Real time plot

[Jean-Francois Canac]

I am reading a large amount of data from a COM port (or from a file) at a
rate of 20 records per second. It is about positioning of a vehicle on a
race track. 

In each record we have time, position (lat and long) speed, course all from
GPS equipment. I would like to Produce a graph in real time with these
records to see the  vehicle moving on the track. The goal is to study the
vehicle performance and to always have its position, the application would
run around 24 hours.

 

I would like to write the application in Python and I am wondering which
plot interface would be the more appropriate, I have seen matplotlib, but I
do not know how to make real time applications with big amount of data. Is
hippodraw more suited to this use or an other interface?

Many thanks
