How can I edit the symbols and gradient fill in a Grapher class plot?

Grapher's class scatter plots allow the user to specify a number of properties associated with each class including the symbol, size, and color. To edit the symbols in a class plot:
  1. Create the class plot if it does not already exist.
    1. Click the Home | New Graph | Basic | Class Scatter Plot command (Class Scatter Plot icon).
    2. Select the worksheet and click Open.
  2. Click on the class scatter plot in the Object Manager.
  3. In the Property Manager, click on the Plot tab.
  4. Click the Edit button in the Classes field. The Edit Classes dialog appears.
  5. To change each class to a different symbol color, style, or size:
    1. Select the class and click the Properties button.
    2. In the Properties dialog, change the Symbol, Size, or any of the options in the Fill or Line sections.
    3. Click OK when the symbol has the correct shape, color, and size.
    4. Repeat these steps for each additional class.
  6. To change the size of all symbols in all of the classes:
    1. Click the Symbol sizes button.
    2. For incremental sizes, enter the desired Start at and Increment values and click OK.
    3. For fixed sizes, uncheck Use incremental size and enter the desired Default size and click OK.
  7. To change the symbol shape or color for all of the symbols in all of the classes:
    1. Click the Classes symbol button.
    2. Change the Symbol and any of the properties in the Fill or Line sections. Click OK and all of the symbols for all of the classes will update.
  8. To apply a color gradient to all of the class symbols:
    1. Click the Apply Gradient button.
    2. In the Gradient dialog, select your desired colormap and click OK.
    3. If desired, the gradient can be applied to just the line or just the fill but changing the apply gradient to field. This must be done prior to applying the gradient.
    4. After applying the gradient, changes to just one class can be made without re-entering the Gradient dialog. To change just one class color, double click on the symbol and edit the colors as desired.
  9. When all classes are showing the correct symbol, color, and size, click OK. Each class will show the proper symbol.
