希望这个对你能有所帮助：先看效果图：

public Form1()

{

InitializeComponent();

var serieItem = this.chart1.Series[0];

serieItem.ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Spline;

//X轴坐标 值类型为 时间类型

serieItem.XValueType = System.Windows.Forms.DataVisualization.Charting.ChartValueType.Time;

serieItem.IsValueShownAsLabel = true;

serieItem.IsXValueIndexed = true;

DataTable table = GetDataSource();

DataPoint pointItem = null;

for (int i = 0; i

{

pointItem = new DataPoint();

pointItem.SetValueXY(table.Rows[i]["TimeValue"], table.Rows[i]["Value"]);

serieItem.Points.Add(pointItem);

}

}

DataTable GetDataSource()

{

DataTable table = new DataTable();

table.Columns.Add("Value", typeof(double));

table.Columns.Add("TimeValue", typeof(DateTime));

DataRow row = table.NewRow();

row["Value"] = 45;

row["TimeValue"] = DateTime.Parse("2010-08-08 9:30");

table.Rows.Add(row);

row = table.NewRow();

row["Value"] = 50;

row["TimeValue"] = DateTime.Parse("2010-08-08 10:00");

table.Rows.Add(row);

row = table.NewRow();

row["Value"] = 55;

row["TimeValue"] = DateTime.Parse("2010-08-08 10:30");

table.Rows.Add(row);

row = table.NewRow();

row["Value"] = 45;

row["TimeValue"] = DateTime.Parse("2010-08-08 11:00");

table.Rows.Add(row);

row = table.NewRow();

row["Value"] = 52;

row["TimeValue"] = DateTime.Parse("2010-08-08 11:30");

table.Rows.Add(row);

row = table.NewRow();

row["Value"] = 43;

row["TimeValue"] = DateTime.Parse("2010-08-08 12:00");

table.Rows.Add(row);

row = table.NewRow();

row["Value"] = 60;

row["TimeValue"] = DateTime.Parse("2010-08-08 12:30");

table.Rows.Add(row);

return table;

}

提示：

serieItem.XValueType = System.Windows.Forms.DataVisualization.Charting.ChartValueType.Time;

这句就是设置 X 轴 值的类型。
