Description
|
|
•
|
The pointplot3d function is used to create a three-dimensional plot of points. The points that are to be plotted come from the set or list L, the Matrix A, or the Vectors v1, v2, and v3.
|
•
|
The list may be either a list of points p, where p is a list or Vector containing three numbers, or a flat list whose length is a multiple of three.
|
•
|
The Matrix must be n by 3, where n is any positive integer. Each row of the Matrix contains the x-, y- and z-coordinates of a point. If a 3 by n Matrix is given, with n not equal to 3, then it will be automatically transposed. The Vectors, representing the x-coordinates, y-coordinates and z-coordinates respectively, can have any length, but all three must have the same length.
|
•
|
If you have a large number of points, it is recommended that the data be provided as a Matrix with datatype set to float.
|
•
|
A common error is to provide a sequence of points without putting them in a list. Note that pointplot3d([1,2,3], [4,5,6], [7,8,9]) is interpreted as the points (1,4,7), (2,5,8) and (3,6,9), and not as the points (1,2,3), (4,5,6) and (7,8,9).
|
•
|
The option connect=true specifies that the points are to be connected by line segments. In this case, L should be a list to ensure a consistent ordering of the points. This option is implied by the regular plot option style=LINE.
|
•
|
The option symbol=s specifies the symbol used in the display. See the symbol entry in the plot3d/option help page for a list of available symbols.
|
•
|
The option color=s specifies the color of the points. The allowable values for s are given in the plot/color help page. A list or Vector of n colors, where n is the number of points, may also be provided.
|
•
|
Remaining arguments are interpreted as options which are specified as equations of the form option = value. These options are the same as those available for the plot3d command, as described in plot3d/options.
