Vector fields and 3D scatter graphs.

New graph styles for tables of many variables (Graph › Graph Style, or Format Graph › Graph)

• 3D scatter: the first three variables as X, Y and Z, coloured by a fourth when there is one. Tilt and turn the view in Format Graph.
• Vector field: an arrow at each X, Y with its two components from the next two variables, coloured by its length. Arrows are scaled so the longest is about the distance between neighbouring arrows.
