How to add custom label to x and y axis

I need to add the line “volume of base” to the x and y axis of my graph. How do I do this? I’ve been messing around for the last 30 minutes and could not figure it out. Please help.

Double click your chart > you will a grey frame with 6 black squares

Right click in the area outside the wall > select Insert titles > enter your description for the axis you need > OK

I recommend you to also look into the guides, which you can download free of charge from: https://wiki.documentfoundation.org/Documentation/Publications
