How to use column and bucket charts to display data in Highcharts

The column and bucket chart is a commonly used data visualization chart type in Highcharts, which can be displayed intuitively Different categories of data and compare their sizes. This article will introduce how to use Highcharts to create a column and bucket chart, and provide detailed code examples.

First, we need to introduce the Highcharts library and related dependency files. Library files can be downloaded from the official website of Highcharts (www.highcharts.com) and introduced into HTML files. We also need to introduce JQuery because the Highcharts library depends on JQuery.

Next, we need to create an HTML container to display the column and bucket chart. You can use a div element and give it a unique id attribute, as shown below:

<div id="container"></div>

Then, we need to prepare the data to display in the column and bucket chart. Data can be static or dynamically obtained from the server. Here we assume that we have the following data:

var data = [
  { name: 'A', value: 10 },
  { name: 'B', value: 20 },
  { name: 'C', value: 15 },
  { name: 'D', value: 25 }
];

Next, we can use Highcharts to create a column and bucket chart. First, we need to define the configuration options of the chart, including chart type, title, X-axis and Y-axis labels, etc. We then need to pass the data to the chart and create the chart with the chart configuration options as parameters. The specific code is as follows:

$(function() {
  Highcharts.chart('container', {
    chart: {
      type: 'column'
    },
    title: {
      text: '柱桶图'
    },
    xAxis: {
      categories: data.map(function(item) {
        return item.name;
      })
    },
    yAxis: {
      title: {
        text: '数值'
      }
    },
    series: [{
      name: '数值',
      data: data.map(function(item) {
        return item.value;
      })
    }]
  });
});

In the above code, we use the chart method of Highcharts to create a column and bucket chart. Among them, the chart attribute specifies the type of chart as column (column chart), the title attribute specifies the title of the chart as "column and bucket chart", the xAxis attribute specifies the label of the X-axis as the name attribute in the data, and the yAxis attribute specifies the label of the Y-axis as "numeric value". The series attribute specifies the data series of the chart, where the name attribute specifies the name of the data series as "value", and the data attribute specifies the specific value of the data series as the value attribute in the data.

Finally, we set the first parameter of the Highcharts.chart method to the id of the previously created HTML container to render the chart into the container.

After completing the above steps, we can run the code in the browser and see a column and bucket chart in the HTML container to display data.
