合并d3.js中的排列

Question

我的elex.csv采用此格式

"CONUM","PIXPMK","PIXMAR"

"1","461","436"
"2","398","428",
"3","447","436"

我想要这种格式的数据集 -

var dataset1 = [ [1, 417], [1, 436], [2, 398], [2, 428], [3, 447], [3, 436]];

我曾多次尝试过以这种形式从csv获取数据，但都是徒劳的。我附上了我的代码

var dataset1 = [];

d3.csv("elex.csv", function(data) {
   dataset1 = data.map(function(d) { return [ [+d["CONUM"], +d["PIXMAR"]],[+d["CONUM"],+d["PIXPMK"]]]; });
console.log(dataset1)
});

这会将dataset1作为

返回

[[[1,417],[1,436]],[[2,398],[2,428]]]

Answer 1

迭代每个元素，并将第一部分和第二部分分别推入dataset1：

dataset1 = [];
d3.csv("elex.csv", function(data) {
  data.forEach(function(d) {
    dataset1.push([d['CONUM'], d['PIXMAR']]);
    dataset1.push([d['CONUM'], d['PIXPMK']*100])
  });
  console.log(dataset1);
});
