Finding a Line of Best Fit in Excel

To determine the line of best fit in Excel, select your data and choose an appropriate chart type, such as an XY scatter or line graph, which supports trendlines.

Adding a Trendline to Your Chart

After creating your chart, right-click on the data series and select 'Add Trendline' from the context menu. Excel offers various trendline types, including linear, polynomial, and exponential, which can be selected based on your data pattern.

Customizing Your Trendline

You can customize the trendline's appearance by adjusting its color, width, and style. To extend the trendline for forecasting, select 'Format Trendline' and choose the 'Forecast' option, specifying the number of periods to project.

Displaying Trendline Equations

For analytical purposes, displaying the trendline equation on the chart can be beneficial. Check the 'Display Equation on chart' option in the 'Format Trendline' menu to show the equation, useful for calculations and predictions.

Trendline Limitations

Note that trendlines cannot be added to 3-D, pie, radar, and other specific types of charts. For charts with multiple data series, add and format trendlines individually for each series.
