在.Net4.0框架中，微软已经将Mschart控件集成了进来，以前一直在web下面用过，原来winform下的Mschart控件更加简单更加方便，今天我们用mschart绘制一个多曲线图，话不多说，直接上效果图：
发现，MsChart 的显示效果还是不错的。
代码如下，供大家参考：
public partial class FrmMain : Form
{
public FrmMain()
{
InitializeComponent();
InitializeChart();
this.Load += new EventHandler(FrmMain_Load);
this.myChart.GetToolTipText += new EventHandler<tooltipeventargs>(myChart_GetToolTipText);
}
void FrmMain_Load(object sender, EventArgs e)
{
float[][] data = new float[3][];
//第一条数据
data[0] = new float[10] { 1.3f, 2.5f, 2.1f, 3.3f, 2.8f, 3.9f, 4.3f, 3.6f, 4.2f, 3.6f };
//第二条数据
data[1] = new float[12] { -2f, -1.3f, 0.1f, 0.5f, -1.5f, 0.7f, 1f, 1.4f, 1.9f, 2f, 2.6f, 3.1f };
//第三条数据
data[2] = new float[10] { 7.8f, 9.2f, 6.5f, 8.3f, 9.0f, 5.9f, 6.3f, 7.2f, 8.8f, 9.8f };
for (int i = 0; i < data.Length; i++)
{
//横坐标时间
DateTime dt = DateTime.Now.Date;
Series series = this.SetSeriesStyle(i);
for (int j = 0; j < data[i].Length; j++)
{
series.Points.AddXY(dt, data[i][j]);
dt = dt.AddDays(1);
}
this.myChart.Series.Add(series);
}
}
private void myChart_GetToolTipText(object sender, ToolTipEventArgs e)
{
if (e.HitTestResult.ChartElementType == ChartElementType.DataPoint)
{
int i = e.HitTestResult.PointIndex;
DataPoint dp = e.HitTestResult.Series.Points[i];
e.Text = string.Format("时间:{0};数值:{1:F1} ", DateTime.FromOADate(dp.XValue),dp.YValues[0]);
}
}

另外附上微软Demo的下载地址：http://archive.msdn.microsoft.com/mschart/Release/ProjectReleases.aspx?ReleaseId=4418
Demo 分为WEB版本和WinForm版本，样式和图表内容很全，希望对大家有所帮助。
