Hi @Gent_Zhubi !
It sounds like you’re asking for two different levels of aggregation on single time line. Unfortunately, that’s not available. You’ll notice that you can customize the time aggregation by year, quarter, month, week, day, hour, minute or second, but only one at a time.
However, I believe that a drill down can achieve what you’re looking for. You’d start with the yearly aggregate and then have your users right click to see the data by month. You can see how to implement this here. There’s also an exercise in a workshop that you use here. And this post talks specifically about the date drill down, here.
Hope that helps!!
