javascript - Highcharts 如何保存选定的图例

Question

我正在尝试是否可以从 highcharts 获得回调来说明已选择或取消选择哪个图例项目。然后我可以将其添加到保存的系列数据中，因此当我再次加载 Highcharts 时，它具有保存的选定图例。

Answer 1

查看series.events.legendItemClick ,

legendItemClick: function

Fires when the legend item belonging to the series is clicked. One parameter, event, is passed to the function. The default action is to toggle the visibility of the series. This can be prevented by returning false or calling event.preventDefault().

或series.events.hide当系列被隐藏时会被调用。

hide: function

Fires when the series is hidden after chart generation time, either by clicking the legend item or by calling .hide().

将其中之一与 series.visible 结合使用你应该能够做你想做的事。

visible: Boolean

Set the initial visibility of the series.

Defaults to true.
