This time referring correctly to the "Buhlmann M-value gradient". I've also added percentage characters to the values, and used horizontal blue lines (like Willem) to show the link between the equal values on the two graphs. By default, the manual opens in a non-maximized window and the menu frame takes up nearly a quarter of the width (on my laptop at least). I've narrowed the overall graphic width so that the entire image can be displayed without needing to scroll across or enlarge the window. Cheers, Rick
