Hi,
I want to design a bubble chart as the image attached below in Birt v2.5. So I wanted to know, how easy it is to draw reference lines in the bubble chart? Also, is it easy to create quadrants with the bubble charts?
I also wanted to know whether we can add more than one legend item in the bubble chart. To my knowledge, there isn't a way to add a legend item. Is there any workaround for this?
Any comments/suggestions/inputs would be of great help.

Regards,
Aarti
