Hallo Dieter,

Many thanks, your suggestion helped a great deal and got me to
dig more into gnuplot (I hadn't used much of the label command before).

When I leave out 'graph' in the 'at graph' part of the command I can
position the point better using the coordinates in the plot itself
(rather than window based coordinates?).

This also seems to be working just fine for 3D plots via splot as
all I seem to do is add a 3rd coordinate to the position.

thank again for the great help,

Esmail

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

Dear Esmail,
maybe "set label" can be your friend? See help set label how it works, in my 
opinion it would be best to place a point with an empty text at "position" and 
manually put a texlabel (if you want) in the vicinity of the point.
Hope this helps,
take care



Dieter

Example:

f(x)=x*x+0.5
set samples 1000
set grid
set xrange[-1:1]
set yrange[0:1]
set label 1 " " center front at graph 0.5,0.5 point pt 7 ps 1
set label 2 "Point" at graph 0.52,0.45
plot f(x) w l lw 2

[Gnuplot-info] putting a dot on a graph or surface to mark a spot - how?

[Esmail <eb...@ho...>]

Hello all,

(just discovered this group)

I am plotting some graphs and surfaces using gnuplot using plot and
spot. These are functions that I am optimizing. So far so good.

What I would like to do, but don't know how, is to place some sort of
a marker or circle on the graph or the surface to indicate the maximum
location found. Ie I would draw the graph or surface first, and then
mark/superimpose a marker to show the maximum spot.

Is there a way to do this? I've been using gnuplot itself for
a while, but I have no idea how to do this.

Thanks,
Esmail

ps: I am mainly using gnuplot version 4.2 patchlevel 4 under Linux.

[Gnuplot-info] reg-multiplot

[balaji n. <bal...@ho...>]

Dear users ! 

I would like to do multiplot 
my data is having same x value but different y values 
i would like to stack my plot one above the other in steps .,

is it possible to do with gnuplot

( that is xaxis is same and to stack the y axis for each data file one above the other .  ) 

regards 
balaji

set key rmargin
set multiplot
set size 0.55,1.0
set origin 0.0,0.0
plot sin(x) notitle
set origin 0.45,0.0

[Gnuplot-info] Help needed for plotting multiple plots side by side

[Schlupp <sch...@ya...>]

Hi,

I am trying to plot two plots side by side with one key for both plots. Both
plots should be of same size, the key outside the right plot. Now I'm not
quite sure how to handle this. My first guess was
'set multiplot layout 1,2'
but the result is in the attached jpg. The right plot has to share the width
with the key, so the plots are not equally sized.
http://www.nabble.com/file/p24716804/2plots.jpeg 2plots.jpeg 
My next guess was to set the size parameter, but the result was a
catastrophe, as I'm not familiar with it.
The final terminal should be pslatex, but x11 would be fine to have a quick
view at it.


If someone has an idea how to handle this I'd be happy. 
Reinhard

Re: [Gnuplot-info] splot, pm3d interpolate and cb assignment

i tried to reproduce your problem - but everything works as expected
(in gnuplot 4.3-cvs):

datafile 'ts.dat':
1 3 2 4
3 1 4 2
2 4 2 1
4 2 1 3

plot script 'ts.plt':
reset
set multiplot
set size 0.5,0.5
set origin 0.0,0.5
splot 'ts.dat' matrix u 1:2:($3*($1+$2)) w pm3d
set origin 0.5,0.5
splot 'ts.dat' matrix u 1:2:($3*($1+$2)):($1+$2) w pm3d
set pm3d interpolate 0,0
set origin 0.0,0.0
splot 'ts.dat' matrix u 1:2:($3*($1+$2)) w pm3d
set origin 0.5,0.0
splot 'ts.dat' matrix u 1:2:($3*($1+$2)):($1+$2) w pm3d
unset multiplot

results in this plot:

Re: [Gnuplot-info] To increase the number of colours in gnuplot

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

define your own line styles:
http://www.gnuplot.info/docs/node237.html
and use these instead of line types in the plot command.

[Gnuplot-info] To increase the number of colours in gnuplot

[balaji n. <bal...@ho...>]

Hi,
     I want to have around 40 plots in a single plot. I used multiplot and smooth csplines. But the colours are repeated after 8. How to increase it for 40 plots. I tried with HEX code. But I don't get it.

The script I used is as follows:

set terminal postscript solid color "bold" 7
set multiplot
set size 1,1
set origin 0,0

set size 0.4,0.4
set origin 0.05,0.1
plot "re31" u 1:2 title "res31: 0.05(2)" smooth csplines lt 1,"re36"  u 1:2 title "res36: 0.07(3)" smooth csplines lt 2,"re111" u 1:2 title "res111: 0.07(3)" smooth csplines lt 3,"re116" u 1:2 title "res116: 0.06(3)" smooth csplines lt 4,"re146" u 1:2 title "res146: 0.05(2)" smooth csplines lt 5, "re152" u 1:2 title "res152: 0.38(5)" smooth csplines lt 6,"re187" u 1:2 title "res187: 0.08(3)" smooth csplines lt 7,"re219" u 1:2 title "res219: 0.07(3)" smooth csplines lt 8,"re303" u 1:2 title "res303: 0.05(3)" smooth csplines lt 9,"re343" u 1:2 title "res343: 0.27(12)" smooth csplines lt 10,"re347" u 1:2 title "res347: 0.06(3)" smooth csplines lt 11, "re353" u 1:2 title "res353: 0.07(3)" smooth csplines lt 12,"re386" u 1:2 title "res386: 0.06(3)" smooth csplines lt 13,"re464" u 1:2 title "res464: 0.09(4)" smooth csplines lt 14,"re509" u 1:2 title "res509: 0.08(3)" smooth csplines lt 15,"re543" u 1:2 title "res543: 0.13(4)" smooth csplines lt 16,"re587" u 1:2 title "res587: 0.09(4)" smooth csplines lt 17

your data file is not in 'matrix' format, see:

'splot' without the 'matrix' keyword and see how

have a look at the section in the manual dealing

Well, I was wrong and I apologize. The problem only occurred with data columns of very large values, but it wasn't caused because those values exceeded a 32-bit integer. Instead, the problem was the "set ytics" command.

I had been using "set ytics 1 ..." to try to force only integer values. Seeing non-integer tics which the data is only integers in misleading and confounds viewers. What I was doing works great when the values are small but seems to go into a very long loop when the values are very large. I will now make my process a bit more elaborate and compute a proper tic interval.

Unless there is some other, more direct, way to specify that automatic tic marks should only be integers?

Integers have basically no relevance to gnuplot datafile reading. 
gnuplot reads floating-point numbers, not integers, from data files. 
You'll have to show a much more specific example to allow this issue to 
be addressed in any meaningful way.

[Gnuplot-info] some remarks on CVS version

[atoms.h <sto...@gm...>]

Hi all,

I've been using the cvs-version lately since there are some features which
are neccessary for data representation and while doing so I found some
issues which I like to articulate here so that there's a chance they will be
introduced (or  that someone will tell me what I'm doing wrong):

This mainly concerns the new 'object' styles 'ellipse' and 'circle':
For some plots we need circular guides in a otherwise cartesian plot. They
should be centered at the x-axis and simply draw an arc (0:180) and, of
course, should be circular with respect to the plot coordinate system.
After some confusion I can in some sense understand why a 'circle' will be a
circle on the print rather than on the plot however, I would have found it
more intuitive to have a switch to change this behavior. Nevertheless, the
'ellipse' - of which I thought would be the solution -  seems to be an
entierly different animal. It lacks an 'arc' specifier as well as I haven't
been able to display the actual ellipse with a line rather than the area.
So I would like to emphasize that with the given direction the 'circle'
object is taking the, 'ellipse' should at least have the possibility of
arcing and border display. However, maybe my point is convincing to decide
via an option whether the 'circle' acts as a circle with respect to the
print or with respect to the coordinate system of the plot.

Much regards and keep up the tremendous work!!!
thomas

p.s. i should add that - for now - the above relates to the x11 terminal

Re: [Gnuplot-info] plot distribution

the normalization factor needs to be know before you plot.

what you could do:

  http://gnuplot.sourceforge.net/demo_4.3/data_feedback.html
  (look for 'sum')
- calculate the normalization factor
- do the plot

e.g.:
set table
sum=0
plot 'datafile' using 1:(sum=sum+$1)
unset plot
print sum
plot 'datafile' using 1:(1./sum) smooth frequency with boxes

[Gnuplot-info] Maximum integer size

[CLOSE D. <Dav...@us...>]

On a Linux system running on x86 (32-bit) hardware, gnuplot is working
great. However, when I plot from a datafile in which some of the values
exceed a 32-bit integer, the plot takes 100% CPU and never produces a
graph. Is this a real limitation or is there a solution (short of using
a 64-bit machine)?

[Gnuplot-info] splot, pm3d interpolate and cb assignment

[atoms.h <sto...@gm...>]

Hey all,

I encountered a wierd problem. What I'm trying to do (and what partly works)
is a 3d plot with matrix data like

$ splot path matrix u 1:2:($3*(Interf($1, $2, 5, 7.0, 14.5))) w pm3d notitle

and my pm3d setting is

$ set pm3d interpolate 0,4

up to here everything is fine!
However, if I try to assign the cbaxis like

$ splot path matrix u 1:2:($3*(Interf($1, $2, 5, 7.0, 14.5))):(Interf($1,
$2, 5, 7.0, 14.5) w pm3d notitle

or any other variable while interpolating, the only thing gnuplot seems to
do is scaling of the cbrange while still plotting the z-value on the
cbaxis... If I don't interpolate everything works fine!
Any clues?

Re: [Gnuplot-info] plot distribution

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

first we need a function for binning the x-data, i.e. the
continuous x-range is split into intervals of size 's':
bin(x, s) = s*int(x/s)

then we plot:
plot "datafile" using (bin($2,0.01)):(10/300.) \
   smooth frequency \
   title 'smooth frequency' with boxes

explanation:
- the bin-function assigns the x-values within one interval
  (which has a width of 0.01 here) to only one x-value (the
  lower interval border)
- with 'smooth frequency' all the y-values of data pairs
  with the same x-value are added
- "10/300." is just a factor, you could use "1." then each
  data counts as '1'

Thank you.  That's exactly what I needed.

Re: [Gnuplot-info] EllipticK(k)

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

as far as i know elliptic functions are new in version 4.3-cvs.
which version are you using?

[Gnuplot-info] Plot within a plot--how to?

[Jeremy C. <jer...@gm...>]

I would like to have a plot within a plot.  I have a plot where I would like
to zoom in on one corner to show the detail, while still keeping the rest of
the plot.
In looking around it seems like I might be able to do this with multiplot,
but that seems to be used for putting plots side by side which is not what I
want.  Is multiplot the way to go or should I be looking at something else?
 Is there a demo describing ho to do this?

Thanks,
Jeremy
