Detailed Description
Class to draw line graph of recent values of a topic's selected field on the display. The bounds of the graph are dynamically updated to fit the recently recieved data. THis means that when a new value is recieved that is larger than the bounds the graphical range will be expanded. After a while the graph shrinks the range to fit the mose recent data recieved.
