GraphXLo - Graph your XLoBorg from Python

So you have just gotten your hands on an XLoBorg, but you want to know what sort of data you can expect to see when using it, how can you tell?
Maybe a picture of what the data looks like would help.

GraphXLo takes the data from an XLoBorg and draws it on the screen using a Python plotting library, matplotlib.
There are some options to configure from lines 5 to 19:

• interval is the number of seconds the script waits between updates, smaller numbers will produce a better graph but consume more processing power
• plot...Colour are the colours used for each plot, configure to taste :)
• plot... are boolean (True or False) flags telling the script which lines to plot

Here's the code, you can download the GraphXLo script file as text here
Save the text file on your pi as GraphXLo.py, in the ~/xloborg directory
Make the script executable using
chmod +x ~/xloborg/GraphXLo.py
then install matplotlib using
sudo apt-get -y install python-matplotlib
and run using
~/xloborg/GraphXLo.py
