How can I add a Fit Curve to a particular class in a Class Scatter Plot?

Grapher allows users to define custom fits to graphs.  Grapher 15 Preview allows you to add a Fit Curve to one or more classes in a class plot. To do so:

  1. In the Object Manager, select the Class Scatter Plot you wish to add the fit curve to.
  2. Click Home | Add to Graph | Fit Curve
  3. In the Object Manager, select the fit curve object.
  4. In the Property Manager, click the Plot tab
  5. Expand the Fitted Plot section
  6. In the Class field, either choose a specific class to fit the curve to, or select (All).

To edit any aspect of the fit curve, you can select the fit curve in the Object Manager and then edit the various parameters (such as the Fit type and Plot Interval) In the Property Manager. More details on editing Fit Curves can be found here: Grapher Fit Curves Training Video
