Google圖表 - 自定義日曆圖

以下是自定義日曆圖的示例。日曆圖用於以時間段為基礎視覺化資料。我們已經看過在 Google 圖表配置語法章節中用於繪製此圖的配置。所以，我們來看一個完整的示例。

配置

我們使用了 **calendar** 配置來定製日曆。

// Set chart options
var options = {
   calendar: {
      yearLabel: {
         fontName: 'Times-Roman',
         fontSize: 32,
         color: '#1A8763',
         bold: true,
         italic: true
      },
      
      monthOutlineColor: {
         stroke: '#981b48',
         strokeOpacity: 0.8,
         strokeWidth: 2
      },
      
      unusedMonthOutlineColor: {
         stroke: '#bc5679',
         strokeOpacity: 0.8,
         strokeWidth: 1
      }		 
   }
};
