How do you read a graph with two y axis?

A second Y axis is a Y axis drawn on the right-hand side of a chart. It can show the same axis scale as the primary Y axis or a different scale. You can use a second Y axis with the same scale as the primary Y axis on a wide chart to help viewers interpret the data more easily.

When should you use a secondary axis?

It should only be used when you are trying to show that one data series moves in or out of sync with another data series. The reason that a second axis is required is that the measurement units for the two data series are different. If the measurement unit was the same, a simple line graph would be used.

Here’s the problem in a nutshell: The scales of dual axis charts are arbitrary and can therefore (deliberately) mislead readers about the relationship between the two data series.
