transforming a d3.csv function to process an array instead

I'm just getting started with d3 and have what might be a simple question. I've been working on creating a graph using CSV data, but now I want to achieve the same result with array data instead.

somevariable = d3.csv(ds, function(da) {
  da.forEach(function(d) {
    d.date = f.parse(d.date);
    d.value = +d.value;
  });
 do more functions ()....
});

I need to figure out how to parse array data and use it in my code, similar to how I've been doing with d3.csv. I keep encountering an error when trying to parse d.date using the t.slice format, even though it works fine with CSV data. Any help on this issue would be greatly appreciated.

Answer №1

Here's an example that utilizes an array for parsing dates:

var convertDate = d3.time.format("%Y-%m-%d").parse;

var dataArr = [
  ["2017-05-15", 250],
  ["2017-06-20", 400],
  ["2017-09-10", 150]
];

// Transform the array into the desired format for D3
var formattedData = dataArr.map(function(item) {
    return {
      date: convertDate(item[0]),
      value: item[1]
    };
});
