Method: PLplot.plot3d

Defined in:
ext/rbplplot.c

.plot3d(x, y, z, opt = nil, clevel = nil) ⇒ nil .plot3dc(x, y, z, opt = nil, clevel = nil) ⇒ nil

If clevel is true (or non-zero Fixnum), draw sides (same as including PL::DRAW_SIDES in opt), but not contours. If clevel is false (or zero Fixnum), do not draw sides (even if opt includes PL::DRAW_SIDES) and do not draw contours. Otherwise, sides are drawn if PL::DRAW_SIDES is in opt and contours are drawn at the levels specified in clevel if it is non-nil.

Overloads:

  • .plot3d(x, y, z, opt = nil, clevel = nil) ⇒ nil

    Returns:

    • (nil)
  • .plot3dc(x, y, z, opt = nil, clevel = nil) ⇒ nil

    Returns:

    • (nil)
