highcharts series 不在图例中展示

如果您希望 Highcharts 的某个系列（series）不在图例（legend）中展示，可以在 Highcharts 配置中设置 `showInLegend` 选项为 `false`。例如：

series: [{
    name: 'Series 1',
    data: [1, 2, 3],
    showInLegend: false // 不展示在图例中
}, {
    name: 'Series 2',
    data: [4, 5, 6]
}]

在上面的代码中，`Series 1` 不会展示在图例中，而 `Series 2` 会展示在图例中。

highcharts series

Highcharts series is a configuration option that allows you to specify the data points to be plotted on a chart. It defines the individual data series that make up the chart. Each series can include multiple data points with x and y values, or other relevant properties depending on the chart type.

For example, in line charts, each series represents a line connecting the data points. In bar charts, each series represents a set of bars grouped together. In pie charts, each series represents a slice of the pie.

The series configuration can be defined as an array of objects, where each object represents a series. Each series object can have properties like name, data, type, color, etc., which define its appearance and data.

Here's an example of a simple line chart with two series:

Highcharts.chart('container', {
    series: [
        {
            name: 'Series 1',
            data: [1, 2, 3, 4, 5],
            type: 'line'
        },
        {
            name: 'Series 2',
            data: [3, 4, 2, 1, 5],
            type: 'line'
        }
    ]
});

In this example, we have two line series named 'Series 1' and 'Series 2'. Each series has its own set of data points defined by the `data` property. They are plotted as lines on the chart.

highcharts 点击图例改变图例题目

可以通过 Highcharts 提供的 `legendItemClick` 事件来实现点击图例改变图例标题。具体实现步骤如下：

1. 在 `legend` 配置项中，设置 `itemEvents` 为 `['click']`，开启图例点击事件。

2. 在 `plotOptions` 配置项中，为相应的图表类型（如 `line`、`column` 等）设置 `events.legendItemClick` 属性，指定图例点击事件的回调函数。

3. 在回调函数中，通过 `this.name` 获取当前点击的图例名称，并使用 `chart.setTitle` 方法修改图表标题。

示例代码如下：

Highcharts.chart('container', {
  // 其他配置项
  legend: {
    itemEvents: ['click']
  },
  plotOptions: {
    line: {
      events: {
        legendItemClick: function() {
          var chart = this.chart;
          var title = chart.title.textStr;
          var name = this.name;
          chart.setTitle({ text: title + ' - ' + name });
        }
      }
    }
  },
  // 其他配置项
});

在以上代码中，我们为 `line` 图表类型设置了图例点击事件的回调函数。当用户点击某个图例时，回调函数会在当前 `chart` 对象的基础上获取当前图表的标题 `title`，并将当前点击的图例名称 `name` 拼接在标题后面，最后使用 `chart.setTitle` 方法更新图表标题。
