XY Chart Labels Centering on Bar

Is there some trick to getting the labels on an XY chart to center under the bars?

I have data that is available every 30 minutes. When I present it with timeUnit=Minute, count=30 it does show up, but the labels are not under the bar.

If I change to timeUnit=Hour, count=1 it properly centers how I want to see it but I no longer have my half hour columns:



there should be an answer in this topic for you^^
