.Net语言 APP开发平台——Smobiler学习日志：如何在手机上实现折线图表

一、目标样式

1.从工具栏上的”Smobiler Components”拖动一个PieChart控件到窗体界面上

2.修改PieChart的属性

a.CenterText属性

b.DefaultColors属性

c.Load事件（添加数据）

VB：
Private Sub TestChart2_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 4 Step 1
Dim row As DataRow = matTable.NewRow
matTable.Rows.Add(row)
Next
matTable.Rows(0)("XMember") = "餐饮"
matTable.Rows(1)("XMember") = "住宿"
matTable.Rows(2)("XMember") = "长途"
matTable.Rows(3)("XMember") = "通讯"

matTable.Rows(0)("YMember") = 740.0
matTable.Rows(1)("YMember") = 280.0
matTable.Rows(2)("YMember") = 147.0
matTable.Rows(3)("YMember") = 69.0

Me.PieChart1.DataSource = matTable
Me.PieChart1.DataBind()

End Sub

C#：
private void TestChart2_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 <= 4; i += 1)
{
DataRow row = matTable.NewRow();
matTable.Rows.Add(row);
}

matTable.Rows[0]["XMember"] = "餐饮";
matTable.Rows[1]["XMember"] = "住宿";
matTable.Rows[2]["XMember"] = "长途";
matTable.Rows[3]["XMember"] = "通讯";

matTable.Rows[0]["YMember"] = 740.0;
matTable.Rows[1]["YMember"] = 280.0;
matTable.Rows[2]["YMember"] = 147.0;
matTable.Rows[3]["YMember"] = 69.0;

this.PieChart1.DataSource = matTable;
this.PieChart1.DataBind();
}

d.XAxisLabelMember属性

e.YAxisLabelMember属性
