// <start_hue>
//      Starting hue (0..1) for graph
// <hue_change>
//      Delta hue for graph (+ or -)
// <grow_time>
//      Time to grow graph, back to front
// <hold_time>
//      Time to hold completed graph
// <two_dim/>
//      If present, draw 2-D graph
// <graph_alpha>
//      transparency of graph (0..1)
