1、数据

这边提供一个go的demo

package main

import (
    "math/rand"
    "net/http"
    "time"

    "github.com/gin-gonic/gin"
)

func main() {
    router := gin.Default()

    rand.Seed(time.Now().Unix())
    router.GET("/api/data", func(ctx *gin.Context) {
        var data []Metric
        for i := 0; i < 10; i++ {
            data = append(data, Metric{Entity: "m1", Value: rand.Float64() * 10.0, Time: time.Now().Add(time.Duration(-i) * time.Minute).UnixMilli()})
            data = append(data, Metric{Entity: "m2", Value: rand.Float64() * 10.0, Time: time.Now().Add(time.Duration(-i) * time.Minute).UnixMilli()})
            data = append(data, Metric{Entity: "m3", Value: rand.Float64() * 10.0, Time: time.Now().Add(time.Duration(-i) * time.Minute).UnixMilli()})
        }

        ctx.JSON(http.StatusOK, data)
    })

    router.Run(":8080")
}

type Metric struct {
    Entity string      `json:"entity"`
    Value  interface{} `json:"value"`
    Time   int64       `json:"time"`
}

2、图表
