How to add, remove or reposition text used to label each axis? | Excel 2007

Click on the chart and go under Chart Tools and Layout tab. In Labels section click on “Axis Titles” and from the appearing menu choose which axis you wish to edit. From the next selection determine whether you wish for the title to show up or not. Also choose the placement for the title if you decide to show it on the chart. Unfortunately no live preview is shown however you get a pretty good image of the display from the little picture before every selection.
