An Axis provides end-users with a visual means for reading and analyzing the data displayed within the diagram. Most charts contain two axes: a numerical axis of values (Y-axis) and an axis of arguments (X-axis). To review the concepts of a series point’s value and arguments, and the way in which axes are associated with series, refer to Charting Basics.


In addition to primary axes, you can also associate a chart’s series with secondary axes, which are almost identical to primary axes. Both primary and secondary axes can be distributed among multiple panes, if required.

Refer to the following help topic for more details: Axes.

An axis (primary or secondary) allows you to access and customize the following chart elements:

The table below lists the main properties that affect the element’s appearance and functionality:
