easiest way to plot x,y graphically during run-time?

[esmail bonakdarian]

Hi Brian,

Thanks for the code sample, that looks quite promising. I can
run it and understand most of it - my knowledge of pylab/matplotlib is
still quite rudimentary. I wish there was a good manual/tutorial that
could be printed off (or for that matter a book) on this as it seems
quite cabable and feature rich.

here is a sample.  again, direct questions to the matplotlib list for
possible better ideas.


from pylab import *

# initial positions
x0=rand(5)
y0=rand(5)

ion()  # interactive on

for t in linspace(0,10,100):
    
    x=x0+0.1*cos(t)
    y=y0+0.1*sin(t)
    
    if t==0:  # first time calling
        h=plot(x,y,'o')
    else:
        h[0].set_data(x,y)

    draw()
