Column Chart with Item Renderer

When doing the Column Chart with fillFunction for a question in the Flex Forum, the poster said that he was trying to do something a little different.

Finally, after looking at the Stacking Columns example and the Multiple Axis Example, reconstructed the chart using the static objects instead of dynamically creating the chart. From there, I recreated the chart items in a function and determined that the first issue the poster was having was building Continue reading Stacked Column Chart with Line Series
