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.
Esmail --- 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() bb -- Brian Blais bbl...@bryant.edu http://web.bryant.edu/~bblais _________________________________________________________________ Windows Live™ SkyDrive™: Get 25 GB of free online storage. http://windowslive.com/online/skydrive?ocid=TXT_TAGLM_WL_SD_25GB_062009 -- http://mail.python.org/mailman/listinfo/python-list
