我們要實現上圖中的效果,需要如下的操作:
打開集合編輯器,並點擊添加,如圖1、圖2
圖1 圖2VB: Private Sub TestChart4_Load(sender As Object, e As EventArgs) Handles MyBase.Load Dim matTable As New DataTable matTable.Columns.Add("XMember", GetType(String)) matTable.Columns.Add("YMember", GetType(Integer)) For i As Integer = 1 To 7 Step 1 Dim row As DataRow = matTable.NewRow row("XMember") = "10-" + (i + 25).ToString row("YMember") = 0 matTable.Rows.Add(row) Next matTable.Rows(0)("YMember") = 3 matTable.Rows(1)("YMember") = 1 matTable.Rows(3)("YMember") = 1 matTable.Rows(6)("XMember") = "11-01" Me.LineChart1.DataSource = matTable Me.LineChart1.DataBind() End Sub
C#: private void TestChart4_Load(object sender, EventArgs e) { DataTable matTable = new DataTable(); matTable.Columns.Add("XMember", typeof(string)); matTable.Columns.Add("YMember", typeof(int)); for (int i = 1; i <= 7; i += 1) { DataRow row = matTable.NewRow(); row["XMember"] = "10-" + (i + 25).ToString(); row["YMember"] = 0; matTable.Rows.Add(row); } matTable.Rows[0]["YMember"] = 3; matTable.Rows[1]["YMember"] = 1; matTable.Rows[3]["YMember"] = 1; matTable.Rows[6]["XMember"] = "11-01"; this.LineChart1.DataSource = matTable; this.LineChart1.DataBind(); }
綁定X軸的值,如圖3
綁定Y軸的值,如圖4
