WPF Charting toolkit: How to center data point

Hi, 

I have 3 charts that load at any given time 1 minute of data points from a database,  E.g  BETWEEN  Date time 23-07-2013 22:01:02  23-07-2013 22:02:02.  The chart then loads the data starting at point  23-07-2013 22:01:02. I would like the charts to center the starting date, rather than having it to the full left.

I'll try to add some screen shots later on today.

Thanks

Jamil
