Power Bi Report Builder. Problem with Graph dates

[Gigh3n]

Hi all,

i need help and many thanks in advance.

In power bi report builder i have imported correctly the data set.

So wen i try to create the istogram or other graph not all the date are imported in the graph.

For example:

I have this dataset: 

Date	Num of intervents
23/01/2020 10:30:00	10
23/02/2020 11:30:00	20
23/03/2020 11:30:00	30
23/04/2020 11:30:00	40
23/05/2020 11:30:00	40
........	....

when i created the graph, in my graph not are reported correctly all the date ma only a some month.

for example: 

despite having the data in the dataset, in this case the month of April is not reported

have you any suggest for me?

thanks in advance
