I have a requirement to include some images from our XamDataCharts(scatter and column) into seperate RTF reporting part of the application. The problem is that the placeholders for the charts are different sizes than the chart visualization page. I tried a couple of different things to resize the images but nothing looked right.  I tried to clone the control using XamlWriter.Save() but it just hung.  So I decided to create an in memory copy of the control, bind it up, set it to the desired size, and then call rendertargetbitmap to grab the image.  This worked great for the 'generic' controls on the page but the xamdatachart resized but would not show the actual chart data.

        public BitmapSource GetBar()
        {
            var vm = DataContext as MyChartViewModel;
            var are = new AutoResetEvent(false);
            var lc = new myBarChart { DataContext = vm };
            lc.Data = vm.BarChartData;
            lc.BarChartSource = vm.SelectectedBarChartDisplayMode.SourceType;
            lc.Width = 350;
            lc.Height = 400;
            lc.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Loaded,
                                 new Action(() => { are.Set(); }));
 
            are.WaitOne(2500);
            lc.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
            lc.Arrange(new Rect(lc.DesiredSize));
            return lc.Export();//calls rendertargetbitmap
        }
