Enhancement - Remove X-axis for value chain mapping only

[PaulComis]

I have a handful of maps where I want to start with just the value chain (i.e. no evolution axis)...at least to begin with.

Would it be possible to have a switch that turns off the X-axis (and the vertical dividers).

I can remove the x-axis labels with "evolution -", but its not entirely satisfactory.

Thanks in advance!
