第一个简单的chart： spline// Create new data series and set it's visualattributes
       Series series = new Series("Spline");
       series.ChartType = SeriesChartType.Spline;
       series.BorderWidth = 3;
       series.ShadowOffset = 2;

       // Populate new series with data
       series.Points.AddY(67);
       series.Points.AddY(57);
       series.Points.AddY(83);
       series.Points.AddY(23);
       series.Points.AddY(70);
       series.Points.AddY(60);
       series.Points.AddY(90);
       series.Points.AddY(20);

// Add series into the chart's series collection
Chart1.Series.Add(series);

// Populate series with random data
       Random random = new Random();
       for (int pointIndex = 0; pointIndex < 10;pointIndex++)
       {
           Chart1.Series["Series1"].Points.AddY(random.Next(45, 95));
           Chart1.Series["Series2"].Points.AddY(random.Next(5, 75));
       }

       // Set series chart type
       Chart1.Series["Series1"].ChartType = SeriesChartType.Line;
       Chart1.Series["Series2"].ChartType = SeriesChartType.Spline;

       // Set point labels
       Chart1.Series["Series1"].IsValueShownAsLabel = true;
       Chart1.Series["Series2"].IsValueShownAsLabel = true;

// Enable X axis margin

显示column类型图
// Create new data series and set it's visual attributes
       Series series = new Series("FlowRead");
       series.ChartType = SeriesChartType.Column;
       series.BorderWidth = 3;
       series.ShadowOffset = 2;

// Add series into the chart's series collection
Chart1.Series.Add(series);

很多点，效率还可以
// Fill series data
       double yValue = 50.0;
       Random random = new Random();
       for (int pointIndex = 0; pointIndex < 20000;pointIndex++)
       {
           yValue = yValue + (random.NextDouble() * 10.0 - 5.0);
           Chart1.Series["Series1"].Points.AddY(yValue);
       }

// Set fast line chart type
Chart1.Series["Series1"].ChartType = SeriesChartType.FastLine;

}

日期，xy类型
// Create a new random number generator
Random rnd = new Random();

// Data points X value is using current date
DateTime date = DateTime.Now.Date;

       // Add points to the stock chart series
       for (int index = 0; index < 10; index++)
       {
           Chart1.Series["Series1"].Points.AddXY(
               date,               // X value is a date
               rnd.Next(40,50));    //Close Y value

           // Add 1 day to our X value
           date = date.AddDays(1);
       }
