[Shows the Text property of the Point object.]

I'm trying to put a custom text on the PointLabels in a pyramid graph but the only way that i have seen is with:

chart1.getAllSeries().getPointLabels().setFormat("%L%");

But i don't know how to change the "text property of the point object"

 

Someone can help me? Someone know other way to change this text?

 

Thanks in advance
