报表小示例

//引用命名空间
using WebChart;

//定义一个颜色数组,供循环时为不同的记录填充不同的颜色
private string[] myColor = new string[]
{
    "Tomato",//西红柿
    "Black",
    "Gold",
    "Blue",
    "Green",
    "Orange",
    "Pink",//粉红
    "Violet",//紫罗兰
    "Orchid",//淡紫色
    "Lime",//亮绿
    "Tan",//茶色
    "Red",
    "Navy"//橘红
};

//用静态方式示例了画出一条两个点的最简单折线.实际项目据此做循环而以.
private void doIt()
{
    //创建折线对象
    LineChart myChart = new LineChart();
    //为折线填充颜色
    myChart.Line.Color = Color.FromName(myColor[0]);

    //图例说明
    myChart.Legend = "折线一";
    //添加第一个点,参数一为x座标上的名称,参数二为y座标上的值
    myChart.Data.Add(new ChartPoint("一", float.Parse("100")));
    //添加第二个点

    "DodgerBlue",
    "Lime",
    "Tan",
    "Red",
    "GreenYellow",
    "DarkGreen",
    "DimGray",
    "Orchid"
};

//调用该方法生成柱状图
private void bindchart()
{
    //获取一个DataTable,具体函数略...
    DataTable dt = this.getdt();
    if (dt != null)
    {

            for (int i = 0; i < dt.Rows.Count; i++)
            {
                //创建对象
