I have a XamDataChart that has both a Numeric X axis and a Category X axis. I am never using both at the same time. Looking at the picture above though you can see that the XamDataChart has been pushed up from the bottom. I have tried using both the 'Visibility' & 'IsEnabled' properties of the Category X & Numeric X axes to fix this with no luck. Is there a better way to resolve this other than creating the axes in codebehind? Just to clarify what I mean each chart object will have one of two cases: Case1 - Numeric X & Y, Case2 - Numeric Y & Category X.

 <ig:CategoryXAxis x:Name="CategoryXAxis"
                                      Stroke="Black"
                                      StrokeThickness="3"
                                      MinorStroke="#00000000"
                                      MinorStrokeThickness="1"
                                      ItemsSource="{Binding CategoryLabels}"
                                      Label="{}{XLabel}"/>

  <ig:NumericXAxis x:Name="xAxis"
                                         Stroke="Black"
                                         StrokeThickness="3"
                                         MinimumValue="{Binding Xmin}"
                                         MaximumValue="{Binding Xmax}"                                                                                                                     
                                         Interval="{Binding XMajorInterval}"
                                         MinorStroke="#00000000"                            
                                         MinorStrokeThickness="1"/>
