Line Chart Data Structure Description¶

// Below is a demo data for a line chart (two lines)
  {
    series: [
      {
        values: [
          [1737344820000, 1.33635905],
          [1737344810000, 2.6481715],
          [1737344800000, 1.21059269],
        ],
        columns: ['time', 'avg(usage_system)'],
      },
      {
        values: [
          [1737344820000, 1.79202423],
          [1737344810000, 0.83102493],
          [1737344800000, 1.84110971],
        ],
        columns: ['time', 'avg(usage_system)'],
      },
    ],
  },

Field Description:

Parameter	Type	Required	Description
series	list	Yes	Data groups, the length indicates how many groups of data (in a line chart, how many lines)
series[#]	dict		A set of data
series[#].columns	list	Yes	List of data source field keys, ['time', ...]
series[#].columns[#]	str		Data source field key, the first column must be 'time'
series[#].values	list	Yes	Two-dimensional array, each item represents a data point
series[#].values[#]	list		Data source consisting of `[timestamp, value]`; in a line chart, the length of values is 2, each data point represents a connection point on the line chart
