[Gnuplot-info] How to desactivate the option which shows the coordinates (x,y) of the cursor in lower left corner

[Cong-Liem T. <cl...@um...>]

Hi,

My problem is the following: when I send a copy of the graph to the
clipboard and paste it into WORD, the coordinates (x,y) of the cursor in =
the
lower left corner also appear in WORD.

How to desactivate the option, if any, which shows the coordinates (x,y) =
of
the cursor in the lower left corner in the Graph window before I send a c=
opy
of the graph to the clipboard?

Best regards,

Re: [Gnuplot-info] 2y-axis problem

[Dieter J. <die...@t-...>]

Hi Torbjorn,
you should take a look to "help plot" on the commandprompt of gnuplot.
plot XYZ using ABC axes x1y2
might help you. You should really spend some time to look into the docs.

Take care

You complete neglected to show how you came from those data to the plot. 
    I.e. which commands you gave to your gnuplot.  Without that 
information, it's quite impossible for anyone to offer meaningful help.

Also note that your gnuplot executable is quite outdated --- 3.7 has 
been replaced by 4.0 18 months ago.

[Gnuplot-info] linear regression

[Gavin B. <gav...@ya...>]

If I understand you properly then all you want is to
plot the data and fit a straight line. This is easy in
gnuplot.

you can set your xrange and yrange to be whatever you
want - 

set xrange[0:*]
set yrange[0:*]

if you just want your axis to cross at the 0,0 point.
See help xrange.

You can also fit your data using:

fit m*x + c 'data.dat' via m,c

which will find the values of m and c that match your
data best: type 'help fit' for a description of what
this does. You can then plot it using

plot 'data.dat', m*x + c

column 1 is y axis data, 2nd column for x axis. The resultant graph shows the
intercept as being the first data point, 0.005, 0.47!

The x axis shows tics of values 5, 10, 15, 20, 25, when the above data is not
within this range. Y axs shows tics in the right range to the data.

I want to add a trend line to the function f(x)=mx+c for the above data and also
deduce values for the intercept and the slope of linear regression.#

Any help?

[Gnuplot-info] finding outliers

[Astan C. <st...@al...>]

Hi,
Thanks for the info on drawing circles in GnuPlot. It was much appriciated.
Anyway, I was just wondering if GnuPlot has a function to calculate 
outliers from a given dataset (in a file specifically). Im rather new 
and dont know much about all the built-in functions in GnuPlot.
Thanks for your help
Cheers

[Gnuplot-info] palette with pm3d.

[Patricia A. <am...@ib...>]

Hello,

I am using pm3d to generate contour plots. I have data from -1 to 1 and 
so I used
cbrange and palette with gnuplot version 4.0.
set palette defined (-1.0 "blue", -0.5 "green", 0.0 "yellow", 0.5 
"orange", 1 "red")
But I only get these 5 colors on the plot. Is there a way to have more 
subtle changes
(i.e. between -1 and -0.9 have a different blue etc...).
I tried rgbformulae but it did not help.
thanks in advance,

Patricia

Re: [Gnuplot-info] Plot Background Color

If that line didn't cause you an error message, your gnuplot executable 
was built with the old-fashioned, direct PNG driver.  Bad idea.

Get and install libgd, then rebuild gnuplot, so you get the "real" PNG 
driver of version 4.0.  Then read 'help png' carefully and you'll find 
how to set the background colour.

[Gnuplot-info] Plot Background Color

[Raj S. <tor...@ya...>]

Hi Group Members,

I needed some information regarding how to set the
background color of a GNU plot when using "plot"
command. 

The details of my environment are as follows:

gnuplot version: 4.0 
machine details: Sun Solaris 

Options used by me:
  set terminal png color
  set grid

I am searching for option(s) that sets the background
of my plot to Gray colour. Kindly provide me with the
information regarding this. 

Also, I am not subscribed to this group list and reply
me to this email id (tor...@ya...) only. 

Thanks & Regards
Raj Sekhar

[Gnuplot-info] A question about the floor() function...

[<Gur...@ao...>]

Hi everyone, 
 I have a question about the floor() function in gnuplot.. It seemed  to me 
as if floor() function only works for values where the mantisa is less  then 
2^31 .. Is this the intended behavior ?
See below:
 
gnuplot> print floor(2147483648.52366)
-2147483648
gnuplot>  print floor(2147483647.52366)
2147483647
gnuplot> print  floor(2147483649.52366)
-2147483648
gnuplot>                     
 
This also spins out another question. Is it possible to define any  variables 
as "unsigned" in gnuplot?
I am using a precompiled windows binary for gnuplot 4.0 that i downloaded  
from gnuplot website.. (gp400win32.zip) 
I did search the mailing list archives before this email for "floor" but  
couldn't hit anything related to this.
 
Thanks.

You can't.  Box width is a global setting --- its value can't be=20
selected differently for individual data sets.

Not particularly to reduce it, but to determine it.  Boxes can either be =

made to touch each other automatically by gnuplot, or have a width which =

you specify.  This width specified by you can be a constant number, or=20
it can be taken from the data file, such that it can be different for box=

In a minimalistic example:

	set yrange [0:*]
	plot '-' with boxes
	  10 1 2
	  20 2 5
	  30 3 1

[Gnuplot-info] thick dots or ..

[gnuguy <ber...@co...>]

I've got about 25 datasets I'd like to plot at the same time.
I've downloaded and installed the 4.1 code in order to allow me
to specify the color per line (PNG is output format).

In order to be able to visually map each graphed line to the key,
I'm using a variety of colors and two different widths.   It's getting
tough to tell some lines colors apart and would like to specify some
line types as dashed in order to make them easier to identify.

Is it possible to assign a dashed line a specific color?  If so,
how?

Is it possible to assign a dashed line a color and > 1 linewidth?
If so, how?

Other options?  Note that each dataset has 100s to 1000s of points so 
using linespoints makes each line a mess.

This is 4.1.

Thanks

[Gnuplot-info] strange segfault

[R P H. <he...@ow...>]

I have killed a day, trying to understand what I am doing 
wrong, but cannot figure it out.  I generate what I though 
were well formed driver files for gnuplot, and data files for 
each driver file to eat.  But I get this:

[herrold@centos-4 gnuplot]$ gnuplot gnu-BA.gnu

 	{the graphical display is fine - screenshot sample at:
 	http://www.herrold.com/gnu-BA.gnu-patched.png  }

The corrective patch (I think) is simply directing output to a

No.  I mean that's exactly what you can *not* do.  But you can turn of=20
gnuplot's automatically generated legend, and draw you own instead.=20
Manually, using 'set label' commands and maybe a 'set arrow' command to
draw a sample line.

One of

1) edit the PostScript after the fact
2) edit the PostScript on-the-fly, by sending 'set output' through a
    stream editing program
3) change the source and rebuild gnuplot.

RE: [Gnuplot-info] splitting the key in a graph

Thank you for your answer,=20

So if I understand well,  you mean that I can (say in a 2 curves plot) =
put
the title and the sample of curve n=B01 at position (x1,y1) and the =
title and
the sample of curve n=B02 at position (x2,y2). But can you tell me the =

to do it. (the user's guide don't mention it if I read it well).   =20

May I ask you one more question : I tried to color in grey a graph with =
the
'filledcurves' option. Since I work with postscript terminal, I used =
'lt 9'
to produce the color. Unfortunately, the grey produced is darker than =
the
grey I need for my publication. Can you tell me how I can obtain a =
lighter
grey.

Thank you very much for your help

None short of not letting gnuplot draw any legends, so you can paint=20
your own if and where you want.

Err, by sticking less text into it? ;-)

Seriously, the only generic way of doing that is to change the default
font of your terminal driver (at 'set terminal' time, typically). Or =
you
can use a driver that offers special text formatting (postscript=20
enhanced mode, TeX, recently some more).

[Gnuplot-info] Thank you and congradulations

Hi,
I am a Linux newbie, but your program has helped  me immensely in my
work (Bioinformatics).  I thank you from the bottom of my heart and hope
that you carry on with the good work.

In the page above there are one example that will probably help you to
draw a circle using gnuplot:
