When you use axis paging or data zooming the chart contains more data than the user can actually see. In some cases you may want to print the whole chart contents. To achieve this you may take advantage of the PrintDocumentController property of the NPrintManager object allowing you to change the default controller (NSinglePageDocumentController):

NPrintManager printManager = new NPrintManager(chartControl.Document);
printManager.PrintDocumentController = new NAxisPagingDocumentController();

Dim printManager As New NPrintManager(chartControl.Document)
printManager.PrintDocumentController = New NAxisPagingDocumentController()

Now if the chart has an axis in paging mode the control will generate as many pages as need to display the whole axis range page by page.
