The idea is to have a large historical down-to-the-minute chart (with millions of data points) which is at the same time updated in real time (if the user scrolls to the right edge).

官网使用教程官网API文档可配置选项在了解可配置选项前，我们一定要知道图表都是有哪些部分组成。一般情况下，Highcharts 包含标题（Title）、坐标轴（Axis）、数据列（Series）、数据提示框（Tooltip）、图例（Legend）、版权标签（Credits）等，另外还可以包括导出功能按钮（Exporting）、标示线（PlotLines）、标示区域（PlotBands）、数据标签（dataLabels）等。 Highcharts 基本组成部分如下图所示: 1. 标题（Title）图表标题，包含标题和副标题（subTitle），其中副标题是非必须的。 2. 坐标轴（Axis）坐标轴包含x轴（xAxis）和y轴（yAxis）。通常情况下，x轴显示在图表的底部，y轴显示在图表的左侧。多个数据列可以共同使用同一个坐标轴，为了对比或区分数据，Highcharts提供了多轴的支持。 3. 数据列（Series）数据列即图表上一个或多个数据系列，比如曲线图中的一条曲线，柱状图中的一个柱形。 4. 数据提示框（Tooltip）当鼠标悬停在某点上时，以框的形式提示该点的数据，比如该点的值、数据单位等。数据提示框内提示的信息完全可以通过格式化函数动态指定。 5. 图例（Legend）图例是图表中用不同形状、颜色
