The density distribution of votes in 2,855 electoral divisions (Rallings C. & Thrasher M., 1985 — giving 1981 results) projected upon the electoral triangle and shown as surfaces from four different view points — by author, Ace Computing and !Works software.
The lower diagram shows how densely different parts of the triangle were covered by the results of county council elections in this year. Three peaks can be seen along the major two party axis — each of almost a quarter of a million votes, then a peak of 180,000 votes is next highest in Conservative territory by the Labour margin. The side views show what the surface would look like viewed from their respective angles. The top diagram shows the view, looking down slightly on the surface, from above the Liberal apex.
