我有以下圖表:WPF工具包圖表 - 自定義工具提示 - 顯示出複雜的依賴值
<cht:Chart ...>
<cht:Chart.Series>
<cht:LineSeries Name="LineSeries" Title="a"
DependentValueBinding="{Binding Path=Value}"
IndependentValueBinding="{Binding Path=Key}"
ItemsSource="{Binding Path=SourceCollection}"
IsSelectionEnabled="True"
DataPointStyle="{DynamicResource SmallPointStyle}">
</cht:LineSeries>
</cht:Chart.Series>
</cht:Chart>
而且DataPointStyle:
<Style TargetType="cht:LineDataPoint">
<Setter Property="Width" Value="2" />
<Setter Property="Height" Value="2" />
<Setter Property="DependentValueStringFormat" Value="{}{0:0.00}"/>
</Style>
<Style x:Key="SmallPointStyle" TargetType="cht:LineDataPoint" BasedOn="{StaticResource {x:Type cht:LineDataPoint}}">
<Setter Property="BorderBrush" Value="Orange"/>
<Setter Property="Background" Value="Orange"/>
</Style>
的源集合是KeyValuePair列表。 該應用程序正常工作。
我遇到了一個問題,因爲我想使用KeyValuePair>的集合,其中doubleA是提取的數據,doubleB是doubleA的標準化值,基於範圍。所以我需要改變檢測LineSeries是:
<cht:Chart ...>
<cht:Chart.Series>
<cht:LineSeries Name="LineSeries" Title="a"
DependentValueBinding="{Binding Path=Value.Value}"
IndependentValueBinding="{Binding Path=Key}"
ItemsSource="{Binding Path=SourceCollection}"
IsSelectionEnabled="True"
DataPointStyle="{DynamicResource SmallPointStyle}">
</cht:LineSeries>
</cht:Chart.Series>
</cht:Chart>
它的工作原理如我所料,但我需要在工具提示中真正的價值(Value.Key),而不是DependentValue顯現。無論如何要做到這一點?
