DevExpress之饼状图突出（Explode）设置实例

本文实例讲述了devexpress之饼状图突出（explode）设置方法，分享给大家供大家参考。具体实现方法如下：

关键代码如下：

/// <summary>
/// 饼状图突出设置
/// </summary>
/// <param name="chart">chartcontrol</param>
/// <param name="pieseries">series【仅仅适用于pieseriesview】</param>
/// <param name="explodemode">突出模式【枚举】</param>
/// <param name="explodedvalue">突出间距</param>
/// <param name="dragpie">是否可以拖动突出饼状</param>
public static void setpieexplode(this chartcontrol chart, series pieseries, pieexplodemode explodemode, int explodedvalue, bool dragpie)
{
    if (pieseries.view is pieseriesview)
    {
 //bool _hittesting = chart.runtimehittesting;
 if (!chart.runtimehittesting)
     chart.runtimehittesting = true;

 pieseriesview _pieview = pieseries.view as pieseriesview;
 _pieview.explodemode = explodemode;
 _pieview.explodeddistancepercentage = explodedvalue;
 _pieview.runtimeexploding = dragpie;

 // chart.runtimehittesting = _hittesting;
    }
}

代码使用：

private void builderdevchart()
{
    series _pieseries = new series("series 1", viewtype.pie);
    _pieseries.valuedatamembers[0] = "value";
    _pieseries.argumentdatamember = "name";
    _pieseries.datasource = createchartdata();
    chartcontrol1.series.add(_pieseries);
    //----------------------------------------
    _pieseries.legendpointoptions.pointview = pointview.argumentandvalues;
    _pieseries.setpiepercentage(numericformat.percent, pointview.argumentandvalues);
    chartcontrol1.setaxisxtitle("test", color.red);
    _pieseries.setlableposition(pieserieslabelposition.twocolumns);
    chartcontrol1.setpieexplode(_pieseries, pieexplodemode.minvalue, 5, true);
}

运行效果如下图所示：
