I'm getting an unhandled exception from the xamDataChart, it's pretty random but it seems to happen most often when I switch the data series that the chart is to display.  Basically when the operator requests to see a different set of values, I clear the chart series and recreate a new set of series to display.  This is the info I am getting from the exception.  Looking at the inner exception it looks like the chart is trying to set the height of something to infinity?
