My application uses RadDocking. When the WPF Report Viewer is hosted in RadDocking, some Graph labels appear cut.
The problem is related to the property UseLayoutRounding="True" in the RadDocking.
The workaround is to use the following setting:
RadPane pane = new RadDocumentPane();
pane.UseLayoutRounding = false;
pane.Header = "Report";
pane.Content = reportViewer;
DocumentPaneGroup.AddItem(pane, Telerik.Windows.Controls.Docking.DockPosition.Center);
