To specify the font for textplot and textplot3d, use the fontoption. In the following plot, the origin, a saddle point, is labelled P .> d := plot3d( x^2-y^2, x=-1..1, y=-1..1 ):> e := textplot3d( [0, 0, 0, "P"],> font=[HELVETICA, OBLIQUE, 22], color=white ):> display( [d,e], orientation=[68,45] );P5.6 Special Types of PlotsThe plots package contains many routines for producing special typesof graphics. This section provides example commands for plotting thefollowing.
