Manipulating Text in Chart Elements

Hi Team,

I'm having trouble finding where to change the justification of category labels in the newest version of Excel. Some labels appear centered, others appear right justified. I can't seem to find how to change it. Seems like I also used to be able to change the size of the text box holding all those labels so that I could stretch the bars wider and have data labels actually legible. I can't find how to change that either. Any help would be appreciated!
