coconut-graph

Quick and dirty reusable timeseries graphs with d3, developed to visualize usage.

Currently supports line, bar, scatter.

Depends heavily on JSON structure used in the coconut wepapp:

{
	"meta": {
		"period": "day",
		"urls": {
			"next": "<url to get json for the next day>",
			"previous": "<url to get json for previous day>"
		},
		"readable_interval": "15 minuten"
	},
	"data": {
		"keys": ["timestamp", "amount"],
		"extents": ["2015-05-29T00:00:00", "2015-05-29T23:59:59"],
		"values": [
			["2015-05-29T14:00:00", 50],
			["2015-05-29T14:15:00", 0],
			["2015-05-29T14:30:00", 5],
			["2015-05-29T15:00:00", 6]
		],
		"slices": 96
	}
}

var Loader = require('coconut-graph').Loader;
var url = '/graph-data.json'; // url to above json

var graph = new Loader(url, {
	graphs: [{
		container: 'container',
		plot: { type: 'bar', key: 'amount', label: 'verbruik [l]'}
	}]
});

// Loads the data for the next day, url defined in meta.urls
graph.load_url('next');

// previous day
graph.load_url('previous');
