Chart Dates Format Problem

My data set has monthly records with the date defined as a character with format '2007-02'. These values display correctly in graphs in my ColdFusion MX application when my local computer is acting as the host. However, when I move my application to our external host, the dates change to format {ts '2007-02-01 00:00:00'}. This change makes the graph hard to read. I'm at a loss as to where I should be looking to fix this problem. Can anyone help?

Thanks in advance.
