Re: [Gnuplot-info] Help request - linear regression giving screwy results

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

let's look at your data:

Dec2009 5.2
...
Mar2011 34.7

dates in gnuplot are calculated as 'seconds since beginning
of the gnuplot epoch' which is '2000-01-01 00:00:00'. so internally
your data are:

gnuplot> print strptime("%b%Y","Dec2009")
312940800.0
gnuplot> print strptime("%b%Y","Mar2011")
352252800.0

312940800.0 5.2
...
352252800.0 34.7

this means the slope 'm' of your linear regression function
f(x) = m*x + b
will be around
gnuplot> print (34.7-5.2)/(352252800.0-312940800.0)
7.50407000407001e-07

the y-axis intercept 'b' will be around
gnuplot> print 34.7 - 7.50407000407001e-07*352252800.0
-229.632967032967

thus the fit algorithm should make small steps in the 1.e-8 range
when varying 'm', but large steps in the 1.e-1 range when varying
'b'. this difference in step size makes it (nearly) impossible for the
fit algorithm to converge properly, so it will end up with a regression
function which crosses your data points but with a wrong slope.

a small step (1.e-8) which has a strong effect on 'm' has 'nearly'
no effect on 'b'.
and a step which has an effect on 'b' will - when applied to 'm' -
result in a regression function which misses the data points totally.
this behavior confuses the fit algorithm.

to make the fit algorithm happy, apply a factor of e.g. 1.e-7 to 'm'

f(x) = 1.e-7 * m *x + b

and the fit algorithm will converge after a few iterations because
the effect of a step in 'm' or 'b' on the deviation of the regression
function from the data is now nearly equal.

not necessary, but also helpful: shift the origin of the regression
function into the x-range defined by the data points (=subtract
10 years from 'x'), this makes the fit algorithm faster.

Thank you, that does solve the problem.  I take it the failure of the
fit to converge properly was a result of some internal problem due
to floating-point limitations?

It seems as though this might be a general issue with plots using
time-valued x data. Might I suggest we do a FAQ entry on this topic?
If you were to post a draft here I would read and try to polish it it
for comprehensibility from a user point of view.

Re: [Gnuplot-info] Help request - linear regression giving screwy results

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

on the x-axis you have seconds since 2000-01-01, so your x-values
are around 315360000.
your y-values are around 20.

this leads to parameters which are different by at least 7 orders of
magnitude.

to bring the parameters into the same range, subtract 10 years and scale the
resulting x-values:

offset=10*365*24*60*60
f(x)=1.e-7*m*(x-offset)+b
m=7.
b=6.
fit f(x) 'comscore.dat' using 1:2 via m,b

[Gnuplot-info] Help request - linear regression giving screwy results

[Eric R. <es...@th...>]

I've been attempting to do trend analysis on U.S. smartphone marketshare.
You can see some of my successful visualizations at 

    http://www.catb.org/esr/comscore/

The problem is that I tried to do a linear-regression fit on Android's
market share and got screwy results.  

To reproduce, save the enclosed comscore.dat and comscore-report, then
do "comscore-report -p Android foo.png" and display foo.png.  What I
see is that the linear-fit line passes through one datapoint but is nowhere
near close to the right slope.  I don't get an error message.

Thanks in advance,

The best way was to do the same coding thing in picture environment in tex -
thats what I found finally..

Re: [Gnuplot-info] The best option to include tikz picture on gnuplot figure

[pban92 <pb...@ya...>]

It worked in your way but I have more complex set-up image to insert. So how
can I do that or is there a general solution how to combine tikz figure in
gnuplot eps figure?

For exapmle, one of the tikz code is as big as the following,


\begin{figure}
\begin{picture}(320,20)(0,12)
\begin{tikzpicture}[scale=0.16]
\pgftransformshift{\pgfpoint{425}{0}}; % shift of (0,0) coordinate 
\filldraw[scale=1,color=black](0,0) circle(7cm);
\foreach \angle in {0,120,240}
\filldraw[scale=1,white,rotate=\angle]

[Gnuplot-info] The best option to include tikz picture on gnuplot figure

1. I am using eps figure (wind tunnel velocity profiles) created by gnuplot.
(Image 123-1)
2. I used tikz package to draw my experimental set-up. (Image 123-2)
3. I am wondering is there a way to include the latex tikz script in gnuplot

Many thanks for any suugestion.

That not necessarily true.  Not universally, either.

Because gnuplot is neither C nor C++, conclusions about those don't 
extend to gnuplot.  Not even incorrect ones.

Re: [Gnuplot-info] power function

[<rhu...@ih...>]

Because pow() is broken in c/c++?

In C and C++ evaluating x*x*x*x*x is faster then pow(x,5).
For Gnuplot this doesn't seem to be the case. Can someone explain why?

Hi all, 
I am new gnuplot user, I am trying to make a 3D surface plot, using gnuplot
4.2 for windows. I have two surfaces and I want to fill  them with different
colors. I have seen  that it can be do  to 2D plot using filledcurves.  Also
I would like to use fill transparent solid options. 

I hope that you can help me,

Re: [Gnuplot-info] php connection

[BBands <bb...@gm...>]

If you have a look at the interface class you'll see that exe() is
used to pass commands directly to gnuplot. For example: $p->exe("splot
x*y\n");

So to plot the sine of x $p->exe("plot sin(x)\n"); should work.

The author is MIA; perhaps you might take up the maintenance of this
interesting project.

Re: [Gnuplot-info] php connection

[e-letter <in...@gm...>]

I am having difficulty to understand the syntax of this file.

The php interface class file was saved as a php file in the web server
directory, i.e. /var/www/html.

A now php file was created, with the command 'include' to reference to
the php interface file in the web server directory.

Part of the interface file states that there is class to activate
gnuplot, but how to test with a simple command?

plot sin(x)

So that the image is created in png format as an image element in an
html file which embeds the php script.

It seems that the function 'plotData' should be used, but how?

Sure. I use gnuplot from visual basic via a simple class I wrote and
from Python via gnuplot.py. Here is a simple php class to get you
started.

http://php-gnuplot.sourceforge.net/

I am happier setting up very simple inter-process communication and
passing command strings directly to gp than using all the helper stuff
so the simplest of interfaces is what I like.

Good luck,

Dear All,

   I am trying to increse width on individual bars in cluster using "set

the LAST bar is labeled as "NAME 3"
