Dear all, I have a box-plot of seasonal precipitation as attached below. As you can see in Central region there is a group of five different datasets with five different colors. I need to put x-tick label exactly at the center of these box-plots on x-axis. Right now the x-tick is marked on the last box, i.e., below the black box. Let me know how I can place my ticks exactly at the center of these boxes, so that it represents these sets of five boxes correspond to one region.
