Node.js plotly package

plotly is a package that works differently to most. To use their software, you must register with a username and be provided an API key (at https://plot.ly/). You then place the username and API key in your script. At that point you can use all of the plotly features.

Firstly, like other packages, we need to install it:

npm install plotly

Once installed, we can reference the plotly package as needed. Using a simple script, we can generate a histogram with plotly:

//set random seed
var seedrandom = require('seedrandom');
var rng = seedrandom('Jupyter');
//setup plotly
var plotly = require('plotly')(username="<username>", api_key="<key>")
var x = [];
for (var i = 0; i < 500; i ++) {
    x[i] = Math.random();
}
require('plotly')(username, api_key);
var data = [
  {
    x: x,
    type: "histogram"
  }
];
var graphOptions = {filename: "basic-histogram", fileopt: "overwrite"};
plotly.plot(data, graphOptions, function (err, msg) {
    console.log(msg);
})...
