How to make a residual plot

Briefly

With a scatter plot and a line or function, choose Make Residual Plot from the Graph menu.

A residual plot shows how far the points in a scatter plot are off of a line or function you have plotted.

1. First you need a scatter plot.

2. Then you need a line or a function plotted.

3. Then choose Make Residual Plot from the Graph menu.

4. The residual plot appears below the scatter plot. Its horizontal axis is "yoked" to the scatter plot's axis.

5. To get rid of a residual plot, select the graph and choose Remove Residual Plot from the Graph menu.

The Fine Print

The Graph menu doesn't exist unless the graph is selected.

If there's more than one line or function plotted in the scatter plot, you have to select the function (where it's written below the graph - not the line on the graph itself) to tell Fathom which function to make residuals from.

The Make Residual Plot and Remove Residual Plot commands also appear on a scatter plot's contextual menu. Just right-click (Windows) or -click (Mac) on a scatter plot and the menu pops up.
