How to Add an Average Line in Excel
Adding an average line to your Excel chart helps to easily visualize the overall trend of your data. This task can be completed quickly by inserting a new series to your chart that represents the average value. You’ll go through steps like calculating the average, adding it to your data range, and then customizing your chart to display the average line clearly.
Step by Step Tutorial on How to Add an Average Line in Excel
We’re going to walk you through the process of adding an average line to your Excel chart. This will involve calculating your average, incorporating it into your data set, and then displaying it on your chart.
Step 1: Calculate the Average
First, calculate the average of your data set.
To do this, select an empty cell and use the AVERAGE function. For example, if your data is in cells A1 to A10, you would type =AVERAGE(A1:A10) and press Enter. This will give you the average of your data range.
Step 2: Insert a New Series
Next, insert this average value into your data range.
Copy the average value you just calculated. Now, paste this value next to the original data points. Your new data range should have a column for the original data and a column for the average values.
Step 3: Select Data for the Chart
Select the data you want to include in your chart.
Highlight your original data and the new column containing the average values. This step ensures that both the data points and the average values will be included in the chart.
Step 4: Create the Chart
Now, create the chart.
Go to the Insert tab, select your preferred chart type (e.g., Line Chart), and insert it. Your chart should now display both the original data and the average values.
Step 5: Customize the Average Line
Finally, customize the appearance of the average line.
Click on the average line in your chart. Right-click and select Format Data Series. Change the line color and style to distinguish it from the original data points, making it easily visible.
After completing these steps, your chart will display an average line that helps you quickly understand the overall trend of your data.
