p = plot(sin(x))
If the line_color
aesthetic is a function of arity 1 then the coloring is a function of the x value of a point.
p[0].line_color = lambda a : a
p.show()
If the arity is 2 then the coloring is a function of both coordinates.
p[0].line_color = lambda a, b : b
p.show()
p = plot(x*sin(x), x*cos(x), (0,10))
If the arity is 1 the coloring depends on the parameter.
p[0].line_color = lambda a : a
p.show()
For arity 2 the coloring depends on coordinates.
p[0].line_color = lambda a, b : a
p.show()
p[0].line_color = lambda a, b : b
p.show()
Arity 1 - the first parameter. Arity 2 or 3 - the first two coordinates or all coordinates.
p = plot(sin(x)+0.1*sin(x)*cos(7*x),
cos(x)+0.1*cos(x)*cos(7*x),
0.1*sin(7*x),
(0, 2*pi))
p[0].line_color = lambda a : sin(4*a)
p.show()
p[0].line_color = lambda a, b : b
p.show()
p[0].line_color = lambda a, b, c : c
p.show()
p = plot(sin(x)*y, (0,6*pi))
Arity 1, 2 or 3 for first, the two first or all coordinates.
p[0].surface_color = lambda a : a
p.show()
p[0].surface_color = lambda a, b : b
p.show()
p[0].surface_color = lambda a, b, c : c
p.show()
p[0].surface_color = lambda a, b, c : sqrt((a-3*pi)**2+b**2)
p.show()
Arity 1 or 2 - first or both parameters.
p = plot(x*cos(4*y), x*sin(4*y), y,
(-1, 1), (-1, 1))
p[0].surface_color = lambda a : a
p.show()
p[0].surface_color = lambda a, b : a*b
p.show()
Arrity of 3 will color by coordinates.
p[0].surface_color = lambda a, b, c : sqrt(a**2+b**2+c**2)
p.show()
