Switching x-axes from horizontal secondary to primary

[Amethy]

Hello! I have a chart with 4 axes (i.e. horizontal primary, horizontal secondary, vertical primary and vertical secondary).

I'm using Excel 2016 and need to switch the horizontal secondary axis at the top (date) with the horizontal primary axis at the bottom (number). Unfortunately, I cannot switch the datatable to switch the horinzontal axes.

Any suggestion is appreciated! Thank you!
