How to print child chart for TeeChart.WPF

[Candy]

I create more child chart in tChart1, but how to print child chart, please look at the code:

// init child chart
for (int i = 0; i < 4; i++) {
Steema.TeeChart.WPF.TChart child = new Steema.TeeChart.WPF.TChart();
...
...
tChart1.Children.Add(child);
}

// Referring to the teechart wpf example
documentViewer1.Document = CreateFixedDocumentWithPage();

// Referring to the teechart wpf example
FixedDocument CreateFixedDocument() { ... }
...

private PageContent CreateFirstPageContent() {
PageContent pageContent = new PageContent();
FixedPage fixedPage = new FixedPage();
Canvas canvas1 = new Canvas();

...
Steema.TeeChart.WPF.TChart child = (Steema.TeeChart.WPF.TChart)tChart1.Children[0];
DrawingVisual d = new DrawingVisual();
DrawingContext g = d.RenderOpen();
child.Draw(g);
AdornerLayer parent = AdornerLayer.GetAdornerLayer(child);
if (parent != null)
{
Adorner[] adorners = parent.GetAdorners(child);
if (adorners != null)
{
foreach (TeeAdorner item in adorners)
{
item.Draw(g);
}
}
}
g.Close();
...

fixedPage.Children.Add(canvas1);

....
}

Hi Candy,

You should do something very similar to the demo. Find attached a simple example project showing it. This is a Visual Studio 2013 .NET Framework 4.5.1 project. You just need to change the project TeeChart.WPF.dll reference to the version you use. If you have any problem with the project just use MainWindow.xaml and MainWindow.xaml.cs.
