for (var i = 0; i &lt; 50; i ++) {
	y0[i] = Math.random();
	y1[i] = Math.random() + 1;
}

require('plotly')(username, api_key);

var trace1 = {
  y: y0,
  type: "box"
};
var trace2 = {
  y: y1,
  type: "box"
};
var data = [trace1, trace2];
var graphOptions = {filename: "basic-box-plot", fileopt: "overwrite"};
plotly.plot(data, graphOptions, function (err, msg) {
    console.log(msg);
});

Box Plot That Displays the Underlying Data

require('plotly')(username, api_key);

var data = [
  {
    y: [0, 1, 1, 2, 3, 5, 8, 13, 21],
    boxpoints: "all",
    jitter: 0.3,
    pointpos: -1.8,
    type: "box"
  }
];
var graphOptions = {filename: "box-plot-jitter", fileopt: "overwrite"};
plotly.plot(data, graphOptions, function (err, msg) {
    console.log(msg);
});

Grouped Box Plot
