Hello all, I am having some difficulty creating a custom Chart renderer for a Column Chart, and I was hoping someone could point me in the right direction.

 

What I’m trying to accomplish:  Column chart where if a value being charted is less than 0, than display the column in red, else in blue.

 

What I’ve tried:  In AS, created a class which extends the SimpleBoxRenderer class and well, my first stab, which I cant attempt, is to override the beginDraw method, and inspect which value in there is the actual value being charted.  From there, I can set the Stroke color.  I’m not sure if this will work or not, but if its not this method, than it’s the draw method. 

 

 

However, the problem arises when I try to subclass that class itself.  When I try to create the class, I try to import that parent (mx.charts.renderers.SimpleBoxRenderer), but it cannot find it.  FlexBuilder defines every other package, except for that one, so I’m wondering if there is some kind of configuration issue at hand.  It seems that every package I check for is there, except for that one.  Any suggestions?

 

Thanks for your time and consideration

 

Nick
