How to Add Average Line to Chart in Google Sheets
An average is a single number that represents a group of numbers, typically the sum of the numbers divided by the number of numbers in the group. Adding an average line into a chart will help readers or viewers visualize the average of a set of data. A center horizontal line would be added to charts if an average line was added.
Once you are ready, we can get started by using real-life scenarios to help you understand how to add an average line to a chart in Google Sheets.
Adding Average Line to Chart
Before we begin we will need a group of data to be used to create a chart and calculate an average.
Make sure your group of data is displayed in a clean and tidy manner. This will help us to create the chart easily.
Next, you need to calculate the average of the data group by using the AVERAGE function.
Select the entire data cell, choose Insert, and select Chart.
By default, Google Sheet will use the selected group of data to generate a combo chart.
Now, you can customize the chart to your preference. We will change the chart title to ‘Sales’ for a better representation of the chart. Also, to emphasize the chart title, we will change the text color to black, bold it, and also align it to the center.
Once you are done editing and customizing the chart, it will look something like this. You can see the average of the entire dataset is shown using a red line.
You can pretty much have an average line on any type of chart in Google Sheets. Here is another example of adding the average line on a line chart
