I am trying to export a sfchart via the example in the knowledge base but I am getting the error "The parameter value must be greater than zero." What is causing this error and how can i fix it? See picture below.

Thanks for the reply but I am trying to do it in the code behind rather than in xaml. I don't understand where pixelWidth is not being set and how to fix it.

Hi Caleb, 
Thanks for the update.  
We have analyzed the reported problem based on the exception stack trace and we suspect that you are trying to save the chart even it is not in UI. If it so, you need to call Measure() and arrange() methods of chart manually before saving it.  
  
We have prepared a sample based on this and it can be downloaded from the below link, 
 
Sample:Save-SfChart
 
  
If your requirement is different from our solution then we request you to provide some more detail about your exact requirment. It would be more helpful for us to provide a solution as sooner.

I have implemented this solution and can save a chart but chart.Arrange takes a very long time. Is there any way to speed up the sizing? It takes almost 30 seconds to size the chart.
