The horizontal X axis of a chart is also known as the category axis.
The vertical Y axis of a chart is also known as the value axis.
The Z axis of a chart is also known as the series axis. It is only available for certain three-dimensional chart types.
Note: The X axis and Y axis are shown automatically when the chart is created.
To show or hide an axis, proceed as follows:
Via the "Add chart element" icon
You can use the Add chart element icon 
on the contextual ribbon tab Chart to show or hide the X axis and/or Y axis (the Z axis only in the dialog box, see below).
To do so, select the chart and use the ribbon command Add chart element to select the entry Axis. In the following submenu, you can use the entry Primary horizontal to show or hide the X axis and Primary vertical to show or hide the Y axis.
The entry More takes you to a dialog box with additional options (see below).
Axis title: To add, change or remove axis titles, proceed as follows:
▪Adding axis title
| If you want to add an axis title to the axis, choose the ribbon command Add chart element and then select the entry Axis title. Primary horizontal shows an axis title for the X axis, while Primary vertical shows it for the Y axis. |
| The entry More also takes you to the dialog box here (see below). |
▪Changing an axis title
| To rename an axis, double-click on the axis title and switch to the Text tab in the following dialog box. Enter the desired text here. |
▪Removing an axis title
| To remove an axis title, hide it again via the command Add chart element or select it directly in the chart and press the Del key. |

| 1. | Select the chart by clicking on it. |
