Hello,
I'm new in matplotlib, but I have became a fat!
First of all, I have to apologize for my bad English, I hope you can
understand what I mean.
Making some programs I have found the same problem:
> -What I want? I want to plot two sets of changing data using the same
> windows.
> -The problem? My code is:
> -----------------------
> x,y = evol.plot_init()
> pylab.ion()
> pylab.subplot(211)
> line,=pylab.plot(x[0],x[1])
> pylab.draw()
> pylab.ylabel('Posiciones')
> for k in pylab.arange(Nt):
> x, y = evol.plot_step()
> line.set_ydata(x[1])
> pylab.draw()
>
>
> pylab.subplot(212)
> line,=pylab.plot(y[0],y[1])
> pylab.draw()
> pylab.ylabel('Momentos')
>
> for k in pylab.arange(Nt):
> x, y = evol.plot_step()
> line.set_ydata(y[1])
> pylab.draw()
> ---------------------------------------------------------------------
> And if you run this, one draw and anim is done first, you have to wait
> it to stop, and then you can see the other want.
> The thing is that I want that the two anim figures runs at the same time.
>
> Any idea?

Hello darkside,
I set up a little program hoping it offers a solution to your problem.
