Using a DateAxis with A XYBarRenderer

[MattBallard]

Is there a way to align the tick marks in the middle of the Bars?

I have a DateAxis as my DomainAxis for my XYPlot and need to align certain days with bars from my XYBarRenderer. The Bars are vertical. I am using the setTickMarkPosition method and it is not changing anything.


Here is my code:
