A combined axis chart merges two or more measures into a single axis, allowing for a direct comparison between those measures within the same visual context. This approach makes it easier to analyze the relationship between the measures, as they are displayed on the same scale and can be compared more readily. This type of visualization is particularly useful when the measures share a common unit of measurement or are closely related in terms of the data being analyzed.

For example, if you're analyzing sales revenue and profit over time, combining these two measures into one axis allows you to see how profit margins have changed in relation to overall sales. This type of chart optimizes the use of space in a visualization and enhances the viewer's understanding of the data by providing a clearer picture of trends and correlations between the measures.
