Why were dual axes used in the line chart?
As you can see, dual axis charts are often used to show two different data series with a different magnitude (=number range) and/or measure (GDP, life expectancy, etc). Often, their goal is to compare two trends with each other.
Can you have 2 y-axis on a graph?
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.
What is a dual axis line chart?
A dual axis chart (also called a multiple axes chart) uses two axes to easily illustrate the relationships between two variables with different magnitudes and scales of measurement. The relationship between two variables is referred to as correlation.
