How to Make a Google Sheet Trendline: A Step-by-Step Guide

Creating a trendline in Google Sheets is a handy way to visually display trends in your data. It’s a straight line that best fits the data points on a chart, making it easier to understand the overall direction of the data. Whether you’re presenting to a class or analyzing business metrics, a trendline can be a valuable tool. Let’s dive into how you can add one to your chart in Google Sheets.

Step by Step Tutorial: How to Make a Google Sheet Trendline

Before we get into the steps, it’s important to understand what we’re aiming for. Adding a trendline to your chart will help you identify patterns and make predictions based on your data. It’s a simple process that Google Sheets can do for you with just a few clicks.

Step 1: Select your chart

Click on the chart to which you want to add a trendline.

When you create a chart in Google Sheets, it becomes an object on your spreadsheet. To add a trendline, you first need to select the chart by clicking on it.

Step 2: Open the Chart Editor

Click on the three vertical dots in the upper right corner of the chart and select ‘Edit chart’.

Once you select your chart, you’ll see a toolbar around it. The three vertical dots open a dropdown menu where you can find various options to modify your chart, including the ‘Edit chart’ option to access the Chart Editor.

Step 3: Navigate to the Customize tab

In the Chart Editor, click on the ‘Customize’ tab.

The Chart Editor has two main tabs: ‘Setup’ and ‘Customize’. The ‘Customize’ tab has various options to tweak the appearance of your chart, including the addition of a trendline.

Step 4: Add a trendline

Scroll down and find the ‘Series’ section, then click on it to expand it. Select the data series you want to analyze and check the ‘Trendline’ box.

In the ‘Series’ section, you can select which data series you want to add a trendline to. Once you find the correct series, simply check the ‘Trendline’ box to add it to your chart.

Step 5: Customize your trendline

Customize the trendline’s color, line style, and label as needed.

Google Sheets allows you to make your trendline stand out by changing its color and line style. You can also label your trendline for clarity, especially if you have multiple trendlines on the same chart.

After completing these steps, your chart will now display a trendline that represents the general direction of your data series. This can help you easily see the trend and make more informed decisions or predictions based on your data.

Tips: Making the Most of Your Google Sheet Trendline

  • Experiment with different types of trendlines, such as linear, exponential, or polynomial, to see which best represents your data.
  • Use the ‘Label’ option to clearly identify what each trendline represents, especially if your chart contains multiple data series.
  • Adjust the ‘Opacity’ of your trendline to make it stand out or blend in with your chart.
  • Consider removing outliers from your data series before adding a trendline for a more accurate representation.
  • Use the ‘Forecast’ option to extend your trendline beyond your data range to predict future values.
