With the data available (and because the question is interesting), two
additional comments:

+ you may ease managing user-defined tics with exponential notation
  like e.g., in Fortran:

  ```
set format y "%.0f"
set ytics font "verdana,10" add \
              (  0         0, \
               "1M"  1e06, \
               "2M"  2e06, \
               "4M"  4e06, \
               "6M"  6e06, \
               "8M"  8e06, \
              "10M"  1e07, \
              "12M" 1.2e7, \
              "14M" 1.4e7)
   ```

+ gnuplot actually may add SI prefixes (k, M, etc.) on the scales for
  you and show user-defined tics.  For this to happen, drop "set
  format y "%.0f" to try instead

  ```
set format y '%.0s %c'

set ytics font "verdana,10" add \
("25 M"   2.5e7)  # only shown for the ordinate scaling by lg

set logscale y  # i.e., the implicit form of "set logscale y 10"
  ```

  The plot then retains an obvious hint something happened to
  "katzeilla" and "rjc" during the first interval of recording while
  the relative variation of the other traces was smaller.  Credit to
  stackoverflow user Christoph for the showcase[1] about the
  alternative format.

  Perhaps altogether with an instruction like "set yrange[1000:1e9]"
  this may justify to move/reorganize the keys a little bit.
