MindFusion Charting可以快速帮助开发人员创建数据图表显示应用程序，支持bar, line, area, scatter, bubble, pie, doughnut, radar and polar等图表类型，支持多轴显示，自定义图表外观，自定义轴标签和文本格式化，对于图例控件也是提供了丰富的API，下面主要就图例的设置进行简单的介绍：

对于图例控件主要提供了以下属性进行控制：

• LegendAlignment：图例的对齐方式
• LegendBackgroundBrush：主要用于设置背景色
• LegendBorder：设置图例的边框
• LegendBorderMargin：设置边框的边距
• LegendBrush：文本的颜色
• LegendColumns：设置图例的列数
• LegendFont：图例文本的字体
• LegendGridType：图例表格的类型
• LegendLabels：图例的标签
• LegendOffset：图例的偏移距离
• LegendPen
• LegendPosition：设置图例的位置
• LegendWordWrap：设置图例文本是否换行

具体可以查看下面的事例：
