無法正確拖動VertisStackedAxes中的AxismarkerAnnotation

Question

我使用SciChart組件的VerticallStackedAxes並將7 AxisMarkerAnnotation添加到每個NumericAxis，但AxisMarkerAnnotations除第一個以外不可拖動。

這是我的用戶代碼的一部分：

<s:SciChartSurface.YAxes> 
       <s:NumericAxis x:Name="Ch0" Style="{StaticResource YAxisStyle}" Id="Ch0" AxisTitle="Ch0" Grid.Row="0"/> 
       <s:NumericAxis x:Name="Ch1" Style="{StaticResource YAxisStyle}" Id="Ch1" AxisTitle="Ch1" Grid.Row="2" /> 
       <s:NumericAxis x:Name="Ch2" Style="{StaticResource YAxisStyle}" Id="Ch2" AxisTitle="Ch2" Grid.Row="4" /> 
       <s:NumericAxis x:Name="Ch3" Style="{StaticResource YAxisStyle}" Id="Ch3" AxisTitle="Ch3" Grid.Row="6" /> 
       <s:NumericAxis x:Name="Ch4" Style="{StaticResource YAxisStyle}" Id="Ch4" AxisTitle="Ch4" Grid.Row="8" /> 
       <s:NumericAxis x:Name="Ch5" Style="{StaticResource YAxisStyle}" Id="Ch5" AxisTitle="Ch5" Grid.Row="10" /> 
       <s:NumericAxis x:Name="Ch6" Style="{StaticResource YAxisStyle}" Id="Ch6" AxisTitle="Ch6" Grid.Row="12" /> 
       <s:NumericAxis x:Name="Ch7" Style="{StaticResource YAxisStyle}" Id="Ch7" AxisTitle="Ch7" Grid.Row="14" /> 
      </s:SciChartSurface.YAxes> 

      <s:SciChartSurface.ChartModifier> 
       <s:ModifierGroup> 
        <s:RubberBandXyZoomModifier IsXAxisOnly="True"/> 
        <s:ZoomExtentsModifier/> 
        <s:CursorModifier ShowAxisLabels="False" ShowTooltip="False"/> 
       </s:ModifierGroup> 
      </s:SciChartSurface.ChartModifier> 

      <s:SciChartSurface.Annotations> 

       <!-- Draws Bands behind each axis --> 
       <s:BoxAnnotation YAxisId="Ch0" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch0}" Y2="{Binding VisibleRange.Max, ElementName=Ch0}" Background="#11000000" AnnotationCanvas="BelowChart"/>

       <s:BoxAnnotation YAxisId="Ch3" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch3}" Y2="{Binding VisibleRange.Max, ElementName=Ch3}" Background="#44B0C4DE" AnnotationCanvas="BelowChart"/> 
       <s:BoxAnnotation YAxisId="Ch4" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch4}" Y2="{Binding VisibleRange.Max, ElementName=Ch4}" Background="#11000000" AnnotationCanvas="BelowChart"/> 
       <s:BoxAnnotation YAxisId="Ch5" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch5}" Y2="{Binding VisibleRange.Max, ElementName=Ch5}" Background="#44B0C4DE" AnnotationCanvas="BelowChart"/> 
       <s:BoxAnnotation YAxisId="Ch6" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch6}" Y2="{Binding VisibleRange.Max, ElementName=Ch6}" Background="#11000000" AnnotationCanvas="BelowChart"/> 
       <s:BoxAnnotation YAxisId="Ch7" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch7}" Y2="{Binding VisibleRange.Max, ElementName=Ch7}" Background="#44B0C4DE" AnnotationCanvas="BelowChart"/> 

       <s:AxisMarkerAnnotation X1="0.0" 
             Y1="0.0" 
             YAxisId="Ch0" 
             IsEditable="True" 
             LabelTemplate="{StaticResource AxisMarkerTemplate}" 
             PointerTemplate="{StaticResource DefaultAxisPointerTemplate}"/> 

       <s:AxisMarkerAnnotation X1="0.0" 
             Y1="0.0" 
             YAxisId="Ch1" 
             IsEditable="True" 
             LabelTemplate="{StaticResource AxisMarkerTemplate}" 
             PointerTemplate="{StaticResource DefaultAxisPointerTemplate}"/> 
      </s:SciChartSurface.Annotations>

Answer 1

有來自軸類GetDataValue的錯誤，不計算y軸偏移。 在我的一個項目中，我解決了這個類的問題：

class FixedAxisMarkerAnnotation : AxisMarkerAnnotation 
{ 
    protected override IComparable FromCoordinate(double coord, IAxis axis) 
    { 
     var coordinateCalculator = this.YAxis.GetCurrentCoordinateCalculator(); 

     if (!axis.IsXAxis) 
      coord += coordinateCalculator.CoordinatesOffset; 
     // 

     return base.FromCoordinate(coord, axis); 
    } 
}
