Using TChart.Draw() with teechart.pocket

Hi, I'm trying to use TChart.Draw() with TeeChart.Pocket with I think the latest version of TeeChart .NET 2009, but seem to only be able to use the Draw(graphics) overload. The reason I wish to use Draw(void) is that I want to avoid drawing the chart to screen twice each time I update it. I am using...
