0:257.216796875]
set xtics 30.0
set ytics 30.0
set style fill solid 1.0
set key outside below
set boxwidth 0.4 relative
set arrow from 30, 0 to 30, 257.216796875 nohead
set arrow from 150, 0 to 150, 257.216796875 nohead
set arrow from 210, 0 to 210, 257.216796875 nohead
set term postscript eps color "Times-Roman" 14 solid
set term postscript landscape
set output 'uploaded_topten_peers.eps'
plot "dataStatistics" using 1:7 t "total" w lines, "uploadedToptenPeers"
using 1:9 t "IP-8 (2.19%)" w boxes, "uploadedToptenPeers" using 1:8 t "IP-7

http://old.nabble.com/file/p32958559/uploaded_topten_peers.eps
uploaded_topten_peers.eps 

Please have a look on my figure and script.
I don't know why my curve descriptions (items at the bottom of figure) have
a big gap with the main graph. I want those descriptions locating nearer
from the main graph. How can I do?

Thank you very much.

[Gnuplot-info] Parameter variation with gnuplot

[<bos...@gm...>]

Hi everybody!
I want to plot the function f(x)=a*x^2+b*x several times - each time with a different set of parameters. The parameters are stored in a csv file.

Does anybody know how to do that? I wasn't able to figure it out with the gnuplot docs.

Thanks for your help!

[Gnuplot-info] mouse and pixel value

[<she...@be...>]

Hello GnuPloteers

I did not get a response to previous post on this topic so I thought I
would try again but with greater detail.

I have written a little gnuplot script that plots a 2D gray-scale image
of the data contained in the file g_mag.dat. Here it is:

set ticslevel 0.0
set xlabel "x"
set ylabel "y"
set nokey
set size ratio 1
set autoscale
set pm3d map
set palette gray
splot 'g_mag.dat' matrix

When this script is run the GnuPlot window reports (in the lower left
corner) the pixel position of the cursor as the mouse is used to move
it. In addition I would like the value of the pixel at the cursor position
to be reported. How can I do this?

Thank you,
Daniel





 How can I get gnuplot to report the gray-scale value at a
point in the image when I position the cursor at the point?

Thank you!

Re: [Gnuplot-info] Outputting Coordinates

you need to plot something out of (y-)range to get the xtics labels
at the right positions.
then you plot a large black point shifted to the left and on top
a slightly smaller colored point.
the same applies to the points which a shifted to the right plus
errorbars with point size '0'.

reset

set xrange [-1:3]
set yrange [0:25]
unset bars
xoffset=0.2

plot "ts.dat" using 0:(-999):xticlabel(1) every 2 notitle, \
"" using ($0-xoffset):2 every 2 \
   with points pointtype 7 pointsize 9 linecolor rgb 'black' notitle, \

Re: [Gnuplot-info] Create non-bar chart with categories on x-axis

[D K <can...@ya...>]

Dear Walter

Thank you very much for your quick reply. The trouble is that I would 
prefer not to use boxes at all, certainly not for the single values I 
have to plot. I think the plot would be much clearer if I used points 
(and maybe error bars or lines) only.

Thanks again!

[Gnuplot-info] Create non-bar chart with categories on x-axis

[canavanin <can...@ya...>]

Hi everyone

I need to create a graph showing pairs of value. One item from each pair is
a single value, the other one is supposed to show a range of values (my idea
was to plot the mean value with error bars to indicate the range's max and
min, but I'm open to better ideas). The x-axis has no purpose other than
giving the names of the various categories (just like in a histogram) - all
that matters are the y-values.

I am pretty sure I could create something like this (value pairs and
x-categories) using histograms, but boxes just strike me as wrong in this
case. 

Is there a way to create such a graph? If so, could you please point me in
the right direction? 

Thanks a lot for your time!


PS: I have already asked this question on stackoverflow, but I guess it's
not really the right forum for gnuplot questions. There, however, I have
also included a rough sketch of my desired graph, and some further details.

[Gnuplot-info] SAME PROBLEM!!

[Pietro D. <pie...@gm...>]

János Löbb i have the same problem.... have you solved it?!

Re: [Gnuplot-info] can't set border linewidth for bars of rowstacked histogram

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

the thickness of the border is the same as the thickness
of the used linetype.

when using gnuplot version 4.4.x you may define linestyles
which are used instead of the built-in linetypes:

set style increment userstyles
set style line 2 linewidth 4

this changes the width of the border of style '2' to '4'.
so you need to do this for each linetype/style.

gnuplot 4.5 has a new command for doing this:
set linetype

[Gnuplot-info] can't set border linewidth for bars of rowstacked histogram

[mvampire <ove...@ya...>]

Dear all.

I'm plotting a histogram using gnuplot. And would like to set width of all
bar borders.

I set style of my histogram bars using:

'set style fill solid border -1'

after it I would like to set 'linewidth' for border, but 'set style fill
solid border -1' has no 'linewidth' option.

Do you know any solution for this problem? Maybe there is another way to set
border width for histogram bars?

Thank You in advance,
Kind Regards,
Andrey.

Thank YOU for the site. I've noticed it is aging a little, but it has
been a tremendous help to our users.

I could easily provide a place to host the site if you want to move it,
and I'd be happy to do so. I think the more "right" thing to do, if
you're ammenable, would be to add it to SourceForge/www.gnuplot.info so
it remains available indefinitely, and can continue to be updated and
supported by everyone working on gnuplot. I don't have access to SF,
though (Ethan?), so if that doesn't work out, I can post it elsewhere.

And since it's tangentially topical, another very useful site I've
discovered, that doesn't get as good a search ranking as it ought:
	http://www.phyast.pitt.edu/~zov1/gnuplot/html/intro.html
(Zoltán Vörös, if you read this list, would you mind contributing
some of those as demos?)

Re: [Gnuplot-info] Gnuplot and Qt

[karlahund <kar...@we...>]

Thanks for your answer.
qwt is probably not the solution for my tasks, because I need to plot files
in the 3-dimensional space. This works fine in gnuplot and I really like to
stay with this tool. 

Has anyone ever tried to "include" gnuplot in another software's window?
Doesn't have to be QT...
It would be helpful just to know wether it's possible or not... 

Cheers

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

Please someone save it! It has helped me ALOT when learning gnuplot and I
think than the learning curve will steepen for new users if it is not
available. I would also like to take the opportunity to thank Mr. Kawano
for the effort put into the website! I'm sure it has helped alot of people.
Thank you!

[Gnuplot-info] cursor and pixel value

[<she...@be...>]

Hello GnuPloteers

I have written a little gnuplot script that plots a 2D gray-scale image
using splot. How can I get gnuplot to report the gray-scale value at a
point in the image when I position the cursor at the point?

Thank you!

Hi,

for those getting in panic with the prospect of the not-So-FAQ
disappearing, you can save a copy for yourself (just 4.5MB):

wget --mirror -E -k -K -p http://t16web.lanl.gov/Kawano/gnuplot/index-e.html

Of course, it would be great if s.o. could host it (and hopefully
update it as well).

Cheers,
Jefferson

Great! Thanks a lot. Maybe a reference to this use of using + ternary
operator could be placed in the "range" documentation, as it probably is
the first place people will look for when trying to do this. That's what I
did, at least...

Thanks again

It might be a good occasion to announce about the site, 
http://t16web.lanl.gov.Kawano/gnuplot/

I have not been able to update this site for a while due to some local
issues, and finally I was told that this web server will be terminated
soon.

If someone can host/continue updating the not-So-FAQ, I would
appreciate. Or, I probably simply give up.  I have a personal web
server at home, but the access is too busy to process by a DSL line.

Thank you,
Toshihiko

Re: [Gnuplot-info] Assigning values to datapoints

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

does your 'awk' generated file contain valid 'set' commands?

where do the 'countrynames' come from? from your datafile?
if so, it would be easier to use an actual version of gnuplot and
plot 'with labels'.

you may exclude data from the fit with the 'using' option:

fit [1:100] f(x) 'datafilename' using ($1>10&&$1<20?0/0:$1):2 via ...
