使用 C# 查找 live 的区域部分

Question

我已经这样做了，使用 mschart 控件为图表的一部分创建单击事件处理程序，图表如下

和这样的代码

private void targetChartmouse_Click(object sender, MouseEventArgs e)
{ 
  try
  {
    var pos = e.Location;
    var results = kpiChartControl.HitTest(pos.X, pos.Y, false, ChartElementType.DataPoint);
    foreach (var result in results)
    {
      if (result.ChartElementType == ChartElementType.DataPoint)
      { 
        //do something....
      }
    }        
  }
}

当我们单击图表（在图表的每个部分）时，它工作正常，但我只想在单击实时（绿色）时执行某些操作，而不是在每个部分上执行某些操作。是否可以找到实时区域（绿色）

是否可以使用c#？

我正在做winforms应用程序

修改代码

     public void targetChartmouse_Click(object sender, MouseEventArgs e)
   {
  Series statusseries = new Series();
  Series liveseries = null;

Answer 1

这可能有效：

try
{
  var pos = e.Location;
  var results = kpiChartControl.HitTest(pos.X, pos.Y, false, ChartElementType.DataPoint);
  foreach (var result in results)
  {
    if (result.ChartElementType == ChartElementType.DataPoint)
    {
      if (result.Series.Points[result.PointIndex].AxisLabel == "Live")
      {
        Console.WriteLine("success?");
      }
    }
  }  
}

Answer 2

也许您可以使用 [result.PointIndex(http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization) 获取 DatePoint。 Charting.hittestresult.pointindex.aspx) 和 结果.Series。

if(result.Series.Points.Item[result.PointIndex].Label == "Live") {
    // ...
}
