在ms图表数据点中设置自定义标签

我正在使用ms图表在asp.net mvc3中创建图表！在ms图表数据点中设置自定义标签

我创建了该图。现在我想在特定的数据点上设置一些文本。例如在（185,90）这里是我的代码

    }

我尝试使用链接 Adding text , image to asp.net chart control 但标签未显示。我也想用0,120,130，... 和y轴开始x到0,20,30 有没有可能？任何帮助appericiated

你应该首先创建一个数据点，然后将其添加到系列。例如：

DataPoint dp = new DataPoint(); 
dp4.Font = dp_font; 
dp4.XValue = 185; 
dp4.SetValueY(90); 
dp4.Label = "Label text"; 

Series["bmi30"].Points.Add(dp)
