Exception with Axis Logbase and Zoom


Recommended Posts


Be have found a condition that will generate a crashing exception in ChartFX.

If you  set

  Chart.AxisY.LogBase = 10

  Chart.Zoom.Mode = ZoomMode.Selection;

  Chart.Zoom.Style = ZoomStyle.Map;

  Chart.Zoom.ViewStyle = ZoomViewStyle.Blur;

and then attempt to use the Map Zoom function when the User selects the area to zoom to, the following exception occurrs with the ChartFX dlls and is not trappable:

'NaN' is not a valid value for property 'Maximum'.

 at System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, OperationType operationType, Boolean isInternal)

at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value)

at System.Windows.Controls.Primitives.RangeBase.set_Maximum(Double value)

at ChartFX.WPF.Axis.f()

at ChartFX.WPF.Axis.b(ScaleInfoBase A_0, Double A_1)

at ChartFX.WPF.Axis.a(ScaleInfoBase A_0, Double A_1, Boolean A_2)

at ChartFX.WPF.Axis.a(ScaleInfoBase A_0, Double A_1, Boolean A_2, Boolean A_3, Boolean A_4, Double A_5)

at ChartFX.WPF.Axis.b(ScaleInfoBase A_0, Double A_1, Boolean A_2, Boolean A_3, Boolean A_4, Double A_5)
