How Do I Fix Wpf Toolkit Chart Axes Error When Leave Datattmplate For Another In Same Window

I am currently using the toolkit chart to display a column chart within a data template in a resource dictionary. The chart display accurately and quickly when loaded. However when the view in the window is switched to a new data template through content control data trigger bound to VM) in dictionary I get an error stating that the axes could not be determined maybe due to not setting the orientation.

XAML

<DVC:Chart.Axes>

   <DVC:Chart.LinearAxis Orientation="Y" Interval="1" Minimum="0"

etc.

If I comment out the Axes XAML I have absolutely no problem but the chart looks terrible as it goes with all default design and setting. Apologize for not posting full code but this is a work project and cannot. All data is built with Key value pair bindings.

Tanks for any help
