javascript - concec.js 中 Conrec.contour 的参数是什么？

Question

我正在尝试使用 d3.js 和 conrec.js 构建等高线图

在 Jason 的示例代码中 conrec.js , 我无法插入 Conrec 对象的 contour() 属性的每个参数应该是什么。这是他来自 github README 的例子:

var data = [[0, 1, 0], [1, 2, 1], [0, 1, 0]];
var c = new Conrec;
c.contour(data, 0, 2, 0, 2, [1, 2, 3], [1, 2, 3], 3, [0, 1, 2]);
// c.contours will now contain vectors in the form of doubly-linked lists.
// c.contourList() will return an array of vectors in the form of arrays.

在一般情况下，c.contour 的参数应该是什么还不清楚，因为零和二的语义在这里重载了。

我可以得到每个论点的一般描述吗？

这是源代码中的文档在这里 https://github.com/jasondavies/conrec.js/blob/master/conrec.js :

/**
   * contour is a contouring subroutine for rectangularily spaced data
   *
   * It emits calls to a line drawing subroutine supplied by the user which
   * draws a contour map corresponding to real*4data on a randomly spaced
   * rectangular grid. The coordinates emitted are in the same units given in
   * the x() and y() arrays.
   *
   * Any number of contour levels may be specified but they must be in order of
   * increasing value.
   *
   *
   * @param {number[][]} d - matrix of data to contour
   * @param {number} ilb,iub,jlb,jub - index bounds of data matrix
   *
   *             The following two, one dimensional arrays (x and y) contain
   *             the horizontal and vertical coordinates of each sample points.
   * @param {number[]} x  - data matrix column coordinates
   * @param {number[]} y  - data matrix row coordinates
   * @param {number} nc   - number of contour levels
   * @param {number[]} z  - contour levels in increasing order.

  Conrec.prototype.contour = function(d, ilb, iub, jlb, jub, x, y, nc, z) {
