Cannot Display a Bar Chart with Only One Axis

I have several nominal values in the X-axis, and a numeric/linear values in the Y-axis. Example: Selection_034

However, the option to display the result as a bar chart is greyed out:

This is a similar issue to #925. I discovered that I could still select the bar chart option despite it being greyed out. But still, I can’t get Metabase to display the chart like how I wanted:

Any help?

@sagungrp Just return a fake X-column: SELECT ... , "X" AS 'X' FROM ...

Works like a charm, thanks!
