     As far as marking on a chart, the symbols I use are triangles for electronic fixes, circles for visual or celestial fixes, circle with "r. fix" next to it for a running fix, rectangle for EP, and a half circle for DR.
    With the exception of an electronic fix, these are the standard symbols used by navigators (or at least those under the influence of Bowditch).   There seems to be no standard of notation for electronic fixes (none is given, for example, in Bowditch).   Some navigators use a triangle or other symbol that can't be confused with a DR, EP or Fix.   Other texts teach that one uses the standard symbol for a fix but then notes the source (GPS, Radar, Loran, etc)
