Ben:
Usually you can just use Double.NaN (or Float.NaN) for missing values,
but you say you need this to be "indicated" on the graph. In that case,
you might need/want to make a symbol of some kind? If you're using
Jython, there's an easy-to-use interface for Shapes or text strings that
would allow you to put little symbols at the points...for example:
subs.drawString(display, "X", (9321, 101), color="red", center=1)
would draw a red-colored "X" at time=9321, value=101 (assuming time->x
axis and value->y axis).
