[Gnuplot-info] Two input files, how to ratio of values?

[LukasP <LP...@po...>]

Hello,

let's have two datafiles, both have the same number of lines (and the same
first column):

A.txt:
1 10
2 20

B.txt:
1 11
2 30

And I'd need to draw a plot of ratio of y-values, so that x = {1, 2} (same
in both datafiles) and y = {11/10=1.1, 30/20=1.5}.

Is there a way how to provide this?

Cheers,

LuP

[Gnuplot-info] X11 Terminal with Scrollbars?

[<bai...@eu...>]

 Hi,

I am using "set term x11 size x,y" where y is larger than my screen height.
Now I would like scrollbars in the gnuplot window.
How can I achieve that? Thanks ahead for any help.

Re: [Gnuplot-info] How to plot directly in unit of pixels by gnuplot?

[Fayer M. <fay...@gm...>]

I have found the answer. This mail is just for anyone who has same
problem.

Gnuplot may not be a good choice for abstract coordinate plotting. For
such purpose, ImageMagick is a perfect choice. Of course, ImageMagick is
a far more useful tool.

To draw two stacked but non-overlapped rectanges, if one use PerlMagick,
a simple but fully functional sample code can be as below:


use Image::Magick;
my $o=Image::Magick->new;
$o->Set(size=>'10x10');
$o->Read('xc:transparent'); # canvas color
$o->Draw(primitive=>'rectangle',points=>'6,6
9,9',fill=>'hsb(16.6667%,100%,100%)'); # yellow
$o->Draw(primitive=>'rectangle',points=>'3,3
7,5',fill=>'hsb(16.6667%,100%,60%)'); # dark yellow
$o->Write('test.gif');

Re: [Gnuplot-info] limiting x range of data shown

[Junghun S. <jh...@ef...>]

Any number divided by zero is not plotted.

for functions:
plot (x<=3.5?x:1/0)

for data:
plot "data" u 1:($1<=3.5?$2:$2/0) w lp
(with "data" file like
1 1
2 2
3 3
3.5 3.5
4 4
5 5
)

Maybe there's a better way...

[Gnuplot-info] limiting x range of data shown

[Adrian H. <adr...@es...>]

  Is there a way to make gnuplot only show a limited range of data?  
i.e. I want the xrange to be kept the same (for example for 0 to 3.5), 
but only show data up to x=3?

Thanks

[Gnuplot-info] splot with non uniform data?

[Magnus E. <mag...@gm...>]

Hi,

I have a nice set of data (geographical coordinates (x, y) and
temperature (z)) which I would like to plot as a "heat map".

The problem is that the coodrinates are not arranged in a matrix but
are rather random.

Is it possible to use gnuplot to generate this kind of graph? I want
to intrapolate between the data points and extrapolate outside them.

Re: [Gnuplot-info] how to plot different values of a file with different color

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

instead of a histogram you may use boxes:

set xrange [-1:7] 
set yrange [-1.5:1.5]
set style fill solid 0.5
set palette defined (-1 "black", .25 "green", 1 "red")
plot "file1.dat" us 0:2:(0.5):2 with boxes lc palette notitle, \
"" using 0:($2>=0?$2+0.1:$2-0.1):1 with labels notitle

Re: [Gnuplot-info] fit and plot problem

So g(x,y) is not the function you actually want to plot.  You want to 
plot the implicit curve defined by g(x,y)==0.  Your best bet for that 
would be parametric mode, plotting a circle with the properties found by 
fit:

	set parametric
	set trange [0:2*pi]
	plot 'data.txt', xa+R*cos(t), ya+R*sin(t) title "fit"

Yes.  See "help set label", particularly its mention of sprintf.

No, you don't.  gnuplot is a program, not a storage facility.  So 
wherever it is you're actually saving those files, it's not "inside 
gnuplot".

Well, the message is pretty clear, isn't it?

There is no file that gnuplot can read with the name you told it.

[Gnuplot-info] how to plot different values of a file with different color

[mannu j. <man...@re...>]

Hi,



I have a file like this

file1.dat:

I 1

M 1

N -1

G 0

K 1

L 0.25

R -1



I want to draw histogram with different color for different values like for 1 it will come with red color, -1 will come with black color and 0.25 will come tilted and of green color (but the order in whatever way they are in file shouldn't change in plot). Does anyone have any idea how to do that?



Thanks,

set fit logfile 'Y:/User.ASH/controllo foratura SM ring/Pesatura

would type so much easier...

And if you put a

   cd 'Y:/User.ASH/controllo foratura SM ring/Pesatura 21_07/plots'

at the beginning of the file, you can save even more needless typing.

> set label 1 "Fitted Circle:\nR = R\nX_C = 0\nY_C = 0" at 390, -0.11, 0.375

You'll want to change that to get the actual fit results into the label 
string.

You're trying to use the 2D plot command to display a 3D function.  You 
want to use 'splot' instead.

Re: [Gnuplot-info] Single entry manipulation

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

you need an actual version of gnuplot (>= 4.4)
1st you do a dummy plot (plot nothing) to set a variable
which is then used in the 2nd plot.

plot "datafilename" using 1:(f=$1 , 0/0) every ::0::0 notitle, "" using
1:(f*$2)

[Gnuplot-info] Stacked bar charts in gnuplot 4.0

[Anshul V. <ans...@gm...>]

Hi,
I have a gnuplot version 4.0 installed in the linux machine. I need to
create a stacked bar graph with the same version. As I found out that style
histograms is supported in 4.4, can I have some workaround to do the same
with 4.0 using boxes?

I have data as below:

#Month    B8    8T10      A10
6             18     2           2
7             15     4           2
8              20    0           1


Thanks for your help!!

Thanks & Regards,

Anshul Vyas
