【问题描述】:
我在 WPF 项目中使用 Silverlight 工具包,我想在我可以指定的 Y 轴值处向柱形图中添加一条红色虚线。我已经修改了图表模板并成功添加了一条线,但我不确定如何让这条线显示在我想要的 y 轴值以及如何让它横跨整个图表。这是我到目前为止的图表图片:
这是我用来生成它的图表模板 XAML 代码:
<charting:Chart Name="chartUsageHours" Grid.Column="1" BorderThickness="0" Padding="0" Loaded="chartUsageHours_Loaded">
<charting:Chart.Template>
<ControlTemplate TargetType="{x:Type charting:Chart}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<datavis:Title Content="{TemplateBinding Title}" Style="{TemplateBinding TitleStyle}" />
<chartingprimitives:EdgePanel Name="ChartArea" Style="{TemplateBinding ChartAreaStyle}" Grid.Row="1" Margin="0,0,0,0">
<Grid Panel.ZIndex="-1" Style="{TemplateBinding PlotAreaStyle}" />
<Border Panel.ZIndex="10" BorderBrush="#FF919191" BorderThickness="1, 0, 0, 1" />
<Grid Name="HoursThresholdContainer" Canvas.ZIndex="1" Background="Transparent">
<Grid Name="HoursThreshold">
<Line Name="Horizontal" HorizontalAlignment="Stretch" X1="0" Y1="100" X2="600" Y2="100" Stroke="Red" StrokeDashArray="4, 2"/>
</Grid>
</Grid>
</chartingprimitives:EdgePanel>
</Grid>
</Border>
</ControlTemplate>
</charting:Chart.Template>
<charting:Chart.Series>
<charting:StackedColumnSeries Visibility="{Binding Include_OnTimeVsFitTime, Converter={StaticResource BooleanToVisibilityConverter}}">
<charting:StackedColumnSeries.IndependentAxis>
<charting:CategoryAxis Orientation="X" SortOrder="None" ShowGridLines="False">
<charting:CategoryAxis.AxisLabelStyle>
<Style TargetType="charting:AxisLabel">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="charting:AxisLabel">
<TextBlock Text="{Binding Converter={StaticResource DateStringConverter}}" FontSize="8">
<TextBlock.LayoutTransform>
<RotateTransform Angle="-90"/>
</TextBlock.LayoutTransform>
</TextBlock>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</charting:CategoryAxis.AxisLabelStyle>
</charting:CategoryAxis>
</charting:StackedColumnSeries.IndependentAxis>
<charting:SeriesDefinition ItemsSource="{Binding ChartUsageHours}" DependentValuePath="Value" IndependentValuePath="Key" />
<charting:SeriesDefinition ItemsSource="{Binding ChartOnTimeHours}" DependentValuePath="Value" IndependentValuePath="Key" />
</charting:StackedColumnSeries>
<charting:StackedColumnSeries Visibility="{Binding DontInclude_OnTimeVsFitTime, Converter={StaticResource BooleanToVisibilityConverter}}">
<charting:SeriesDefinition ItemsSource="{Binding ChartUsageHours}" DependentValuePath="Value" IndependentValuePath="Key" />
</charting:StackedColumnSeries>
</charting:Chart.Series>
</charting:Chart>
有人知道怎么做吗?
谢谢, 保罗
