I am currently working on a 2x2 subplot figure. In each subplot, I have 3 groups on the X axis. I want to decrease the spacing between each of these groups on the X-axis. Currently, the last value on 221 subplot is very close to the first value of 222 subplot.
I have changed the spacing between subplots but I would like each of the subplots to be more compact by decreasing the spacing between the X-axis values. The variable on the X-axis is non-numeric.
