Is it possible to change the width of the bars in a bar chart?
I have been looking at LookML parameters to change in the LookML dashboard, but could not find any.
Our (stacked) bar chart currently looks like this:

Thanks in advance!
Use Spacing and Inner Spacing settings of the visualisation
This is 0.6
Vs 0.9
