How to read the fish histogram

The bar graph shows size and proportion of fish in measuring area. The vertical axis shows
fish length (default setting) and the horizontal axis shows distribution. In the fish size
histogram display above, more than 50% of the fish in the measuring area are 10 cm in
length.
