推荐答案

我找到了解决方案.我们可以使用TextAnnotation类来实现这一目的.

I have found the solution. We can use TextAnnotation class to achieve this.

TextAnnotation a = default(TextAnnotation);            

for (int i = 0; i < chart1.Series[0].Points.Count; i++)            
{                
a = new TextAnnotation();                
a.AxisX = chart1.ChartAreas[0].AxisX;                a.AxisY = chart1.ChartAreas[0].AxisY;                a.AnchorX = chart1.Series[0].Points[i].XValue;                
a.AnchorY = chart1.Series[0].Points[i].YValues[0];                
a.AnchorAlignment = ContentAlignment.TopCenter;                a.Text = "

" +(chart1.Series [0] .Points [i] .YValues [0]- chart1.Series [0] .Points [i] .YValues [1]).ToString();    //dp.YValues [0] .ToString(); chart1.Annotations.Add(a);              }

" + (chart1.Series[0].Points[i].YValues[0] - chart1.Series[0].Points[i].YValues[1]).ToString();    //dp.YValues[0].ToString();                chart1.Annotations.Add(a);                }
