electron-chartjs v1.0.0

Render chart.js charts using electron

Leverage chart.js and electron features for quick visualisations.

This modules just proxies options to chart.js constructor.

See chart.js documentation for options.

Installation

npm i electron-chartjs

Usage

The only difference from chart.js constructor - you need to skeep context argument.

Simple barchart:

const chart = require('electron-chartjs')
chart({
	type: 'bar',
	data: {
		labels: ['a', 'b', 'c', 'd'],
		datasets: [{
			label: 'red bars',
			backgroundColor: '#ab1020',
			data: [0, 3, 4, 1],
		}],
	}
})

will render window with barchart.

For more charts check chart.js docs

Why?

To reduce number of actions you need to perform for visualizing data from database using js.

No need to setup client + server to render some charts with js.

Example:

const usersByAge = await knex.raw(`
	select age, count(age) as count
	from users
	group by age
`)
const labels = _.map(usersByAge, 'age')
const data = _.map(usersByAge, 'count')
chart({
	type: 'bar',
	data: {
		labels,
		datasets: [{
			label: 'users by age',
			backgroundColor: '#bada55',
			data,
		}],
	},
})
