2-10-2-1 Changing the vertical axis
The vertical axis can be changed with both the frequency and graph vertical
axis intervals.
For the FREQUENCY, the maximum value of the vertical axis can be
changed. When the fish length distribution frequency is uniformly wide, it is
recommended to increase the frequency value, and when the distribution is
narrow, it is recommended to decrease the value.
Fig. 2-36 FISH LENGTH GRAPH: Frequency percentage change (20 - 100/in steps of 10)
By changing the intervals of the graph vertical axis, you can change the
intervals of the frequency. To know the frequency value in detail, it is
recommended to decrease the frequency value. To know the approximate
frequency value, it is recommended to increase the frequency value.
