Authors: Maurice d' Ocagne (1862-1938)
The first alignment diagrams, using sets of parallel axes, rather than axes at right angles; development of the essential ideas used in parallel coordinates plots. [Using the principle of duality from projective geometry, d'Ocagne (1885) showed that a point on a graph with Cartesian coordinates transformed into a line on an alignment chart, that a line transformed into a point, and, finally, that a family of lines or a surface transformed into a single line cite(Hankins:1999)]

Author: Edward Walter Maunder (1851-1928)
Use of the "butterfly diagram'' to study the variation of sunspots over time, leading to the discovery that they were markedly reduced in frequency from 1645--1715 (the "Maunder minimum''). [Earlier work, started in 1843 by H. Schwabe, showed that sunspots exhibit an approximately twenty-two year cycle, with each eleven-year cycle of sunspots followed by a reversal of the direction of the sun's magnetic field]
