Adding a title to an axis clarifies what is charted along that axis. Axis titles can be added to Area, XY-Plot, Bar, HiLo, HiLoOpenClose or Candle charts. The title or the annotation along the axis can also be rotated. To see how to rotate the axis annotation see, Axis Annotation Rotation.
Adding an Axis Title
Use the axis Text property to add a title to an axis. To remove the title, delete the default text for the AxisX or AxisY object.
Note: An axis title for the Y axis cannot be added to Polar, Radar or Filled Radar charts.
Rotating Axis Title
Use the Rotation property to rotate the axis title to 90, 180, or 270 degrees. The 90 and 270-degree rotations are most efficient for vertical axes.
