|
21 ## Plot a three-dimensional stem graph and return the handles of the line |
|
22 ## and marker objects used to draw the stems. The default color is @code{"r"} |
|
23 ## (red). The default line style is @code{"-"} and the default marker is |
|
24 ## @code{"o"}. |
|
25 ## |
|
26 ## For example, |
|
27 ## @example |
|
28 ## theta = 0:0.2:6; |
|
29 ## stem3 (cos (theta), sin (theta), theta) |
|
30 ## @end example |
|
31 ## |
|
32 ## @noindent |
|
33 ## plots 31 stems with heights from 0 to 6 lying on a circle. Color |
|
34 ## definitions with rgb-triples are not valid! |
