How to create interactive data visualizations with Highcharts

<div id="container" style="width: 600px; height: 400px;"></div>

where container is the unique identifier of the chart container, which you can customize.

3. Draw basic charts
Next, we start using Highcharts to create interactive data visualization charts.
First, create an empty Highcharts chart object and specify the container and basic configuration options. For example:

Highcharts.chart('container', {
    chart: {
        type: 'bar'  //指定图表类型为柱状图
    },
    title: {
        text: '销售数据'  //设置图表标题
    },
    xAxis: {
        categories: ['一月', '二月', '三月', '四月', '五月']  //设置x轴刻度标签
    },
    yAxis: {
        title: {
            text: '销售额'  //设置y轴标题
        }
    },
    series: [{
        name: '销售额',  //设置数据系列名称
        data: [100, 200, 150, 300, 250]  //设置数据系列的数据
    }]
});

The above code creates a histogram, with the x-axis representing the month and the y-axis representing the sales, visually displaying the sales in different months.

4. Configuring data series and interactive functions
In addition to basic chart configuration, Highcharts also provides a wealth of configuration options that can be set according to actual needs.

1. Configuring data series
   Highcharts supports multiple data series, and can configure attributes such as styles and labels for each data series. For example:

   series: [{
    name: '销售额',
    data: [100, 200, 150, 300, 250],
    color: '#ff9900'  //设置数据系列的颜色
   }, {
    name: '利润',
    data: [80, 150, 120, 200, 180],
    color: '#66cc00'
   }]

   Copy after login

   The above code creates two data series, representing sales and profits respectively, and assigns colors to each data series.

2. Add interactive functions
   Highcharts supports a variety of interactive functions, including mouse hover, click events, smooth animation, etc. The following is an example of adding mouse hover prompts and click events:

   tooltip: {
    shared: true  //启用鼠标悬停提示共享
   },
   plotOptions: {
    series: {
        cursor: 'pointer',
        point: {
            events: {
                click: function () {
                    alert('你点击了 ' + this.category + ' 月的数据');  //点击事件处理函数
                }
            }
        }
    }
   }

   Copy after login

   The above code designs mouse hover prompts and click events. When the mouse hovers over a data point, the specific information of the data point will be displayed. Value; when a data point is clicked, a prompt box will pop up to display the clicked month.

   5. Further customization
   In addition to the above basic settings and interactive functions, Highcharts also provides many other customization options, such as modifying the chart style and setting the coordinate axis range. , add legends, etc. When creating a chart, you can further customize the chart's appearance and behavior based on your needs.
