主要介绍了DevExpress之ChartControl用法实例总结,需要的朋友可以参考下

DevExpress中的ChartControl顾名思义就是数据基于图表展示，其关键在于Series上的处理。本文实例展示了ChartControl的用法，具体内容如下：

主要功能代码部分如下：

using System;

using System.Drawing;

using DevExpress.XtraCharts;

namespace DevExpressUtilHelpV3

/// <param name="chat">ChartControl</param>

/// <param name="seriesName">Series名字『诸如：理论电量』</param>

/// <param name="seriesType">seriesType『枚举』</param>

/// <param name="dataSource">数据源</param>

/// <param name="xBindName">ChartControl的X轴绑定</param>

/// <param name="yBindName">ChartControl的Y轴绑定</param>

public static void CreateSeries(this ChartControl chat, string seriesName, ViewType seriesType, object dataSource, string xBindName, string yBindName)

{

CreateSeries(chat, seriesName, seriesType, dataSource, xBindName, yBindName, null);

}

/// <param name="dataSource">数据源</param>

/// <param name="xBindName">ChartControl的X轴绑定</param>

/// <param name="yBindName">ChartControl的Y轴绑定</param>

/// <param name="createSeriesRule">Series自定义『委托』</param>

public static void CreateSeries(this ChartControl chat, string seriesName, ViewType seriesType, object dataSource, string xBindName, string yBindName, Action<Series> createSeriesRule)

{

if (chat == null)

throw new ArgumentNullException("chat");

if (string.IsNullOrEmpty(seriesName))

throw new ArgumentNullException("seriesType");

_series.ArgumentDataMember = xBindName;

_series.ValueDataMembers[0] = yBindName;

_series.DataSource = dataSource;

if (createSeriesRule != null)

createSeriesRule(_series);

chat.Series.Add(_series);

}

}

}

代码使用示例如下：

DataTable _dt = CreateTestDB();

chartControl1.CreateSeries("理论功率", ViewType.Spline, _dt, "time", "Power");

chartControl1.CreateSeries("实际功率", ViewType.Spline, _dt, "time", "ActulPower");

}

/// <summary>

/// 准备数据源

/// </summary>

/// <returns>DataTable</returns>

private DataTable CreateTestDB()

{

{

DataRow _drNew = _testData.NewRow();

_drNew["time"] = string.Format("{0}点", i);

_drNew["Power"] = 250;

_drNew["ActulPower"] = _rm.Next(220, 245);

_testData.Rows.Add(_drNew);

}

return _testData;

}
