如何以编程方式放大highcharts？ [英] How to programmatically zoom in highcharts?

问题描述

调用axis.setExtremes（）或axis.zoom（）时，关联的缩放按钮不会突出显示。

例如，

有没有简单的方法来完成这个？

对于更多的上下文：我想做我的应用程序，所以如果你查看一个图形，缩放，然后离开图表，并再回到它，我想恢复你的'缩放级别'。

我基本上是通过监听afterSetExtremes并存储最大/最小值，然后在图上调用'zoom'用户返回。

如果有一个更简单的方法来完成这个，我会很好。

解决方案

您也可以在按钮上调用setState。

  chart.rangeSelector.buttons [3] .setState（2）; 
  

When calling axis.setExtremes() or axis.zoom(), the associated zoom button does not become highlighted.

For example, if I programatically 'zoom' to 1-hour, I would like the '1 hour' zoom button to appear as 'pressed'.

Is there a simple way to accomplish this?

For more context: I want to make my app stately, so that if you view a graph, zoom, then navigate away from the graph and back to it again, I want to restore your 'zoom level'.

I have this basically working by listening for afterSetExtremes and storing the max/min values, and then using those to call 'zoom' on the graph when the user returns.

If there is a simpler way to accomplish this, I'd be fine with that.

Thanks for any direction!

解决方案

You can also call setState on the button.

chart.rangeSelector.buttons[3].setState(2);
