Intro
Master data visualization with 5 ways to create a dual Y axis chart, enhancing comparison and analysis of multiple datasets, trends, and metrics in a single graph.
When it comes to data visualization, one of the most effective ways to compare two different datasets is by using a dual Y-axis chart. This type of chart allows you to plot two sets of data with different units or scales on the same graph, making it easier to analyze and understand the relationships between them. In this article, we will explore five ways to create a dual Y-axis chart, along with their benefits and limitations.
A dual Y-axis chart is particularly useful when you want to compare two datasets that have different units or scales. For example, you might want to compare the sales revenue of a company with the number of customers it has. In this case, a dual Y-axis chart would allow you to plot the sales revenue on one axis and the number of customers on the other, making it easier to see the relationship between the two datasets.
Another benefit of dual Y-axis charts is that they can help to identify trends and patterns in the data that might not be immediately apparent when looking at the datasets separately. By plotting the two datasets on the same graph, you can see how they relate to each other and identify any correlations or anomalies.
What is a Dual Y Axis Chart

A dual Y-axis chart is a type of graph that uses two separate Y-axes to plot two different datasets. The two axes are usually positioned on either side of the chart, with one axis on the left and the other on the right. This allows you to plot two datasets with different units or scales on the same graph, making it easier to compare and analyze them.
Benefits of Dual Y Axis Charts
The benefits of dual Y-axis charts include: * Allowing you to compare two datasets with different units or scales on the same graph * Helping to identify trends and patterns in the data that might not be immediately apparent when looking at the datasets separately * Enabling you to see the relationship between two datasets and identify any correlations or anomalies * Providing a clear and concise way to present complex dataHow to Create a Dual Y Axis Chart in Excel

Creating a dual Y-axis chart in Excel is relatively straightforward. To do this, follow these steps:
- Select the data you want to plot on the chart
- Go to the "Insert" tab and click on the "Chart" button
- Select the type of chart you want to create (e.g. line chart, bar chart, etc.)
- Click on the "OK" button to create the chart
- Right-click on the chart and select "Select Data"
- In the "Select Data Source" dialog box, click on the "Add" button
- Select the second dataset you want to plot on the chart
- Click on the "OK" button to add the second dataset to the chart
- Right-click on the chart and select "Chart Options"
- In the "Chart Options" dialog box, click on the "Axes" tab
- Select the "Secondary Axis" option
- Click on the "OK" button to apply the changes

Creating a dual Y-axis chart in Google Sheets is similar to creating one in Excel. To do this, follow these steps:
- Select the data you want to plot on the chart
- Go to the "Insert" menu and select "Chart"
- Select the type of chart you want to create (e.g. line chart, bar chart, etc.)
- Click on the "Insert" button to create the chart
- Click on the "Three vertical dots" icon in the top right corner of the chart
- Select "Advanced edit"
- In the "Chart editor" dialog box, click on the "Customize" tab
- Select the "Series" option
- Click on the "Add series" button
- Select the second dataset you want to plot on the chart
- Click on the "OK" button to add the second dataset to the chart
- In the "Chart editor" dialog box, click on the "Axes" tab
- Select the "Secondary axis" option
- Click on the "OK" button to apply the changes

Creating a dual Y-axis chart in Python can be done using the matplotlib library. To do this, follow these steps:
- Import the matplotlib library
- Create a figure and axis object
- Plot the first dataset on the axis
- Create a secondary axis on the right side of the chart
- Plot the second dataset on the secondary axis
- Set the title and labels for the chart
- Display the chart
