赢形式图表 [英] Win Form Charting

问题描述

我可能会问错了问题，但我需要的是添加一个指南专线我的窗户形成的图表。换句话说，我有一个简单的数据系列的图表，我需要借鉴的合格分数y轴，或80％的线路。我不想添加第二个系列作为第一个系列有数据点的人数不详。有一个简单的方法来简单地画在y轴上一条线？
下面的虚线就是我拍摄（它不需要箭头）

尝试添加的带状

例如：

  VAR系列= chart1.Series [0]; //一系列对象
 VAR chartArea = chart1.ChartAreas [series.ChartArea] 
 chartArea.AxisY.StripLines.Add（新带状
 {
 BorderDashStyle = ChartDashStyle.Dash，
 BORDERCOLOR = Color.DarkBlue，
间隔= 10 //这里是您的y值
}）; 
  

I may be asking the wrong question, but what I need is to add a "Guide Line" to my windows form chart. In other words I have a chart with a simple data series and I need to draw a line on the y axis at the passing score, or 80%. I don't want to add a second series as the first series has an undetermined number of data points. Is there a simple way to simply draw one line on the y axis? The dashed line below is what I am shooting for(it does not need the arrows).

解决方案

Try to add a StripLine
For example:

var series = chart1.Series[0]; //series object
var chartArea = chart1.ChartAreas[series.ChartArea];
chartArea.AxisY.StripLines.Add(new StripLine
                                           {
                                               BorderDashStyle = ChartDashStyle.Dash,
                                               BorderColor = Color.DarkBlue,
                                               Interval = 10//Here is your y value
                                           });
