cfchart error

hello all, i did a search on this but found nothing

i am running ubuntu 10.04

railo 3.2.3 final

tomcat

mysql

Anyway, I am trying to figure out if this is a coldfusion vs server type error

I am trying to create a line chart. I try to fill up cfchart series from some items I am pulling from my database. When I do this, the following message is shown: Band count exceeds non-unity number of constants.

When I restrict it to just one single item in the cfchartseries, it still gives the same message. How does one properly use the cfchart?
