1、柱状图上显示数值

?

//第一种方法

this.UltraChartSScore.Data.ZeroAligned = true;

this.UltraChartSScore.DataSource = dt.DefaultView;

this.UltraChartSScore.DataBind();

ChartTextAppearance text = new ChartTextAppearance();

text.Column = -2;

text.Row = -2;

text.PositionFromRadius = 50;

text.VerticalAlign = System.Drawing.StringAlignment.Far;

text.ItemFormatString = "<DATA_VALUE:00.00>";

text.Visible = true;

UltraChartSScore.ColumnChart.ChartText.Add(text);

this.UltraChartSScore.TitleTop.Text = "主项S得分对比柱状图";

//第二种方法（一个一个的添加）

for (int i = 0; i < dt.Rows.Count; i++)

{

    for (int j = 0; j < 4; j++)

    {

        ChartTextAppearance text = new ChartTextAppearance();

        text.Row = i;

        text.Column = j;

        text.VerticalAlign = System.Drawing.StringAlignment.Far;

        text.ItemFormatString = "<DATA_VALUE:00.00>";

        text.Visible = true;

        chart.ColumnChart.ChartText.Add(text);

    }

}
