I based the design off a graph from Kodak's R&D department or at least from the couple of sheets Dick Dickerson gave me. Each dot is Δ0.02 logs apart. Each square is Δ0.1 log. The solid lines represent Δ1.0 logs. The coordinates are labeled every 0.2 logs. This design is very good for easy to read precision plotting, especially by hand. For my four quadrant curves which are meant to incorporate a larger view of the process has the coordinates labeled in Δ0.30 log intervals.
