如何为 wpf 工具包 lineseries 图表中的每个单独数据点自定义工具提示？

Question

我看到了几个关于为单行系列制作自定义工具提示的问题。

我需要每个数据点的自定义工具提示。我想在工具提示中添加更多内容，而不仅仅是依赖值路径和独立值路径。

Example I have 2 data points on the same line one with a value(Y-axis) of 2, date(x-axis) of 4/28/2016, and configuration of A. The other has a value of 3, date of 4/29/2016, and configuration of B.

如何显示配置？这一切都是在代码背后完成的，因为我有一个动态数量的线系列。所以我不能只为 xaml.

中的每个线条系列分配样式

var MyLineSeries = new LineSeries();
lMyLineSeries.DependentValuePath = "Y";
lMyLineSeries.IndependentValuePath = "X";
lMyLineSeries.DataPointStyle = lToolTipDataPointStyle;

这是我创建工具提示样式的代码。

var lToolTipDataPointStyle = new Style(typeof(LineDataPoint));
var lTemplate = new ControlTemplate(typeof(LineDataPoint));
var lGridElement = new FrameworkElementFactory(typeof(Border));

//Tooltip
var lStackPanel = new StackPanel();

var lValueContentControl = new ContentControl();
lValueContentControl.SetBinding(ContentControl.ContentProperty, new Binding(myLineSeries.DependentValuePath));
lValueContentControl.ContentStringFormat = "Value: {0}";

var lConfigurationContentControl = new ContentControl();
lConfigurationContentControl.SetBinding(ContentControl.ContentProperty, new Binding())//This is what Idk what to bind to???

lConfigurationContentControl.ContentStringFormat = "Configuration: {0}";

lStackPanel.Children.Add(lValueContentControl);
lStackPanel.Children.Add(lConfigurationContentControl);

lGridElement.SetValue(ToolTipService.ToolTipProperty, lStackPanel);


var lEllipseElement = new FrameworkElementFactory(typeof(Ellipse));
lEllipseElement.SetValue(Ellipse.StrokeThicknessProperty, new TemplateBindingExtension(Border.BorderThicknessProperty));
lEllipseElement.SetValue(Ellipse.StrokeProperty, new TemplateBindingExtension(Border.BorderBrushProperty));
lEllipseElement.SetValue(Ellipse.FillProperty, new TemplateBindingExtension(Grid.BackgroundProperty));

lGridElement.AppendChild(lEllipseElement);
lTemplate.VisualTree = lGridElement;

var lTemplateSetter = new Setter();
lTemplateSetter.Property = LineDataPoint.TemplateProperty;
lTemplateSetter.Value = lTemplate;

lToolTipDataPointStyle.Setters.Add(lTemplateSetter);

return lToolTipDataPointStyle;

我通过使用 Tag on the Line 系列弄明白了。

myLineSeries.Tag = "Configuration";
var lConfigurationContentControl = new ContentControl();
lConfigurationContentControl.SetBinding(ContentControl.ContentProperty, new Binding(myLineSeries.Tag.ToString()))

lConfigurationContentControl.ContentStringFormat = "Configuration: {0}";
