This work by Cheysson and Fontaine, reported by Bertillon, was the first proposal of standards for graphical presentation. The paper "Proposals to bring uniformity in the preparation of charts" discusses some key recommendations, including cautious use of symbols and hieroglyphs, and sparing use of comparison by areas.
It is proposed that x and y scales be constructed so that the average behaviour corresponds to a curve of 45 degrees. Other attempts to formulate standards for graphical procedures at the International Statistical Congress are discussed in detail.
