Alapeatükkides räägitakse antud teema ajaloost, Venni diagrammi olemusest ja kuidas seda luua. 2 1. VENNI DIAGRAMMI ÜLEVAADE 1.1. Ajalugu Nagu iga asi on saanud kusagilt alguse, nii on see ka Venni diagrammiga. Venni diagramm on saanud oma nime Briti loogiku ja filosoof John Venn´i käest, kes lõi selle 19. sajandi teisel poolel. Täpsemalt 1880. aastal John Venn populariseeris selle kasutamist oma raamatus pealkirjaga „On the Diagrammatic and Mechanical Representation of Propositions and Reasonings.” Kuid juba 13. sajandil kasutasid filosoofid ja matemaatikud sarnast diagrammi, nii võib oletada, et Venni diagramm on olemas olnud juba palju kauem. (A history…, 2013) Venni diagramm on sarnane Euler´i diagrammiga, mis loodi Leonhard Euleri poolt 18. sajandil. (The history…, 2013) Sellest võib järeldada, et paljud teadlased, filosoofid ja matemaatikud on sarnaseid diagramme kasutanud ka varemalt ning mida aeg edasi, seda
• Changing screen layout with windowed displays, text information in the margins, etc.; • Possibility of pull-down menus and other operator interaction devices being alongside the operational navigation display and so interacting with it; • Giving navigation and chart warnings such as "too close approach to safety contour"; "about to enter prohibited area"; "overscale display"; "more detailed (larger scale) data available" etc.; • Possibly, a diagrammatic representation of a computer evaluation of grounding danger; • Possibly, a diagrammatic representation of the immediate vicinity of the ship to aid in close quarters manoeuvring; and • Other future developments. (Further presentation requirements and techniques appropriate to ECDIS are likely to be developed in future). Probably no other display application is as demanding as that of ECDIS. Since colour is
