the same solution!
Hi Kuhu,
Try this solution:
var dataset1 = [];
d3.csv("elex.csv", function(data) {
data.forEach(function(d) {
dataset1.push([+d.CONUM, +d.PIXMAR]);
dataset1.push([+d.CONUM, +d.PIXPMK]);
});
console.log(dataset1);
});
map
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map>
gives
one entry per input row, but since you want two output entries per input
row, you can use forEach
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach>
to
execute a function for each input row that creates the two output entries
and adds them to dataset1.
All the best,
Curran
