在這個(gè)例子中我們將使用DevExpress控件XtraChart來(lái)演示如何在運(yùn)行時(shí)為圖表添加和修改標(biāo)題。

C#

// Create chart titles.
ChartTitle chartTitle1 = new ChartTitle();
ChartTitle chartTitle2 = new ChartTitle();

// Define the text for the titles.
chartTitle1.Text = "<i>Basic</i> <b>HTML</b> <u>is</u> <color=blue>supported</color>.";
chartTitle2.Text = "The capability to word-wrap is available for chart titles.";

chartTitle2.WordWrap = true;
chartTitle2.MaxLineCount = 2;

// Define the alignment of the titles.
chartTitle1.Alignment = StringAlignment.Center;
chartTitle2.Alignment = StringAlignment.Near;

// Place the titles where it's required.
chartTitle1.Dock = ChartTitleDockStyle.Top;
chartTitle2.Dock = ChartTitleDockStyle.Bottom;

// Customize a title's appearance.
chartTitle1.Antialiasing = true;
chartTitle1.Font = new Font("Tahoma", 14, FontStyle.Bold);
chartTitle1.TextColor = Color.Red;
chartTitle1.Indent = 10;

// Add the titles to the chart.
chartControl1.Titles.AddRange(new ChartTitle[] {
chartTitle1,
chartTitle2});

VB

' Create chart titles.
Dim chartTitle1 As New ChartTitle()
Dim chartTitle2 As New ChartTitle()

' Define the text for the titles.
chartTitle1.Text = "<i>Basic</i> <b>HTML</b> <u>is</u> <color=blue>supported</color>."
chartTitle2.Text = "The capability to word-wrap is available for chart titles."

chartTitle2.WordWrap = True
chartTitle2.MaxLineCount = 2

' Define the alignment of the titles.
chartTitle1.Alignment = StringAlignment.Center
chartTitle2.Alignment = StringAlignment.Near

' Place the titles where it's required.
chartTitle1.Dock = ChartTitleDockStyle.Top
chartTitle2.Dock = ChartTitleDockStyle.Bottom

' Customize a title's appearance.
chartTitle1.Antialiasing = True
chartTitle1.Font = New Font("Tahoma", 14, FontStyle.Bold)
chartTitle1.TextColor = Color.Red
chartTitle1.Indent = 10

' Add the titles to the chart.
chartControl1.Titles.AddRange(New ChartTitle() { chartTitle1, chartTitle2})
