Massimo:  I've no idea what a "sky plot" is. Can you point us to an example?

Hi Jef,

please apologize me for the delay
i had days without internet connection :-/

sorry if i gived you a bad explanation ...
for sky plot i means plot like :

http://www.tpub.com/content/armyengineer/en0593a/en0593a0209.htm

the data i'm receiving from the gps device are :

PRN = satellite ID
EL = ELevation (integer 0-90)
AZ = Azimuth (integer 0-359)
Ss = Signal-Strenghts (decibels)
Used = (1,0)


for each satellite visible at the moment,
i receive data for each second.

i'm printing the data in an html table

but i tring to learn how to use matplotlib to display the data in a  
"sky-plot" (i don't know the real name of this polar-diagram)

i gived a look at matplotlib tutorial pages .. and i find really  
usefull the "web-plot" example
  ... i'll follow that way
but the real problem is :

  i don't know the math formulae and matplotlib syntax needed to  
create a such kind of plot.

thanks for any suggestion!

regards,

Massimo.
