Refresh interval matplotlib

[rankinstudio]

I have rsudp running on a PC. It works great but using matplotlib is very cpu intensive. It would be nice to have a refresh interval in the settings file for the plot so it didn't refresh as fast as it possibly can. I'd be fine with a 5s refresh if it didn't hit the cpu as hard.

Hi @rankinstudio, I think this should be fairly simple to implement, but I don't have time to fix it at the moment. The work required would be:

• [ ] add a refresh interval parameter in the settings file (refresh_sec or something similar perhaps)
• [ ] add a way to load this parameter in client.py and send it to the Plot class
• [ ] add a variable to keep track of this interval in Plot initialization
• [ ] use this variable to calculate the number of skipped refreshes (currently based, I think, on the number of received data packets versus the packet transmission rate)

I can take a look at it.
