im using the annotated timeline to display server performance, (page  
load speed vs time).  each time a page in my app loads, it stores a  
timestamp and a value for the time required to load the page.

this data is used in the annotated timeline data set like this:

data.setValue(0, 0,  new Date(2008, 10, 17, 13, 17, 36) );
data.setValue(0, 1, 0.665919065475);
data.setValue(1, 0,  new Date(2008, 10, 17, 13, 17, 41) );
data.setValue(1, 1, 0.0146939754486);
data.setValue(2, 0,  new Date(2008, 10, 17, 13, 17, 45) );
data.setValue(2, 1, 0.391777992249);

the problem with this is that from point to point there is a line, I  
need the lines to go back to zero after every point or else I end up  
with a graph that looks like this (notice the slanted lines between  
points, i want the line to immediately drop back to the baseline):

is there a configuration option which will automatically drop the  
values back to the baseline after each date or do i need to add a 0  
value after each point myself?
