C# winform怎么用chart控件实时绘制采集到的速度和扭力曲线

[qq_15379521]

菜鸟接触C#时间不长 跪求大神指导

[NetSuite - 张老师]

好高级的样子，C#还没学到这个东东

[lsy999]

我覺得是一般

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()
        {
            DataTable tableInfo = new DataTable();

            DataColumn dctime = new DataColumn("Time", Type.GetType("System.String"));
            DataColumn dcCity = new DataColumn("City", Type.GetType("System.String"));
            DataColumn dcCount = new DataColumn("Count", Type.GetType("System.Int32"));
            tableInfo.Columns.Add(dctime);
            tableInfo.Columns.Add(dcCity);
            tableInfo.Columns.Add(dcCount);
            DataRow dr = tableInfo.NewRow();
            dr["Time"] = "1:00";
            dr["City"] = "10";
            dr["Count"] = "15";
            tableInfo.Rows.Add(dr);
            DataRow dr1 = tableInfo.NewRow();
            dr1["Time"] = "2:00";
            dr1["City"] = "12";
            dr1["Count"] = "19";
            tableInfo.Rows.Add(dr1);
            DataRow dr2 = tableInfo.NewRow();

            dr2["Count"] = "25";
            tableInfo.Rows.Add(dr2);
            DataRow dr3 = tableInfo.NewRow();
            dr3["Time"] = "4:00";
            dr3["City"] = "14";
            dr3["Count"] = "10";
            tableInfo.Rows.Add(dr3);

            DataRow dr4 = tableInfo.NewRow();
            dr4["Time"] = "5:00";
            dr4["City"] = "15";
            dr4["Count"] = "11";
            tableInfo.Rows.Add(dr4);

            DataRow dr5 = tableInfo.NewRow();
            dr5["Time"] = "6:00";
            dr5["City"] = "16";
            dr5["Count"] = "17";
            tableInfo.Rows.Add(dr5);

            DataRow dr6 = tableInfo.NewRow();
            dr6["Time"] = "7:00";

            return tableInfo;
        }

@wind_cloud2011 我主要不知道该怎么实时更新数据啊 你这样的话数据绑定死的 我现在也是先这么写的 朋友说用list好像比table好点 不过还是不会

[OTCE]

你可以绑定数据源啊

private void zkButton1_Click(object sender, EventArgs e)
		{
			Random rand = new Random();
			var list = new List<ChartTestData>();
			int i = 0;
			while (i < 30)
			{
				list.Add(new ChartTestData(i.ToString(), rand.Next(0, 100), rand.Next(0, 100)));
				i++;
			}
			this.bindingSource1.DataSource = list;
			this.Chart.DataBind();
		}

public class ChartTestData
	{
		public string name { get; set; }
		public decimal value1 { get; set; }
		public decimal value2 { get; set; }

		public ChartTestData()
		{ }
		public ChartTestData(string name, decimal value1, decimal value2)
		{
			this.name = name;
			this.value1 = value1;
			this.value2 = value2;
		}
	}

如果我没有理解错，可以使用心电图的方式，实时刷新，删除一个旧的数据点同时再添加一个新的数据点。

[nongfuxu123]

看看这样操作行嘛 新建一个集合保存输入的数据； 在窗体中新建一个PANNEL，在paint事件中画曲线； 若需要伸缩画面，画画坐标、数值，经过比例因子计算后，再在画布上显示。

[nongfuxu123]

另外，若要查看记录数据的某一段，则建立一个时间轴变量， 然后根据显示比例，在数据集合中提取相应数据段来 画在画布上。

楼主怎么解决的啊？
