[flexcoders] Setting the label attribute in the PlotSeries object to an array?

[tedgies]

Hi,

Is there a way to put additional information in the Label in charts?
If you look at the example below, i have a one dimensional array 
with 2 book titles in it.  I am plotting the timesPurchased in the Y 
axis.  On the x axis i just have a unique index of each book.  What 
i would like to do is make the label attribute of the PlotSeries 
access the additional data in the array.  So, if a user moused over 
the 139 point in the plot, they may see the book title, and even the 
publisher.
