Google 图表 - 基本蜡烛图

以下是基本蜡烛图的示例。蜡烛图通常用于显示收盘价和开盘价，它们叠加在总方差之上。蜡烛图经常用来显示股票的价值行为。此图表中，对于开盘价低于收盘价（收益）的项目，绘有填充的框；对于开盘价高于收盘价（亏损）的项目，绘有空心框。我们已经在Google 图表配置语法一章中了解了用来绘制此图表的配置。下面让我们来看看完整的示例。

配置

我们使用 CandlestickChart 类来显示基于蜡烛的图表。

//candlestick chart
var chart = new google.visualization.CandlestickChart
(document.getElementById('container'));
