Question

目前我正在尝试用WPF图表工具包制作图表，
要求是Y轴应如下图所示：
Y-axis

描述了 * 0~84为D级 * 85~99级为B级 ...

我不确定图表工具包是否可以制作这种类型的Y轴刻度如果图表工具包不支持上面的话，我会尝试将TextBox控件直接放入画布中“Level *”标签，我仍有问题，如何只显示85,100,115作为Y轴的比例。

任何帮助将不胜感激。谢谢。

您可以尝试将Converter用作图表的轴标签。像这样的东西： XAML

<chartingToolkit:Chart Name="chart1"  >
 <chartingToolkit:Chart.Resources>
  <HideConverter x:Key="HideConverter1" />
 </chartingToolkit:Chart.Resources>
 <chartingToolkit:Chart.Axes>
  <chartingToolkit:LinearAxis Orientation="Y" ShowGridLines="False"  Interval="5" Minimum="0" Maximum="150" >
   <chartingToolkit:LinearAxis.AxisLabelStyle>
    <Style TargetType="chartingToolkit:AxisLabel">
     <Setter Property="Template">
      <Setter.Value>
       <ControlTemplate TargetType="chartingToolkit:AxisLabel">
        <TextBlock DataContext="{TemplateBinding FormattedContent}" Text="{Binding Converter={StaticResource HideConverter1}}" />
       </ControlTemplate>
      </Setter.Value>
     </Setter>
    </Style>
   </chartingToolkit:LinearAxis.AxisLabelStyle>
  </chartingToolkit:LinearAxis>
 </chartingToolkit:Chart.Axes>
</chartingToolkit:Chart>

并且在你的代码中，转换器是

public class HideConverter : IValueConverter
{

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        // value is the current tick on the Y axis
        int x = int.Parse(value.ToString());
        switch (x)
        {
            case 85:
            case 100:
            case 115:
                return value;
            case 40: // I set 40 to be in the middle between 0 and 85
                return "Level D";
            case 90:
                return "Level C";
            case 110:
                return "Level B";
            case 130:
                return "Level A";
            default:
                return null;;
        }
        return null;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
