When the increase in magnitude of the breakpoints on the A-axis is not in numerical order
Linearization is done by excluding the deviating points.
This can be done so that breakpoints in the middle are not used. (Breakpoint 3 in
the graph below)
This can be done so that excess breakpoints are not used. (Breakpoints 7 to 10 in
the graph below)
A-axis
(input)
Breakpoint 3 (A3, B3)
Breakpoint 5 (A5, B5)
Breakpoint 4 (A4, B4)
Breakpoint 2 (A2, B2)
Breakpoint 1 (A1, B1)
A3 is less than
A2 so is excluded
A7 to A10 are less than
A6 so are excluded
Breakpoint 7 (A7, B7) to
breakpoint 10 (A10, B10)

When two adjacent breakpoints have the same value on the A-axis
The breakpoint with the smaller number is valid. Also, the two points cannot be
connected by a straight line.
A-axis
(input)
Breakpoint 4 (A4, B4)
Breakpoint 3
(A3, B3)
Breakpoint 2 (A2, B2)
Breakpoint 1 (A1, B1)
If A2 = A3, breakpoint 2 is valid.
