Need dynamic x axis in waterfall chart - x axis scale using measure

Hello, need help in understanding the workaround for having a dynamic x axis in my waterfall chart. I am displaying Market Share (y-axis) vs Evol (vs YA) (x-axis) using the waterfall chart across multiple countries and categories. Now, for Evol (vs YA), I need the x axis to take origin as a category value for a particular country. How do i enable this? Essentially, from my understanding it looks like we need to put a measure in the scale tab in format pane? Is that possible?
