How do I move the x axis down?

How do I move the x axis down? I have a bar graph made, and the words; Bright,Dim,Dark are in the middle of it. How do I move it down?

Double click on your chart to go into edit mode. Right-click on X-axis and select “Format Axis”. Under the tab “Positioning” you find a field “Place labels”. Select “Near Axis” that brings them under the x-axis.

If you have negative numbers on the y-axis, select the first field “Cross Other Axis at”.
