定製蠟燭圖

以下是定製蠟燭圖示例。我們已在 “Google 圖表配置語法”一章中看到用於繪製此圖表的配置。現在，我們來看一下整個示例。

配置

我們已使用 **candlestick** 配置來定製日曆。

// Set chart options
var options = {
   legend: 'none',
   bar: { groupWidth: '100%' },     // Remove space between bars.
   candlestick: {
      fallingColor: { strokeWidth: 0, fill: '#a52714' }, // red
      risingColor: { strokeWidth: 0, fill: '#0f9d58' }   // green
   }
};
