This frequency histogram sample shows the relative species abundance of beetles sampled from the river Thames. It was designed on the base of the Wikimedia Commons file: PrestonPlot beetles.png.

"Relative species abundance is a component of biodiversity and refers to how common or rare a species is relative to other species in a defined location or community. Relative species abundances tend to conform to specific patterns that are among the best-known and most-studied patterns in macroecology. ...
Relative species abundance distributions are usually graphed as frequency histograms (“Preston Plots”) or rank-abundance diagrams ("Whittaker Plots”)." [Relative species abundance. Wikipedia]
The frequency histogram example "Beetles in the river Thames" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Histograms solution from the Graphs and Charts area of ConceptDraw Solution Park.

How Do You Make a Histogram?

How do you make a histogram usually? Drawing of histogram is quite complex and lengthy process. Usually you have a set of data and you draw free-hand your diagram according to these data. But now thanks to the ConceptDraw PRO diagramming and vector drawing software extended with Histograms solution from the Graphs and Charts Area of ConceptDraw Solution Park this process became simple and fast.
