Can I revert to a Simple plotting style from an Advanced plotting style?
A user can set a plotting style to Advanced mode, by which plotting styles can be more granular for Subtypes and different Pointages of rule.
So, in the above case, the line types of 0,105,125,170 etc will use the line type description for rule of Pointage3.
Note how the Advanced checkbox is disabled. This is intentional. If the user sets either Subtypes or Pointages for a series of line types, the selected plotting style will remain in Advanced mode the next time the user visits the plotting style.
To revert to Simple mode, i.e., be able to clear the Advanced button, clear any reference to Subtypes or Pointages in the line specification.
