isoline
(isoline [f x-min : float x-max : float y-min : float y-max : float samples : int level : float style : int label : cstr] :)
draw a single f(x,y)=level contour.
defn
contours
(contours [f x-min : float x-max : float y-min : float y-max : float samples : int n : int styles : int label : cstr] :)
draw multiple automatically spaced contour levels.
defn
contour-intervals
(contour-intervals [f x-min : float x-max : float y-min : float y-max : float samples : int n : int fills : int label : cstr] :)
fill contour bands using sampled cells.
defn
color-field
(color-field [f x-min : float x-max : float y-min : float y-max : float samples : int alpha : float] :)
color sampled cells by f(x,y)->color-idx.
