Data labels on X-asis

Hello, 

I'm creating a power bi dashbaord for sales but I'm beginner. I don't why but I ve create a sales chart by weeks. Unfortunately my data labels on my X-asis displays 5 to 5 and not one to one. So I ve my 52 weeks but my in the X-Asis I ve only write 5-10-15 etc.... 

Someone knows how to resolve it`?

Thanks in advance,
