As Excel is one of the most widely used spreadsheet programs in the world, it’s important to master its features, including adding a secondary axis. One of the key challenges of data visualization is displaying two or more sets of data with vastly different ranges on the same chart, making secondary axis crucial. In this guide, we’ll take you through a step-by-step tutorial of how to add a secondary axis in Excel, with plenty of real-life examples, and best practices to help you take your charts to the next level.
II. Step-by-Step Tutorial
Before we get started, it’s important to understand what the secondary axis is and when it’s appropriate to use it. The secondary axis is a second vertical or horizontal axis that represents a second set of data on the same chart.
In this step-by-step tutorial, we’ll look at how to add a secondary axis in Excel in a few easy steps:
A. Overview of the Process
1. Select the data you want to chart, including your secondary data series.
2. Click on the Insert tab and select the type of chart you want to use.
3. Change the chart type of the secondary data to a line or column chart type.
4. Select the secondary data series and move it to the secondary axis.
5. Format the chart to make sure it’s easy to read and understand.
B. Detailed Explanation of Each Step
1. Select the data you want to chart, including your secondary data series. Make sure your data is organized with your primary data series in a column or row, followed by your secondary data series in the next column or row.
2. Click on the Insert tab and select the type of chart you want to use. Excel offers a wide range of chart types, including bar charts, column charts, line charts, and more. Select the chart type that best suits your data and your visualization goals.
3. Change the chart type of the secondary data to a line or column chart type. Right-click on the secondary data series and select “Change Series Chart Type.” Choose a line or column chart type for the secondary data series.
4. Select the secondary data series and move it to the secondary axis. Right-click on the secondary data series and select “Format Data Series.” In the “Series Options” menu, click on “Secondary Axis.”
5. Format the chart to make sure it’s easy to read and understand. There are many ways to format a chart, including adjusting the colors, fonts, and layout. Make sure to label both axes clearly, and consider adding a descriptive title to the chart.
C. Use of Screenshots and Diagrams
Adding screenshots and diagrams can be very helpful when visualizing the process. Here are a few examples:
D. Emphasis on Important Points and Potential Pitfalls
It’s important to be aware of a few potential pitfalls when adding a secondary axis:
- Be cautious of overcrowding your chart with too much data.
- Make sure both axes are labeled and easy to read.
- Consider removing gridlines or formatting them to improve clarity.
- Test your chart with different viewing options to ensure that it’s easy to interpret.
III. Quick Tips
Here are some quick tips for adding a secondary axis in Excel:
- Make sure your data is organized correctly before starting.
- Select the appropriate chart type based on your data and visualization goals.
- Don’t be afraid to experiment with different formatting options.
IV. Examples and Use Cases
Knowing when and why to use a secondary axis is crucial to effective data visualization. Here are a few use cases:
A. Explanation of When and Why a Secondary Axis is Useful in Data Visualization
The secondary axis is useful when comparing two data series that have vastly different ranges. For example, if you are comparing the number of website visitors per month with the number of sales per month, your website traffic may be in the tens of thousands, while your sales may only be in the hundreds. Comparing these two data points on the same chart can be difficult without a secondary axis.
B. Real-life Examples of How to Implement it
Here are a few examples of when it may be appropriate to use a secondary axis on a chart:
- Comparing website traffic and sales data in a single chart.
- Displaying two different types of data, such as temperature and humidity, in a single chart.
- Charting multiple time series data points – such as sales and expenses – on a single chart.
C. Scenarios Where a Secondary Axis Would Be Useful
A secondary axis can be useful in many scenarios, including:
- Comparing two different types of data.
- Displaying multiple time series data points on a single chart.
- Charting data sets with vastly different ranges.
V. Best Practices
Here are some best practices to follow when designing charts with secondary axes:
A. Tips for Designing Effective Charts with Secondary Axes
- Make sure that both axes are labeled clearly and easy to read.
- Consider using different colors or symbols for each data series to improve readability.
- Avoid cluttering the chart with too much data. Only include data that is relevant and necessary to the viewer.
- Test the chart with different viewing options to ensure that it’s easy to interpret.
B. Explanation of Common Design Mistakes to Avoid
- Don’t overcrowd your chart with too much data.
- Don’t forget to label your axes clearly.
- Avoid using too many colors or symbols that may confuse the viewer.
- Avoid using a secondary axis for data series that are relatively close in range.
C. Emphasis on Important Design Considerations
When thinking about how to design a chart with a secondary axis, it’s important to consider the following:
- What is the primary purpose of the chart?
- Who is the intended audience?
- What relevant data should be included or excluded?
