Relative date slicer intuitive data points

Hi all,

I have a report in which there is a date slicer, a relative date option and 2 visuals. The slicers do their job perfectly to filter the date in the visuals, however the data points in the visuals stay on "weekly" even though I select "Last 4 months" in the relative date option. This could be because in the visuals my X-Axis is "week start date", however after trying it with multiple available date options, I can't get it to work intuitively. 

So to sum it up -> I want the data points in the visuals to be weekly when I select "Weeks" in the relative date & monthly data points when I select "Months" in the relative data. I just have no clue how I can get this to work since the Interaction filters correctly. 

Anyone that knows how (and if) I can arrange this?

Thanks in advance! 🙂
