}

series["PointWidth"] = PointWidth; 绘制的宽度

series.XValueMember = XValueMember; 绑定数据的X轴显示数据的对应列名

series.YValueMembers = name; 绑定数据的Y轴显示数据的对应列名

series["DrawingStyle"] = "Cylinder"; 绘制图形的样式

series.ToolTip = "#VAL"; 鼠标移到上去的显示的Y轴对应的数据

series.ChartType = stype; 显示图形的样式此类型为枚举类型下面有我翻译的一点东东很多不准俺是英盲

this.DropDownList1.Items.Add(new ListItem("区域填充", "13"));

this.DropDownList1.Items.Add(new ListItem("条形", "7"));

this.DropDownList1.Items.Add(new ListItem("盒型图", "28"));

this.DropDownList1.Items.Add(new ListItem("气泡", "2"));

this.DropDownList1.Items.Add(new ListItem("烛台", "20"));

this.DropDownList1.Items.Add(new ListItem("竖形", "10"));

this.DropDownList1.Items.Add(new ListItem("空心圆", "18"));

下面是微软的枚举,简单的说下 new ListItem("累加列", "11") 后面的11 对应的就是 StackedColumn = 11,

// 摘要:

// Specifies a chart type for a System.Web.UI.DataVisualization.Charting.Series.

public enum SeriesChartType

{

// 摘要:

Point = 0,

Spline = 4,

// 摘要:

StepLine = 5,

// 摘要:

FastLine = 6,

// 摘要:

StackedBar = 8,

// 摘要:

// 摘要:

// 摘要:

SplineArea = 14,

// 摘要:

// 摘要:

Candlestick = 20,

// 摘要:

// Range chart type.

Range = 21,

// 摘要:

SplineRange = 22,

// 摘要:

RangeBar = 23,

// 摘要:

PointAndFigure = 32,

// 摘要:

// 摘要:

Pyramid = 34,

}

重点介绍的是饼图饼图有些特殊

/// <summary>

/// 适合样式有、饼图、空心饼图

/// </summary>

/// <param name="name"></param>

/// <param name="stype"></param>

/// <param name="xValues"></param>

/// <param name="yValues"></param>

/// <returns></returns>

public static Series SetSeriesStyle(string name, SeriesChartType stype, string[] xValues, double[] yValues)

{

Series series = new Series(name);

series.ChartType = stype;

// series["PointWidth"] = PointWidth;

series.Points.DataBindXY(xValues, yValues);

for (int i = 0; i < yValues.Count(); i++)

{

series.Points[i].LegendText = xValues[i] + " #VAL";

//series.Points[i].Label = xValues[i] + " #PERCENT{P1}";

//series.Points[i].Label = "#PERCENT{P1}";

}

series.ToolTip = "#VALX #PERCENT{P1}";

series["PieLabelStyle"] = "Disabled";

series.ChartArea = name;

series.Legend = name;

return series;

}

在这里详细介绍下

series.ToolTip = "#VALX #PERCENT{P1}"; 这个 #VALX 是用来获取饼图的实际数字的 #PERCENT{P1}是用来获取百分比的

我在在网上查饼图资料是居然有人用自己来计算这个虽然我不知道微软这个如何来计算的但是他饼图都能画出来百分比它还算不出来吗建议大家在学习这个控件的时候多看微软示例微软的已经很全了
