Use SWITCH to change the column in charts with a Slicer

Hello everyone, 

I'm looking to create a slicer that enable me to change the column name in a table or a chart, I don't know if its possible :

So,  instead of having a flexible "sales " results (like its usually done) , we create a flexible "colums name" that reallocate the amount of sales depending the columns criteria thats chosen.

For example : 

In this case, if we choose "Customer" , it shows the sales by customer. If we choose "Region", it shows the sales by Region ...

Hope someone can help me .... 

Thanks
