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
VB: Private Sub TestChart_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 12 Step 1 Dim row As DataRow = matTable.NewRow row("XMember") = i.ToString + "月" row("YMember") = 0 matTable.Rows.Add(row) Next matTable.Rows(7)("YMember") = 20000 matTable.Rows(8)("YMember") = 300000 matTable.Rows(9)("YMember") = 150000 matTable.Rows(10)("YMember") = 40000 Me.BarChart2.DataSource = matTable Me.BarChart2.DataBind() End SubC#: private void TestChart1_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 <= 12; i += 1) { DataRow row = matTable.NewRow(); row["XMember"] = i.ToString() + "月"; row["YMember"] = 0; matTable.Rows.Add(row); } matTable.Rows[7]["YMember"] = 20000; matTable.Rows[8]["YMember"] = 300000; matTable.Rows[9]["YMember"] = 150000; matTable.Rows[10]["YMember"] = 40000; this.BarChart2.DataSource = matTable; this.BarChart2.DataBind(); } }
綁定X軸的值,如圖3
綁定Y軸的值,如圖4
