The heat map is a visual data display method that can represent each area through different color shades the data distribution. In the field of data visualization, Highcharts is a very popular JavaScript library that provides rich chart types and interactive functions.
This article will introduce how to use Highcharts to create a map heat map and provide specific code examples.
First, we need to prepare some data. Suppose we have a dataset containing different cities and corresponding populations. The data format is similar to:
1 2 3 4 5 6 |
|
Next, we will create a blank HTML page and add a reference to Highcharts. You can download the Highcharts library file and introduce it into the HTML page, or you can use the online reference method. Add the following code to the HTML page:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
|
Note that in this example we introduced the map module of Highcharts and the data of the China map.
Next, we need to write the logic for drawing the map heat map in JavaScript code. Add the following code to the path/to/your/script.js file:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
|
In this code, we use the Highcharts.mapChart function to create a map chart and set the chart's value through the passed configuration object Title, subtitle, data, etc.
Finally, we only need to open the HTML page in the browser to see the drawn map heat map.
To summarize, the steps to create a map heat map using Highcharts are as follows:
- Prepare the data.
- Create an HTML page and introduce the Highcharts library file.
- Write JavaScript code to draw the map heat map.
- Open the HTML page in the browser to view the results.
