Set Root Property Values

Set graphics root property values by storing the object handle and using dot notation.

r = groot;
r.ShowHiddenHandles = 'on';

Tips

• Use the graphics root object to set default values on the root level for other types of objects. For example, set the default colormap for all future figures to the summer colormap.

  set(groot,'DefaultFigureColormap',summer)

  To restore a property to its original MATLAB^® default, use the 'remove' keyword.

  set(groot,'DefaultFigureColormap','remove')

  For more information on setting default values, see Default Property Values.
