In Excel, the secondary axis is used when you have two sets of data with different scales or units of measurement. By adding secondary axis excel, you can visually compare and analyze two data series with different ranges or magnitudes.

For instance, you have a sales chart with revenue and units sold. Revenue may be measured in dollars, while units sold may be measured in thousands. In this case, plotting both series on the same primary axis may make it difficult to interpret the chart accurately. Adding a secondary axis would help you to scale and display the two data series appropriately, making it easier to understand their relationship.

Using a secondary axis allows you to easily display multiple data series in a single chart, enhancing your data’s visual representation.
