[Gnuplot-info] pm3d map + contour lines

[fly a. <vic...@gm...>]

Hi all.
I want to have a colormap combined with contour lines on one plot.
But if I do that I also get the lines (not contour lines, but those I'd get
if I just did splot 'file' u 1:2:3 without any other options specified)
plotted, which I don't want. Is there a way to just have countours and
colormap?
What I did was:

set style data pm3d
set pm3d map
# unset surface
set cntrparam levels 5
set samples 10
set cntrparam levels 25
set samples 100
set contour base
splot 'filename' using 9:10:5 title ""

So if I do in the last line: with lines palette 
then I get the unwanted extra lines.
If I don't, then I only get colormap and no contours...
Hope I made it clear. Any ideas?

Yes.  In several different ways, to.  You don't say how you want it

plot or splot

There's an option /noend  you can give :

wgnuplot /noend commandfile.txt

- oh - seems you can also spell it -noend or  -persist these days.

It doesn't work quite the same as the x11 -persist option, but the
effect is similar. The plot window stays open, but you also get the
interactive window, with a prompt.


Interestingly,

 wgnuplot commandfile.txt -

seems to work *better*, because the plot window stays up, but you
don't get the interactive window in this case. Closing the plot window
kills the whole process.

[Gnuplot-info] Gnuplot in the batch mode

[Martin J. <mar...@ya...>]

Hello,

in order to be able to call Gnuplot from any program to diplay data I tried
the following simple model case at the command line:

>wgnuplot commandfile.txt

The file commandfile.txt contains the following single line:

plot sin(x)

The window containing the plot of sin(x) appeared for a fraction of a second
and disappeared. So I changed the contents of the file commandfile.txt to
the following two lines:

plot sin(x)
pause 10

The window with the sin(x) plot appears for 10 seconds and disappears.
During its display the window is frozen. I would like to snatch it, resize
it, move it around and keep it as long as I want to until I hit the upper
right corner. I cannot, it is frozen and it has a predetermined lifetime.

The idea would be to indicate the data file and prescribe whatever is to
happen with the data in the command file.

I run Windows 2000.

Can someone help?

Regards,

Martin

You don't.  gnuplot 4.0 has no means of generating file names for data 
or output files programmatically.  You have to script from the outside 
for this kind of work.  I.e. run it as a subprocess with redirected 
standard input and send it commands from a script written in some 
scripting language you like.

Never heard of that place.  You may want to consider using "official" 
download locations, preferably sourceforge.net, instead of somebody's 
private pages.

No.  You're just spoiled rotten by Microsoft's "user should never be 
expected to know what they're doing" attitude.  ;->

You got a text file, so why didn't you *read* it?  Or, better still, 
read one of README text files that accompany it?

[Gnuplot-info] Running in "batch"..

[Lenka <lea...@ya...>]

I am using GNUPLOT4.
I would like to generate a lot of files with extension jpg or wmf.
How to run a program in batch to generate

Any help will be really appreciated.

[Gnuplot-info] Can I include variables in plot titles?

[Tax, R. <rt...@qu...>]

Hello,

=20

I have a data file with wire caps generated by two different RC
extractors.  I want to generate a scatter plot and run a linear
regression on the data.   Here are the basic gnuplot commands that I am
using:

=20

gnuplot> f(x) =3D k*x

gnuplot> fit f(x) "wire.caps" via k

gnuplot> plot "wire.caps", f(x)

=20

The above commands generate a plot with the data points from file
"wire.caps" along with the line f(x).  By default, the least squares
line has the label "f(x)" on the plot.   Given that the computed slope k
is an important parameter in interpreting the plot and it will need to
be used in other tools/analysis, I want to include the value of k on the
plot.=20

=20

gnuplot> show variables

=20

        Variables:

        pi =3D 3.14159265358979

        k =3D 1.40150928555715

=20

The fit command defined the variable k with the value determined by the
linear regression fit as shown above with the "show variables" command.
Instead of labeling the LS line with the default label "f(x)", I would
like to label it with "f(x) =3D 1.401*x".  I'm looking for something
similar to an sprintf function where I can generate the string "f(x) =3D
1.401*x" and then use this as the title of the LS line on the plot
command. =20

=20

While I'm a relative novice at using gnuplot, I could not find any
mention or examples of doing this sort of thing.   I would think that
labeling a plot with calculated data would be something that gnuplot
users would want to do.   Can I get gnuplot to label my LS line with
"f(x) =3D 1.401*x" where the 1.401 is the value of k generated by the =
fit
command in the gnuplot command file generating the plot?

=20

BTW, I'm using the following version of gnuplot:

=20

        G N U P L O T

        Unix version 3.7

        patchlevel 1

=20

While we don't have the latest version installed, I did search the
latest on-line gnuplot documentation and FAQ at http://www.gnuplot.info
<http://www.gnuplot.info/>  which no success.

=20

Thanks,

Rick

gnuplot 4.0 basically didn't change since its release almost 2 years 
ago.  Your Linux distribution did.  You guess whom that makes the more 
likely culprit...

> Does anybody know what's wrong ?

In the case we analyzed this, KDE is.  More particularly, the "klipper" 
process is interacting badly with gnuplot's way of handling the X 
cut'n'paste mechanism.  It turns that both KDE and gnuplot are acting in 
slight disagreement with the X11 recommendations for cut'n'paste, such 
that if you combine the two, klipper will spend excessive amounts of 
time asking the X server for the data gnuplot offered.

The next gnuplot release will probably fix this.

[Gnuplot-info] gnuplot 4.0 / Ubuntu: Xorg uses a lot of CPU

[Thierry B. <ti...@in...>]

Hello !

I have compiled gnuplut 4.0 on Ubuntu (5.10 Breezy) . Then when I use 
gnuplot (with its terminal X), the Xserver (Xorg) works a lot (Intel 
Xeon 2.8 GHz). It becomes actually hard to work with other applications.

Note that the problem appears as soon as gnuplot open its X terminal and 
doesn't depend on the amount of data which has to be plotted.  It 
disappear as soon as  I destroy the window.

I use gnuplot since more than five years on linux and I have never had 
this problem.

Does anybody know what's wrong ?

OK, seems that I have to extract the records into a single file.

As long as you keep using a scanf() format string, I suspect you can't, 
because among other effects, that introduces a difference between the 
column number counts you have in "using", those in the actual file.  In 
a nutshell, that scanf format strips the first column out of your file.

[Gnuplot-info] keys of stacked histograms

[Daniel G. <li...@da...>]

Hello,

the documentation for the new features is not that clear, or I did not understand it..so please give me a hint.

My Datafile format looks like this:
BHR 0 14 21.5385 19 113 0
BHR 1 14 21.5385 27 318 39
BHR 20 10 15.3846 24 190 211
BHR 50 12 18.4615 19 103 101
BHR 70 4 6.15385 4 30 23
BHR 90 1 1.53846 1 11 10
BHR 100 10 15.3846 10 17 17

my plot is:
plot  "file1" using 3 "BHR %lf %lf %lf %lf %lf", \
      "file 2" using 3 "BHR %lf %lf %lf %lf %lf"

The third column are percentages, they sum up to 100. As keys for the different colors I want the first column. Labeling the x-Axis is no problem (took it from the examples), but how can I specifi the first column as key description?

Thanks for answering,
Daniel.

[Gnuplot-info] Re: AW: Re: custom borderstyles in histograms

Hello,

Is the described behaviour a bug?? Should I  submit a bug report?

Regards,
Daniel.

--------------------------------------
Here is a simple example for this problem:

set style line 1 lt 1 lc rgb "blue" lw 1
set style fill solid 0.2
plot sin(x) with boxes linestyle 1

produces boxes with no border, but blue border is expected.

set style line 1 lt 1 lc rgb "blue" lw 1
set style fill empty
plot sin(x) with boxes linestyle 1

produces boxes with background color, i.e. nothing can be seen but blue lin=

[Gnuplot-info] color mixing in pm3d map

[dups <nic...@vo...>]

Hello
I would like to splot a map in pm3d with this kind of file:

x y  R1  R2

0 0 0.2 0.8
1 0 0.3 0.7
2 0 0.5 0.5
...
0 1 0.4 0.6
1 1 0.3 0.7
2 1 1    0
...etc
In this file R1+R2=1 (all the time)

I would like to attribute a different color for both R1 and R2 columns.
For example if I attribute red to R1 and yellow to R2 and that I plot 
 the point defined by third line of the example (2,0,0.5,0.5) the result 
should be orange at the point x=2 and y=0.
Is it possible to do such a map??
I hope I have been clear enough..
