Node.js plotly package

plotly is a package that works differently to most. To use this software, you must register with a username so that you are provided with 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 package features.

First, like all of the 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...
