我扩展了PointBase，在app.xaml配置风格如下
<Style x:Name="TrackPointStyle" TargetType="AHGeometry:TrackPointGeo">
<!--轨迹点和标签的样式控制-->
<!--<Setter Property="RenderTransformOrigin" Value="0,1" />-->
<!--<Setter Property="AnchorPoint" Value="0.5,0.5" />-->
<Setter Property="Width" Value="500" />
<Setter Property="Height" Value="200" />
<Setter Property="Opacity" Value="0.88" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="AHGeometry:TrackPointGeo">
<Grid Name ="RootElement">
<Grid.RenderTransform>
<ScaleTransform x:Name="_ScaleTransform" ScaleX="0" ScaleY="1"/>
</Grid.RenderTransform>
<Path RenderTransformOrigin="0,1" Fill="#FFFD0C0C" Stretch="Fill" Stroke="Black" Height="8" Width="8" Canvas.Left="21" Canvas.Top="104" Data="M7.5,4 C7.5,5.9329967 5.9329967,7.5 4,7.5 C2.0670035,7.5 0.5,5.9329967 0.5,4 C0.5,2.0670035 2.0670035,0.5 4,0.5 C5.9329967,0.5 7.5,2.0670035 7.5,4 z"/>
<Path RenderTransformOrigin="0,1" Fill="#FFED0B0B" Stretch="Fill" Stroke="#FFF51111" Height="43" Width="41" UseLayoutRounding="False" Canvas.Left="26" Canvas.Top="64" Data="M29,104 L69,62"/>
<TextBox RenderTransformOrigin="0,1" Name="_TextBox" Background="#CCFFFFFF" Height="24" Width="125" Canvas.Left="67" Canvas.Top="49" Text="TextBox" TextWrapping="Wrap"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
代码如下
public class TrackPointGeo : PointBase
{
protected TextBox _textBox;
public TrackPointGeo()
{
Style = Application.Current.Resources["TrackPointStyle"] as System.Windows.Style;
}
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
}
第一个path为点的样式，第二个path为从第一个path拉一条线，第三个为点的标签我用了textBox，可是显示出来后都在点上，并且第二个path和textBox的中心点都与第一个path相重合。怎么配置才能达到我要的效果？谢谢!
