5 3D Renderers
5.1 3D Renderer Function Arguments
Required (and possibly optional) arguments representing the graph to plot.
Optional keyword arguments for overriding calculated bounds, with the default value #f.
Optional keyword arguments that determine the appearance of the plot.
The optional keyword argument #:label, which specifies the name of the renderer in the legend.
See 2D Renderer Function Arguments for a detailed example.
