KQL在单个图形中绘制几个不同时期的平均值

Question

能否在一张图中画出几个不同周期的平均值？

我有类似蓝色图表的东西。我需要添加黑色和红色图表之类的东西。

我的示例数据集是：

let dt = datatable (dt:datetime, val:int)
[
     '2022-04-18T03:20:39.956Z' ,3
    ,'2022-04-18T03:55:22.471Z' ,-1
    ,'2022-04-18T04:02:40.761Z' ,-4
    ,'2022-04-18T04:10:41.68Z'  ,-5

];
dt 
| make-series avg(val), min(val), max(val) on dt step 1h
| render timechart

看起来样本数据集太大了，我必须在这里添加一些文本）

Answer 1

是的，有可能。
还要检查数据样本的生成。

// Generation of a data sample. Not part of the solution.
let t = materialize(range i from 1 to 300 step 1 | project dt = ago(365d*50*rand()), val = -100 + toint(200*rand()));
// The solution starts here.
union
     (t | summarize avg(val) by dt = startofmonth(dt)                      | extend type = "Monthly")
    ,(t | summarize avg(val) by dt = startofyear(dt)                       | extend type = "Annual")
    ,(t | summarize avg(val) by dt = make_datetime(bin(getyear(dt),5),1,1) | extend type = "5 Year")
| render timechart
