I don't know if a given value is increasing or decreasing in total value for that value every month.  
I would like to illustrate that this is the case.  
I'm thinking of realizing this using Timelion, but I'm troubled, and I'm not sure how to use it.  
I would like some advice.

Is it possible to aggregate periods in Timelion?

One. Sum value in one month  
Two. Get the difference of time series  
Three. Calculation of change for difference
