A.4.5.13 Line3d Form

The Line3d form () draws a point-to-point line joining up the positions of the points in three dimensions. There are additional options to pre-sort the points by a given quantity before drawing the lines, and to colour the line along its length using an auxiliary coordinate.

Note that the line positioning in 3d and the line segment aux colouring is somewhat approximate. In most cases it is good enough for visual inspection, but pixel-level examination may reveal discrepancies.

Example Line3d plot

Line3d form configuration panel

The configuration options are:

Aux

If supplied, this controls the colour of the line along its length according to the value given here. As for the Aux shading mode, the details of the colour mapping are controlled using the Aux Axis control.

Sort

If supplied, this gives a value to define in what order points are joined together. If no value is given, the natural order is used, i.e. the sequence of rows in the table. Note that if the required order is in fact the natural order of the table, it's better to leave this value blank, since sorting is a potentially expensive step.

Thickness

Thickness of the line in pixels.
