Difference value start month and final month...COVID 19

[alexandernatale]

 Hello!

I have a problem.
I have a data table of Covid19. In this table i have 
| Date | Region | Recovered | Death | Hospitalized | ecc..
The values of the patients are cumulative: for each day I have the total value but no the incremetal value for day.

My goal it's calculate the month trend --> for example for May I would like to calculate the difference of recovered at the end of the month and at the beginning of the month to understand the monthly increase.

I also have the data table I have a master calendar table.

I would like to realize a histogram o another chart..

Suggest? 

@Michael_Tarallo please help me 😓

Hello Alexandra,

May I suggest that you add some dummy data to your question.  And then show us a chart of what you expect the data to look like?  It makes people want to help you because the objective is clearly shown.

To complete the discussion, the problem can also be seen in this other way: Having an initial warehouse with inventory at the beginning of the month and one at the end of the month, I want to evaluate the increase / decrease of inventories in the warehouse considering therefore the initial inventory on day 1 of the month and the final inventory on day 31 of the same month. This calculation, for all months
