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 On Tue, May 18, 2010 at 4:27 PM, Sandy Ydnas <cd...@li...> wrote: ok but first I should download liveplots all files one by one or package? but way in http://code.google.com/p/liveplots/downloads/list there are no files to download Sandy From: fcc...@gm...

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.

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