Following the custom series example: http://help.infragistics.com/Help/NetAdvantage/WPF/2012.2/CLR4.0/html/xamDataChart_Creating_Custom_Series.html
The GetItem tooltip example does not work when the chart is zoomed in. You can also see this behaviour in the Samples Browser. If you zoom in with the scroll wheel on the custom series the ToolTips are either misplaced or don't show at all. What would I have to do with my custom series to solve this issue?
OK, to properly get the cursor point when the chart is zoomed in, the line in the tutorial should be...
Point cursorPoint = new Point( (worldPoint.X - this.SeriesViewer.ActualWindowRect.Left) * this.Viewport.Width / this.SeriesViewer.ActualWindowRect.Width, (worldPoint.Y - this.SeriesViewer.ActualWindowRect.Top) * this.Viewport.Height / this.SeriesViewer.ActualWindowRect.Height);
instead of...
Point cursorPoint = new Point( this.SeriesViewer.ViewportRect.Width * worldPoint.X, this.SeriesViewer.ViewportRect.Height * worldPoint.Y);
