How do I count rows that consist of dates into a line graph? And possible even make a forecast?

[Anonymous]

I would like to have the start date (the amount of the same dates, counting) in a line graph as well as the recent start date (the amcount of the same dates, counting)

For example, in the line graph I would like to have all the dates that relate tot september 2020 in one point of the graph, as well as the other months. Do I make an index column to give the rows a number in order to make the graph? How do I make this graph? 

Note: I am new to Power BI and English is not my first language. Thank you in advance.

Hi @Anonymous ,

Is this what you want?

You can create a calendar table and two measures, and drag the appropriate fields into the line chart.

Calendar table:

Realtionships:

Measures:

Count of start date = 
COUNT('Table'[Start Date]) + 0

Count of recent start date = 
CALCULATE(COUNT('Table'[Recent Start Date]),USERELATIONSHIP('Table'[Recent Start Date],'Calendar'[Date])) + 0
