MMCCPaulEden Posted June 29, 2010 Report Share Posted June 29, 2010 Hi If the Map zoom style is enabled in conjunction with a radar, pie and possibly other such single series chart types, when the User selects the zoom area, the following exception is generated by the ChartFX dlls that is not trappable. "Object reference not set to an instance of an object." at ChartFX.WPF.ZoomArea.a(IPlotArea A_0, Point A_1, Point A_2, ZoomStyle A_3) at ChartFX.WPF.ZoomArea.b(Object A_0, MouseButtonEventArgs A_1) at System.Windows.Input.MouseButtonEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget) Quote Link to comment Share on other sites More sharing options...
JuanC Posted June 29, 2010 Report Share Posted June 29, 2010 Unfortunately Zoom Map, Style and Scroll depend on manipulating the X and/or Y axes to handle zooming while retaining visibility of other items in the chart such as axis labels, titles, legend, etc. Radar, Pie, Doughnut and other "non-axes" charts do not support these types of zoom, in these cases we would recommend you use the Zoom Magnifier feature. We have fixed the exception thrown when the user selects the zoom area and this fix wil be available in our next hotfix which should be available in a day or two.

JuanC Posted June 30, 2010 Report Share Posted June 30, 2010 Build 3833 should fix the zoom exception issue on not supported galleries (Pie, Doughnut, Radar, etc.) JuanC Quote Link to comment Share on other sites More sharing options...
