Understanding the Basics of Chart Axis Labels

Before we jump into the step-by-step process of adding labels to your chart axes, it’s important to understand the basics.

Axis labels are essential for clearly conveying the information in your chart, they provide context and guide the reader in interpreting the data.

Horizontal Axis Label

The horizontal axis, also known as the x-axis, typically represents categories or time periods in a chart. Horizontal axis labels are placed along the x-axis to indicate the specific points or intervals being represented.

For example, in a chart displaying monthly sales data, the horizontal axis labels would be the names of the months.

The vertical axis, also known as the y-axis, represents the numerical values or measurements in a chart. Vertical axis labels are placed along the y-axis to provide the scale and units of measurement for the data points.

For instance, in a chart showing revenue growth, the vertical axis labels might display percentages.
