   • 2006, M. Ghoreychi, “Coupled processes involved in post-mining”, in Alain van Cotthem, Robert Charlier, Jean-Francois Thimus, editor, Eurock 2006: Multiphysics Coupling and Long Term Behaviour in Rock Mechanics, page 50:

     Evolution of P waves velocity induced by flooding-drying monitored by seismic diagraphy within the intercalary marl (Balland & Mazière in GISOS, 2005).

   • 2012, M. J. Walker, Hot Deserts: Engineering, Geology and Geomorphology, page 209:

     Diagraphy probing is particularly suited to locating rockhead and the identification of cavities in the karstic environment.

   • 2012, Etienne du Trémolet de Lacheisserie, Damien Gignoux, Michel Schlenker, Magnetism: II-Materials and Applications, page 391:

     The measurement apparatus (impedance bridge type) have a sensitivity of 10^-15 to 10^-16 in the field or in diagraphy (borehole logging), and 5×10^-8 in the laboratory, the values encountered range from -10^-5 to 1.

   • 2013, André Revil, Abderrahim Jardani, The Self-Potential Method, page 15:

     It was first commercially used in geophysics by Conrad Schlumberger (1920), especially as a downhole measurement tool for diagraphy;

2. (obsolete) The use of X-ray imagery; radiography.
   • 1910, Frederick Dessauer, “A New Method of Instantatneous Radiography”, in Archives of the Roentgen Ray, volume 14, page 258:

     In addition, a number of new possibilities would be opened up to diagraphy – e.g., radiography of movements, kinematographic radiography, and radiography of those in a state of convulsion.

   • 1939, American Review of Tuberculosis and Pulmonary Diseases, page 138:

     Furthermore, kymographic pictures are hazy and sometimes distorted, while the pictures obtained by diagraphy are sharp and unobstructed.

   • 1939, American Quarterly of Roentgenology - Volume 42, page 139:

     To judge by the illustrations and text, diagraphy has so far found its greatest application in the study of the chest .

3. The process of changing the way something is expressed or transcribed from one medium to another.
   • 2006, David Nadelberg, Mortified:

     And hence, to ward off such criticism, the concept of the "diagraphy" was born —Mortified's odd editorial process by which we assemble actual childhood words into unique autobiographical tales.

   • 2017, Costica Bradatan, Camil Ungureanu, Cinema and Sacrifice, page 149:

     Lyotard thus characterises mise-en-scène as a somatography: a transcribing of linguistic signifiers on and for bodies, and as a diagraphy: a change in the space of transcription, from linguistic signifiers (primary space) to sensations affecting the bodies of the audience (the other space).

   • 2019, Abdelkebir Khatibi, Plural Maghreb: Writings on Postcolonialism:

     This is a question of the madness of writing through several languages, in a genealogical diagraphy.

4. The teaching of drawing in Ancient Greece using a stylus on a wax-covered wooden tablet, or this technique of drawing on wax.
   • 1794, Cornelius Pauw, Philosophical Dissertations on the Greeks - Volume 1, page 151:

     Diagraphy, or the study of drawing, was then introduced as an essential part; and as such it has been considered both by Aristotle and Pliny.

   • 1880, Joseph Maberly, Theodore Henry Fielding, Robert Hoe, The Print Collector, page 318:

     It includes stereotypeing and automatic or chemical engraving in relief, as well as machines for the purpose of making engravings, pantography, diagraphy, glyphography, electrotypography, and a variety of other curious processes.

   • 2009, Ernst van de Wetering, Rembrandt: The Painter at Work, page 59:

     One might deduct from this passage that the portrayal of young apprentices with a drawing board may have been a reference to antigue 'diagraphy' (see also fig. 68) and, besides referring to Usus, played a role in elevating the status of the art of drawing and painting.
