Problems with Residual Plots

Troubleshooting > Problems with Graphs > Problems with Residual Plots

When there is more than one thing plotted on the graph, the residual plot is based on the function selected when the residual plot is made.

If you have selected a graph that has functions or computed lines on it and Make Residual Plot is disabled, you need to select the line or function on which you want the residual plot to be based. (Click the line itself or its equation.)

If a residual plot is based on the wrong function, click the function on which you want it based, and the residual plot will change.

See Make a Residual Plot.
