There are two ways to reposition the various texts on your graph. The techniques described here apply to any text—axis labels, grid labels, captions, annotations, etc.
Left Click and Drag
Position the mouse cursor over the text you want to reposition and left click to select it. Then drag with the mouse to move the label to its new position.
Right Click and Nudge
When you want to position the text very precisely, those types of adjustments are sometimes difficult to get just right, especially if you’re using the touch pad on a notebook. In these situations, right click the text you wish to select. Then, while you are hold the right mouse button down, use either the arrow keys or the W, A, S, and D keys on your keyboard to nudge the text into place.
