Just a note

Notice that, because this distribution is very skewed, we have plotted the number of individuals per species using a logarithmic scale. The height of each bar in the first graph shows the number of species represented by the same number of individuals. Green points show a log series distribution fitted to these data.
  • The second graph shows the same data as a cumulative distribution.
  • The third graph shows the same data with the axes rearranged - and is sometimes described as a Whittaker plot. Be aware that, depending upon which model an author prefers, either scale may be presented logarithmically or linearly. These plots are sometimes used to select the parametric model.
