Courtney, do you mean how to increase the font size? Richt-click the axis to
format it, choose font and the rest is automatic I presume. You may wish to
untick AutoScale so the font size remains the same with resizing your chart,
if relevant.

Help! I can't resize an axis title on my computer. I can do so in the same

do I have to change?
