Whether a method is used in a profile is determined by its mode: ON or OFF. Double-click a method to toggle its mode.
The Size column specifies the size of the method. The size is the method's graph size in relation to the other method graphs. If all methods have a size of 1, then they will all be the same height. If one method has a size of 2, it will be double the height of the methods with a size of 1.
The value in the Line column specifies which function line color (see Color Schemes) to use to draw the method's function. You can change the line value by right-clicking on the method and selecting the context menu item line.
The Segs column indicates if segments will be displayed in the graphs or not. You can turn segments on and off via the context menu item Segments -> On / Off. You can modify how and where segments are drawn by opening the Segment Markers dialog (press the Segs button.).
