有过webchart的前辈，请给解释下面代码段的意思，最好是每句，为什么有的属性或方法根本没有



C1.Win.C1Chart.Label lbl = C1WebChart1.ChartLabels.LabelsCollection.AddNewLabel();

lbl.Text = string.Format(" {0}% ", float.Parse(dv[i][" value "].ToString()));

lbl.Compass = LabelCompassEnum.Radial;

lbl.Offset = 20;

lbl.Connected = true;

lbl.Visible = true;

lbl.AttachMethod = AttachMethodEnum.DataIndex;

AttachMethodData am = lbl.AttachMethodData;

am.GroupIndex = 0;

am.SeriesIndex = i;

am.PointIndex = 0;

//.下载ComponentOne.Sutdio.Enterprise.2006.v1.for.dotNet1.1.zip(此版本针对.Net 1.1),解压,安装里面的ASP.NET控件安装包,找到安装目录,把BIN目录下的C1.Web.C1WebChart.dll和C1.win.C1Chart.dll拷贝到你项目的BIN目录下,并引用进项目





//加标签

C1.Win.C1Chart.Label lbl = C1WebChart1.ChartLabels.LabelsCollection.AddNewLabel();



//右侧相应项目标签的文本显示=取（dv表中i行名为Value的列的值）%100的百分数

lbl.Text = string.Format(" {0}% ", float.Parse(dv[i][" value "].ToString())); 



 

lbl.Compass = LabelCompassEnum.Radial;

lbl.Offset = 20;

lbl.Connected = true;

lbl.Visible = true;



//AttachMethodData类被图表的Label对象和Label对象的Label.MethodData属性结合使用用于确定Label代替或者隶属于图表，AttachMethodData对象的每个属性仅仅意味着和Label.AttachMethod值相关



lbl.AttachMethod = AttachMethodEnum.DataIndex;

AttachMethodData am = lbl.AttachMethodData;

am.GroupIndex = 0;

am.SeriesIndex = i;

am.PointIndex = 0;
