[Matplotlib-users] Dynamic plotting?
Hi list I've been asked to transform my app to something more dynamic it currently reads an xml file, it has now to read a stream of xml from a socket (I can handle this part :D) and plot each point as they are coming from the network. I'll end up having tons of points over multiple axes; I guess doing sonething like fig.plot(concat(old-data,new-point)) would be rather inefficient and I wonder if someone ever made something like this using matplotlib? or any hints on where to start from? thanks :) This message contains confidential information and may contain information that is legally privileged.

You can refer to animation examples [1] for code that does what you want. [1] http://matplotlib.sourceforge.net/examples/animation/index.html at the very end, you update the line data with set_ydata() , set_xdata() or set_data() and then call a draw() on the figure.

oh, I knew about set_{x,y,}data() but I actually though I had to feed it
the whole dataset each time.
It's clear enough in the examples :)
maybe the doc should be a bit more verbose?

thanks.
