I am receiving a data stream from BPL Pulse Oximeter, and I am storing those data on a list, I want to create a line graph with the data from the list, Does anyone have any idea?

Staying in Ai2, use a canvas and draw line, you will need to convert each value to x,y coordinates of the canvas

A bit of work to do in the background creating the axes etc

Otherwise look in the FAQ for charting opportunities
