I thought the OP's original question was something like the Matlab plot editor (or whatever is its name), which allows you to edit line colours, styles, gridlines styles, this kind of stuff on a live plot (mind you, it's been 6 years since I used Matlab for the last time and I may have forgotten what the plot editor does).

There is one non-trivial difference between Matplotlib and Matlab.
Matplotlib is just a library, and not an integrated package with its
own event processing loop, multithreading, etc. When you plot()
something under Matlab or Scilab, you generate some objecs (gcf, gca)
and other stuff, accessible from outside. Your program turns normally,
your console works. So, you may launch a procedure which analyses all
the plotted data and change the patches, lines, collections, etc.,
using the matplotlib jargon.
In matplotlib, upon show(), you relinquish the control. The interaction
becomes clumsy, the animation becomes clumsy, since matplotlib doesn't
give you the full access to the event loop.
OF COURSE you may do it, but it will require some work.
One possibility is to use an interface which by design works (I
presume...) in a separate, non-blocking thread. I mean: IPython. If you
launch IPython --pylab, then you may, e.g. construct:
x=linspace(0.0,25.0,300); y=sin(x)
plot(x,y)
and the figure is created without show().
Then, write:
a=gca(); p=a.lines[0]
and nothing more difficult than:
p.set_lw(3); p.set_color('red'); draw()
You have edited your line. No need to change the code of matplotlib.
Good luck.

Just to be clear, you are speaking of the difference between interactive
and non-interactive modes, which is entirely switchable in matplotlib.
However, widgets can be used in either mode. mpl can do what matlab can
do, and more -- in theory. We simply do not have all the widgets and tools
made.
Ipython uses mpl with interactive mode turned on. All artists are available
for editing at any time *until* the figure is destroyed (in either mode).
It just happens that the execution moves past show() in non-interactive
mode only when the figures are destroyed.
As for any clumsiness for animations, it is because the feature is still
new and Ryan May and I would greatly welcome additional viewpoints in the
design discussions.

For the wx backend to matplotlib, wxmplot (http://github.com/newville/wxmplot, http://newville.github.com/wxmplot/) does provide some of the basic editing features for simple 2d line plots such as changing colour, style, markers, text labels and so on via a GUI form, much as you describe. For image displays, it allows changing the colour table, smoothing, and rotating and so on. It is definitely not as complete as all of matplotlib, and I'm sure it could be improved. Still, it can serve many simple plotting needs where one wants to give the end-user the ability to customize the plots, and wx/matplotlib developers needing might find it useful. --Matt Newville -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
