C#winform怎么用chart控件实时绘制采集到的速度和扭力曲线

给你一个例子
private void button1_Click(object sender, EventArgs e)
{
chart1.DataSource = GetData();
// Set series members names for the X and Y values
chart1.Series["Series1"].XValueMember = "Time";
chart1.Series["Series1"].YValueMembers = "City";

chart1.Series["Series2"].XValueMember = "Time";
chart1.Series["Series2"].YValueMembers = "Count";

// Data bind to the selected data source
chart1.DataBind();

// 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
chart1.ChartAreas["ChartArea1"].AxisX.IsMarginVisible = true;
// Enable 3D, and show data point marker lines
//chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;
chart1.Series["Series1"]["ShowMarkerLines"] = "True";
chart1.Series["Series2"]["ShowMarkerLines"] = "True";

}

private DataTable GetData()
{

tableInfo.Columns.Add(dcCount);
DataRow dr = tableInfo.NewRow();
dr["Time"] = "1:00";
