How to Make a Scatter Plot in Google Sheets

In Google Sheets, enter your X values in column A and Y values in column B with headers. Select both columns, then click Insert → Chart. In the Chart Editor, set the chart type to “Scatter chart.” To add a trendline, click Customize → Series → check “Trendline.” You can also display the R² value to show how well the line fits. For faster results with no spreadsheet setup, paste your X,Y pairs directly into this tool.

What Does a Scatter Plot Show?

Scatter plots reveal the relationship (correlation) between two continuous variables. Points clustered along a diagonal indicate positive correlation; a downward slope indicates negative correlation. Random scatter indicates no linear relationship. The trendline shows the best-fit linear model.

FAQ

What format does the data need to be in?

Each row is one point. Use comma or tab to separate X and Y values. Example: 1.5,3.2

What is the trendline?

An ordinary least squares (OLS) linear regression line. It minimizes the sum of squared vertical distances from each point to the line.
