Detailed Description

Draws one or more line graphs.

After settings bounds, use setLineCount(int) to set how many lines are used. You can then fill in the data using addValues(float*) by passing an array of values for each line in the graph. When the end is reached, the graph is cleared automatically for a continuous graph.
