java.lang.Object

org.usfirst.frc.team1736.lib.WebServer.CasseroleWebPlots

public class CasseroleWebPlots
extends java.lang.Object

DESCRIPTION:
Realtime Plot View webpage definition class. Allows the user to send a set of variables to an interface where they can be plotted in real-time.
ASSUMPTIONS:
Be sure the casserole webserver is started at some point, otherwise the webpage won't be displayed. Note that states can only be added (even at runtime), but never removed. At least not yet...
USAGE:

1. On init, call addNewSignal with all the signals you want available.
2. During runtime, call the addSample() method to record a new value to be plotted.
