定制蜡烛图

以下是定制蜡烛图示例。我们已在 “Google 图表配置语法”一章中看到用于绘制此图表的配置。现在，我们来看一下整个示例。

配置

我们已使用 **candlestick** 配置来定制日历。

// 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
   }
};
