这是我用于图表的代码，一切正常，但是当我添加 LineSeries.ToolTip 标记时出现此错误： xml 命名空间http://schemas.infragistics.com中不存在标记 LineSeries.ToolTip /xaml

<ig:XamDataChart Name="Datachar" VerticalZoomable="True" HorizontalZoomable="True" Width="550" Height="220">
                                <ig:XamDataChart.Axes>
                                    <ig:CategoryXAxis x:Name="xAxis" ItemsSource="{Binding Data}" Label="{}{Date:MM/yyyy}">

在您定义工具提示的 XAML 中存在错误。具体应该是元素的子元素，目前不是。更新的标记：

<ig:XamDataChart Name="Datachar" VerticalZoomable="True" HorizontalZoomable="True" Width="550" Height="220">
    <ig:XamDataChart.Axes>
        <ig:CategoryXAxis x:Name="xAxis" ItemsSource="{Binding Data}" Label="{}{Date:MM/yyyy}">
            <ig:CategoryXAxis.LabelSettings>
                <ig:AxisLabelSettings Location="OutsideTop" Extent="45" VerticalAlignment="Center" Visibility="Visible" />
            </ig:CategoryXAxis.LabelSettings>
        </ig:CategoryXAxis>
        <ig:NumericYAxis x:Name="yAxis">
            <ig:NumericYAxis.LabelSettings>
                <ig:AxisLabelSettings Location="OutsideLeft" Extent="50" VerticalAlignment="Center" Visibility="Visible"/>
            </ig:NumericYAxis.LabelSettings>
        </ig:NumericYAxis>
    </ig:XamDataChart.Axes>

    <ig:XamDataChart.Series>
        <ig:LineSeries ItemsSource="{Binding Data}" XAxis="{Binding ElementName=xAxis}" YAxis="{Binding ElementName=yAxis}" ValueMemberPath="Value" Thickness="1" MarkerType="None"/>
        <ig:LineSeries ItemsSource="{Binding Index}" XAxis="{Binding ElementName=xAxis}" YAxis="{Binding ElementName=yAxis}" ValueMemberPath="Value" Thickness="1" MarkerType="None">
        <ig:LineSeries.ToolTip>
            <StackPanel>
                <StackPanel Orientation="Horizontal">
                    <TextBlock Margin="2" Text="Value" VerticalAlignment="Center"></TextBlock>
                    <TextBlock Margin="2" Text="{Binding Item.Value, StringFormat='0,0'}" VerticalAlignment="Center" />
                </StackPanel>
            </StackPanel>
        </ig:LineSeries.ToolTip>
            </ig:LineSeries>
    </ig:XamDataChart.Series>
</ig:XamDataChart>

我所做的更改是将第二个系列元素的结尾更改为以“>”而不是“/>”结尾，并在工具提示之后添加了结束标记。
