[Gnuplot-info] mouse indicated coordinate always relative to a subplot on multiplot?

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

Hello Guys,

I noticed that the coordinate simultaneously shown on the screen as mouse
moves around is only based on one of the subplots for a multiplot. For
example, I draw four subplots on a multiplot, but as mouse moves, the
coordinate shown on the lower left bottom is based on the subplot at the
lower right bottom. How can I make the coordinate always be shown relative
to the subplot the mouse is on?

Thanks,

Sincerely,
Jon

[Gnuplot-info] how to fill background color of a label?

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

Hello,

I am trying to fill the empty space of a label with background color so that
it could appear before anything else, without being blocked by whatever
underneath it. I checked help set label, but didn't lead me anywhere. The
closest option is front, but it does not do what I asked for. Thanks for any
advices,

Sincerely,
Jon

Thanks!

So under version 4.4, what I want to do cannot be performed then?

Sincerely,
Jon

Re: [Gnuplot-info] variable defined from reading a file?

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

the current version of gnuplot is 4.4

versions up to 4.2.6 don't have the 'eval' command.

Re: [Gnuplot-info] variable defined from reading a file?

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

I might have missed several backslashes. After fixing that, there is still
similar complaints. I still tend to believe that eval command is not
recognized in gnuplot. I tried the test case

g = 'plot aaa.txt u 1:2 w l'
eval g

it complains

gnuplot> eval g
         ^
         invalid command

which seems to support my guess,

Jon

Re: [Gnuplot-info] variable defined from reading a file?

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

Thanks for the sample code. I tested it and get an error like

if (i==0) eval "plot 'ts.dat' using
(mu".i."=column(1),sigma".i."=column(2),0/0):(0/0)"
                   ^
         "ts.loop", line 2: invalid command

Seems that the current version of gnuplot does not recognize eval command?!
The version for my gnuplot is 4.2 with patchlevel 3

I did a google search, but does not lead me anywhere ...

Thanks for further information!

Jon

Re: [Gnuplot-info] variable defined from reading a file?

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

plot in a loop using the 'reload' command and store the mu and sigma values
in variables specific to each sub-plot:

file 'ts.plt':

###############
i=0
f(x,mu,sigma)=exp(-(x-mu)**2/2/sigma**2)/sqrt(2*pi)/sigma
load 'ts.loop'
###############

file 'ts.loop':

every ::".i."::".i." notitle, f(x,mu".i.",sigma".i.")" \

(mu".i."=column(1),sigma".i."=column(2),0/0):(0/0) every ::".i."::".i."
notitle, f(x,mu".i.",sigma".i.")"

i=i+1

start it with:

[Gnuplot-info] variable defined from reading a file?

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

Hello,

So far gnuplot has given me many surprises, and expanded my horizon how much
it can do. Now comes one more thing I am wondering whether gnuplot can do.

For example, I save mu and sigma in a file

#   mu   sigma
    0.1    0.1
    0.1   0.2
    0.1  0.3
   0.2   0.1
   0.2   0.2
...

I want to read the first line and assign them to two variables mu and sigma,
then plot

f(x,mu,sigma)=exp(-(x-mu)**2/2/sigma**2)/sqrt(2*pi)/sigma

and then read the next line and assign to mu and sigma, and plot the next
Gaussian distribution again

...

If this can be done, that would give great flexibility to gnuplot,

Thanks for any advices,

Sincerely,
Jon

[Gnuplot-info] Programmatic Gnuplot

[Brady M. <bra...@gm...>]

gnuplot-info,

I want to use gnuplot for plotting some numerical simulations I am
running. I am considering spawning a gnuplot process and sending
formatted output to the stdin of gnuplot. I kind of like this
situation b/c it keeps the computation and visualization loosely
coupled. However, I wonder if there is a better way to share large
arrays of data (a numerical grid) rather than formatting it and
sending it textually to gnuplot's stdin. Your thoughts?

Brady

P.S. I posed this exact question on #gnuplot on freenode, sorry if I
missed your reply there.

Re: [Gnuplot-info] how to execute OS command using gnuplot defined variables

use 'system' instead of '!':

[Gnuplot-info] how to execute OS command using gnuplot defined variables

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

Hello,

I am trying to do something like this

s=1
f1='../aaa/bbb_' . s . 'i.hist'
!vi f1
p f1 u 1:2 w l

The purpose to doing that is to see what's in the file f1 before drawing it
(for debugging purpose). However, it seems vi takes f1 as the file name,
instead of taking aaa/bbb_1i.hist as the file.

Any idea how to deal with this?

Thanks,
Jon

That's a packaging error by your Linux distributor.  The file is present 
in the packages produced by us.

So ask Fedora.

Re: [Gnuplot-info] random-points

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

check if the gnuplot package of your distribution contains
the file "random-points".

if you didn't find it, try
find / -name 'random-points'
(takes some time)

if there is nothing found download the gnuplot sources.
once unpacked, you will find the file in the 'demo' directory.

[Gnuplot-info] random-points

[CLOSE D. (DAE) <Dav...@us...>]

I'm trying to create graphs similar to those shown in the demo gallery 
cumulative smoothing. However, the example scripts given reference a 
file called random-points which is not supplied anywhere I can find. 
Without it, I can't be sure I'm using the examples correctly.

To work around the lack of that file, I've created a file with some 
random numbers in four columns. When I feed this file to the second, 
third, and fourth example scripts, I get something reasonably similar to 
the example graphs. But it doesn't seem to work for the first example. 
There, instead of the histogram, I get a number of horizontal straight 
lines the full width of the graph. I wonder what I'm doing wrong?

This is the gnuplot 4.4.0-5 RPM supplied with Fedora 14 (beta).

Thanks  Marek  for  Your  answer. I seem to have asked it a bit unpresize. I'd
need  an         automatic/computational  evaluation  where  two  data   plots
intersect or where the difference of the two has its roots. Reading it off the
plot is OK for a few plots but if You need   to evalutate a big load  of  data
it would be nice to have a program doing that for You.

Can that be done with gnuplot or any other linux tool?

Thanks for any help or hints.

Thanks Johannes and Thomas for Your answers.
I'm  wondering  though,  if  it is possible in Thomas' idea to have the x2tics
only appear where there is an xtic. Can the xaxis' and  the  x2axis'  tics  be
correlated in such a way?

[Gnuplot-info] how to optimze the automatic y-scaling for kdensity plots

Thanks a lot Thomas! It works great with GPVAL_Y_MAX, GPVAL_DATA_Y_MAX.

Though I came to another problem now:
When  using  the  kdensity smoothing the automatically chosen y-range is often
trice as large as the maximum of the plot. Is there  a  way  to  make  gnuplot
automatically  optimize  the  y-scaling  in  such  a  case? Setting it by hand
wouldn't be data independent.

[Gnuplot-info] How to find root or intersection of data plots

[<lyn...@fr...>]

Hello!


Is  there  a  possibility  to  determin  the  root  of  a  data  plot  or  the
intersections of two plots depending on the interpolation type that was chosen
for plotting? Is that possible with gnuplot or another free linux tool?
I know it is tricky to define the intersection points for data plots since the
intersection mostly depends on the interpolation type and is rarly exactly  on
a  data  point.  Still it is often necessary to estimate the intersection of a
data plot with another or with a function.
It would be already helpful to know the two data points in between  which  the
intersection  would  lie.  I  guess  for  the  problem  of  finding  the  root
(intersection of a plot with the x-axis) it would just be a problem of finding
the pairs of adjacent points where thy y-value chages sign.
Any  way to  do that with gnuplot or another tool? Still, having an evaluation
possibility depending on the gnuplot interpolation type (eg.  straigth  lines,
splines or kdensity) would be great.

Thanks for any help or hints about this.

[Gnuplot-info] Bessel functions

how do I get Bessel functions of arbitrary order? It seems that there is
