Highcharts data representation (3) and highcharts Data Representation
Highcharts data representation (3) uses an array of objects to specify the value of each item on the node. However, when many nodes exist, a large amount of redundant code is generated. If the configuration item name is not specified, the object array can simplify the two-dimensional array. The format is as follows:

• Data :[
• [Number | String, Number, Color, Number | String | Object],
• [Number | String, Number, Color, Number | String | Object],
• [Number | String, Number, Color, Number | String | Object],
• ......,
• [Number | String, Number, Color, Number | String | Object],
• ]

At this time, you can save a lot of code writing. However, because different data columns may contain different projects, Highcharts must be able to correctly identify the order of each project. In this case, you can use the config map keys to specify the project order. This configuration item is a sub-configuration item of series. The syntax is as follows:

• Keys: Array <String>

The parameter Array <String> specifies the configuration item name corresponding to each value in the two-dimensional Array. For the example just now, you need to use keys to specify the form as follows:

• Keys: ['x', 'y', 'color', 'hightemtime']
