Assuming you have the measures available, what you need can be implemented by using Field Parameters.

So, without knowing anything else about your data model, I will suggest the most basic approach:

• Create a Field Parameter (FP) with the Week  and the Month from your Calendar Table. Check the Add Slicer option to have the slicer generated.
• Create a measure that returns WoW values when Weeks are selected and MoM values when Months are selected. It might be tricky to get the selected value on a Field Parameter, so maybe you can use ISINSCOPE() for that.
• in your visual, put FP in the X-Axis and the measure in the Y-Axis (or Value?) slot.

Now, the visual will display content according to your selection on the Field Parameter,
