You shouldn't make the elements of the datalar array into strings; leave
them as Python objects:

datalar = []
for ii in range(n):
    datalar.append(
        Gnuplot.Data(x, ozfonksiyon(omegalar[ii],x), with_='lines')
        )
gp.plot(*datalar)

[Gnuplot-py-users] Plot list of PlotItems

[Cuneyt E. <cun...@gm...>]

Hi,

I wan to plot more than one curve in the same graph using same function with
different parameters. The following code works without problem.

from numpy import *
import Gnuplot

gp = Gnuplot.Gnuplot(persist=1)
x = arange(0,1,0.01,dtype='float_')
d1 = Gnuplot.Data(x, ozfonksiyon(omegalar[0],x), title='1. ozdeger',
with_='lines')
d2 = Gnuplot.Data(x, ozfonksiyon(omegalar[1],x), title='2. ozdeger',
with_='lines')
d3 = Gnuplot.Data(x, ozfonksiyon(omegalar[2],x), title='3. ozdeger',
with_='lines')
d4 = Gnuplot.Data(x, ozfonksiyon(omegalar[3],x), title='4. ozdeger',
with_='lines')
d5 = Gnuplot.Data(x, ozfonksiyon(omegalar[4],x), title='5. ozdeger',
with_='lines')
gp.plot(d1,d2,d3,d4,d5)

in this code ozfonksiyon and omegalar are user defined functions. But what I
want is to create plotitems (d1,d2,d3,d4,d5) in a for loop. I modified the
code like below,

for ii in range(n):
    datalar.append("Gnuplot.Data(x, ozfonksiyon(omegalar["+str(ii)+"],x),
with_='lines')")
gp.plot(*datalar)

I get this error.

/usr/bin/python -u  "/media/disk/doktora_tezi/tek_cubuk/python_files/CALISAN
KOD/fix_free_controlled_parametrelerin_degisimi_deneme.py"

gnuplot> plot Gnuplot.Data(x, ozfonksiyon(omegalar[0],x), with_='lines') ,
Gnuplot.Data(x, ozfonksiyon(omegalar[1],x), with_='lines') , Gnuplot.Data(x,
ozfonksiyon(omegalar[2],x), with_='lines') , Gnuplot.Data(x,
ozfonksiyon(omegalar[3],x), with_='lines') , Gnuplot.Data(x,
ozfonksiyon(omegalar[4],x), with_='lines')

         line 0: ':' expected

What am I doing wrong?

You need to remove the NaN before plotting. This is also the behavior  
I would want, not that things are plotted with undefined values  
without me knowing it.

To obtain only the nonNan from a x,y plot:
z = N.asarray([[x,y] for x,y in zip(a,b) if not math.isnan(x) ])
then plot z[:,0] and z[:,1] instead of x,y

Probably there are nicer ways to do this filtering, a masked array perhaps.

[Gnuplot-py-users] Handling NaN-values

[Felix S. <fel...@ui...>]

Hi there,

i got a question on how to best handle NaN values.

I'm plotting 3 x-y curves into one plot (data comes from 3 files which 
are read and processed earlier in my code).
Sometimes one of them has NaN-values at the y=0 point. If i just convert 
the NaN-values as everthing else:

data_array.append(float(THENANVALUE))

the data array contains the nan and my values just fine. However if i 
then proceed to g.plot(...), i get a

line 0: Bad data on line 1

error.

What i would like to have, is a plot where the undefined lowest value is 
ignored and plotting starts at the first defined value.

Is there a simple solution to this/ any suggestion?

Thanks in advance for any answers! :-)

Felix

Possibly OFF TOPIC.

I'd use Matplotlib for this.

[Gnuplot-py-users] Outputting animated graph from Python

[Colin R. <col...@gm...>]

Hi,

I have a program that generates a list of tuples (x,y) pairs that I am
plotting to visualize with Gnuplot.

for example: g.plot[(x1,y1),(x2,y2),(x3,y3),.......,(xn,yn)]

The program works fine and displays correctly, but I would prefer to have
the graph animated, for example to view the graph plot in real time form
point 1 to point n.

I tried studying the animated examples in GNUplot demos but didn't get very
far...

Any suggestions?

Thanks for your time!

Currently, Gnuplot.py does not even read the output of gnuplot, let
alone try to understand errors that it writes to its output.  Presumably
one would have to open a two-way connection to gnuplot then listen for
such messages on the gnuplot process's stdout and/or stderr, and it
would probably require a little bit of intelligence to distinguish error
messages from simple informational messages.

If this were implemented it would open the way to doing a couple of
other useful things, like reading the output from gnuplot "fit" commands.

FWIW, I think PyGTK is a better choice than tkinter, as it is more
modern, has more features, and looks much better.  Most people probably
install using a package manager, in which case installing PyGTK should
be an insignificant amount of work.

Well, I don't know if using Tkinter would give me a larger audience
maybe you're right. I'm not an experimented programmer, I do that in my
free time. I have chosen PyGTK because I have already used GTK+.

I have already written the program but I only cannot catch errors given
by Gnuplot when user enters an invalid function.

[Gnuplot-py-users] Catch Gnuplot errors

[Milan S. <mil...@gm...>]

Hello,

I'm student and I use often Gnuplot to plot data and different
functions. That's why I decided to write a front-end with Python &
PyGTK.

The gnuplot.py module is very useful but reading the
documentation, I didn't find how to catch errors given by gnuplot (for
example: "undefined variable t"). 

Does someone know how to do that?

Thanks :)

Re: [Gnuplot-py-users] install issues

[Yann T. <yan...@bu...>]

I figured things out: I was not correctly setting my PYTHONPATH environment
variable.

__init__.py in the Gnuplot directory makes the directory a package, so that

import Gnuplot

works as it should. Correct me if I'm wrong.

Thanks,

Yann <gnu...@li...>

[Gnuplot-py-users] install issues

[Yann T. <yan...@bu...>]

Hopefully there is an obvious answer to this question: Am I supposed to copy
some file to create Gnuplot.py?

I'm installing to a non-default location, so I run

python setup.py install --prefix /my/location

Everything works great without issue, or so it seems. But I don't get a
Gnuplot.py file. It doesn't come in the 1.8 tar.gz file and it's not in the
repository, so I thought setup.py would create this file.

Sorry if I've overlooked something strait forward in README.txt.

I'm running on a Linux machine and
Python 2.4.3
gnuplot 4.2 patchlevel 4
numpy 1.3.0

Thanks,

Yann

Re: [Gnuplot-py-users] is it possible to continue to Debug when figure is created??

[Fabi R. <fa...@ai...>]

Hi,

You can use multiplot instead of replot...this allows you more freedom and
will skip you from the annoying limited number of threads. Example;


Graph=Gnuplot.Gnuplot(debug=1,persits=1)
Graph('set multiplot')

Graph.plot ( data 1, data2... (anything you want to plot))

If you plot several graphs at the same time, like using a loop,

for i in irange:
   Graph.plot(data[i])

Graph('set nomultiplot')



These 'set multiplot' and 'set nomultiplot' are
really essential.

Cheers

I use Linux, but I'll give it a try:

on a command prompt go to the liveplots source diretory, the one with setup.py in it and type 

c:\python2.6.exe setup.py install

 on the line above use the actual path of your python executable. That line  should install liveplots, assuming you have all the pre-requisites: (numpy, gnuplot, etc...) and an internet connection so that it can download extra dependencies.


However, it strikes me that since you don't know much about Python, Liveplots will not be of immediate use to you since it is supposed to be called from within Python programs.

good luck,

Flávio

You are supposed to use mercurial to checkout the source code tree...

Hi Sandy,

You error is due to the fact that you have not imported Gnuplot as you should. So that snippet would become:

import Gnuplot
Gnuplot.GnuplotOpts.prefer_inline_data = 1

Gnuplot.GnuplotOpts.prefer_fifo_data = 0

Liveplots is free-software and you are welcome to use it if you find it suits your needs. To install it, if you have setuptools installed, you write:

easy_install liveplots

otherwise, just checkout the code, as explained here https://code.google.com/p/liveplots/source/checkout, and run:

python setup.py install

these commands may be sligthly different depending on which operating system you use.

Sandy,

Like Michael said, You can turn off fifo data transfer and use inline with these lines:

Gnuplot.GnuplotOpts.prefer_inline_data = 1
Gnuplot.GnuplotOpts.prefer_fifo_data = 0

I do this in Liveplots[1] and found that inlining data improved the performance enormously. Besides, since I use Python's multiprocessing module to plot data from children processes, FIFO did not work for me.

I personally don't use pdb, but I don't know of any reason why it should
be difficult to debug code that uses Gnuplot.py.  The only thing that
occurs to me is that the use of FIFOs to communicate data to gnuplot
currently requires the use of additional threads that write the data to
the FIFO, and debugging multithreaded code might be tricky.  But the use
of FIFOs is optional; you could configure Gnuplot.py to use temporary
files or inline data instead.

Please tell us what you find out!


Use
g  = Gnuplot.Gnuplot(persist=0) 
The persist=0 should allow you to easily jump over the code that does the figure.

Benny

In the Liveplots source package theres a file called simple.py with a few

Re: [Gnuplot-py-users] is it possible to continue to Debug when figure is created??

[Flavio C. <fcc...@gm...>]

I am open for discussing how the functionality I have in Liveplots could be
moved upstream into gnuplot.py. It would definitely be useful to have more
eyes looking at my code and helping to identify bugs. I believe the first
step will be for someone familiar with Gnuplot.py code to have a Look at the
liveplots source (it's tiny) and determine what would be useful to
"transplant"

You are supposed to use mercurial to checkout the source code tree...

to make things easier, I have just added an archive with the source  in the featured downloads.
http://code.google.com/p/liveplots/downloads/detail?name=liveplots-0.3.tar.gz

cheers,

Flávio

Hi Sandy,

You error is due to the fact that you have not imported Gnuplot as you should. So that snippet would become:

import Gnuplot
Gnuplot.GnuplotOpts.prefer_inline_data = 1

Gnuplot.GnuplotOpts.prefer_fifo_data = 0

Liveplots is free-software and you are welcome to use it if you find it suits your needs. To install it, if you have setuptools installed, you write:

easy_install liveplots

otherwise, just checkout the code, as explained here https://code.google.com/p/liveplots/source/checkout, and run:

python setup.py install

these commands may be sligthly different depending on which operating system you use.

Hi Flávio
thank you very much for help
 
if we use 
 
from numpy import * 

g  = Gnuplot.Gnuplot(persist=0) 
 
then
NameError: name 'Gnuplot' is not defined
File "C:\start_Feb_8\my_PY_code\May_18__gnuplot_answer_test_1.py", line 3, in <module> 

  g  = Gnuplot.Gnuplot(persist=0)
as I mentioned I am very new in Python
may I use you project [1]http://code.google.com/p/liveplots/

but how to install it??
 
Thank you very much in advance

Sandy,

Like Michael said, You can turn off fifo data transfer and use inline with these lines:

Gnuplot.GnuplotOpts.prefer_inline_data = 1
Gnuplot.GnuplotOpts.prefer_fifo_data = 0

I do this in Liveplots[1] and found that inlining data improved the performance enormously. Besides, since I use Python's multiprocessing module to plot data from children processes, FIFO did not work for me.

I personally don't use pdb, but I don't know of any reason why it should
be difficult to debug code that uses Gnuplot.py.  The only thing that
occurs to me is that the use of FIFOs to communicate data to gnuplot
currently requires the use of additional threads that write the data to
the FIFO, and debugging multithreaded code might be tricky.  But the use
of FIFOs is optional; you could configure Gnuplot.py to use temporary
files or inline data instead.

Please tell us what you find out!


Use
g  = Gnuplot.Gnuplot(persist=0) 
The persist=0 should allow you to easily jump over the code that does the figure.

Benny

Hi Allan,

I am the author of Liveplots and it is quite an specific project, which happens to use Gnuplot.py as many other projects do. I don' see what benefit would come from joining the two. Though naturally, being open-source projects, they are free to share code as needed, so that there are no unnecessary duplication of development effort.


First, I have not looked at the liveplots code, only the blog posting.

I think there are probably many users of gnuplot.py that do the drawing in a separate process, so as not to hold up the numerics (waiting for data to be written, ...). Moving such a construct, with a queue system, inside of Gnuplot would be benificial, so that users can have a basic version of that without needing to bother about processes.

Benny




cheers,

Flávio

Might making this part of Gnuplot.py be appropriate?
