Question

我使用了SciChart组件的VerticallStackedAxes，并为每个NumericAxis添加了7个AxisMarkerAnnotation，但除了第一个之外，AxisMarkerAnnotations不可拖动。

这是我的UserControl代码的一部分：

<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="Ch1" CoordinateMode="RelativeX" X1="0" X2="1" Y1="{Binding VisibleRange.Min, ElementName=Ch1}" Y2="{Binding VisibleRange.Max, ElementName=Ch1}" Background="#44B0C4DE" AnnotationCanvas="BelowChart"/>

                <s:AxisMarkerAnnotation X1="0.0" 
                                        Y1="0.0"

                                        PointerTemplate="{StaticResource DefaultAxisPointerTemplate}"/>

                <s:AxisMarkerAnnotation X1="0.0" 
                                        Y1="0.0"

            </s:SciChartSurface.Annotations>

Answer 1

来自轴类的GetDataValue中存在一个错误，它不会计算yaxis偏移量。在我的一个项目中，我修复了这个类的问题：

DEFINE QLOCAL(CQLOCAL) CLUSTER('YOURCLUSTER') CLWLUSEQ(ANY)

Answer 2

我能够重现这个问题，并且正在调查它。您也可以在此处跟踪问题的进展情况===＆gt;＆gt;＆gt; https://abtsoftware.myjetbrains.com/youtrack/issue/SC-4202
