Manhattan plot

A Manhattan plot is a type of scatter plot, usually used to display data with a large number of data-points - many of non-zero amplitude, and with a distribution of higher-magnitude values, for instance in genome-wide association studies.

It gains its name from the similarity of such a plot to the Manhattan skyline: A profile of skyscrapers towering above the lower level "buildings" which vary around a lower height.
