曲线图：

   ChartPointCollection d = new ChartPointCollection();

     Chart c = new LineChart(d,Color.Blue);

柱状图：

   Chart c = new StackedColumnChart();

   ChartPointCollection d;

d = c.Data;

饼状图：

   ChartPointCollection data = new ChartPointCollection();

PieChart c = new PieChart(data, Color.Blue);

c.Colors = new Color[] { Color.Red, Color.Blue, Color.Yellow, Color.Cyan, Color.AntiqueWhite, Color.RosyBrown };

添加数据：

data.Add(new ChartPoint("Ene", 40));

data.Add(new ChartPoint("Feb", 40));

data.Add(new ChartPoint("Mar", 30));

data.Add(new ChartPoint("Abr", 20));

data.Add(new ChartPoint("May", 10));

data.Add(new ChartPoint("Jun", 25));
