Installation

Like any other Highcharts module (e.g. exporting), add <script> tag pointing to annotations.js below Highcharts script tag.

For NPM users:

var Highcharts = require('highcharts'),
    HighchartsAnnotations = require('annotations')(Highcharts);

For BOWER users:

	bower install highcharts-annotations

Sample code

new Highcharts.Chart({
  chart: {
    renderTo: container
  },
  series: [{
      data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0]
  }],
  annotations: [{
    xValue: 4,
    yValue: 125,
    title: {
        text: "Annotated chart!"
    }
  }]
})
