When we use multiple dimension is it possible to not show one of the dimension's title?

[Lucius_Artorius_Castus]

Is it possible to hide the category title from x axis?

or possible to remove the comma between two dimension?

It's not possible. 
A workaround is to use a variable input control to change the value of a variable, and use it to make a dynamic dimension. Not ideal but like this users cannot create weird combinations.
