WPF 圖表控制項 MetroChart

Torsten Mandelkow MetroChart包括以下：

• ColumnChart（ClusteredColumnChart，StackedColumnChart，StackedColumnChart100Percent）
• 餅圖（餅圖和Dognut）
• BarChart（ClusteredBarChart，StackedBarChart，StackedBarChart100Percent）
• 甜甜圈圖
• 徑向測量圖

有相當大的演示可以從CodePlex下載，但是不夠詳細的，所以我決定寫一個小的入門指南。作為文檔的一部分，還有一個操作方法，但它並沒有真正起作用。圖表沒有渲染，我一步一步地遵循瞭如何操作，

其中

• ChartTitle是圖表的主要標題
• ChartSubTitle是字幕，當然以較小的字體顯示
• DisplayMember是保存該值名稱的屬性的名稱
• ValueMember是保存該值的屬性的名稱
• ItemsSource是本系列產品的來源。
• SeriesTitle擁有特定系列的標題
