Making Graphs

The Frappe UI Graph object enables you to render simple line, bar or percentage graphs for single or multiple discreet sets of data points. You can also set special checkpoint values and summary stats.

Example: Line graph

Here's an example of a simple sales graph:

	// Data
	let months = ['August, 2016', 'September, 2016', 'October, 2016', 'November, 2016',
		'December, 2016', 'January, 2017', 'February, 2017', 'March, 2017', 'April, 2017',
		'May, 2017', 'June, 2017', 'July, 2017'];

	let values1 = [24100, 31000, 17000, 12000, 27000, 16000, 27400, 11000, 8500, 15000, 4000, 20130];
	let values2 = [17890, 10400, 12350, 20400, 17050, 23000, 7100, 13800, 16000, 20400, 11000, 13000];
	let goal = 25000;
	let current_val = 20130;

	let g = new frappe.ui.Graph({
		parent: $('.form-graph').empty(),
		height: 200,					// optional
		mode: 'line',					// 'line', 'bar' or 'percentage'

		title: 'Sales',
		subtitle: 'Monthly',

		y: [
			{
				title: 'Data 1',
				values: values1,
				formatted: values1.map(d => '$ ' + d),
				color: 'green'		// Indicator colors: 'grey', 'blue', 'red',
							// 'green', 'light-green', 'orange', 'purple', 'darkgrey',
							// 'black', 'yellow', 'lightblue'
			},
			{
				title: 'Data 2',
				values: values2,
				formatted: values2.map(d => '$ ' + d),
				color: 'light-green'
			}
		],

		x: {
			values: months.map(d => d.substring(0, 3)),
			formatted: months
		},

		specific_values: [
			{
				name: 'Goal',
				line_type: 'dashed',	// 'dashed' or 'solid'
				value: goal
			},
		],

		summary: [
			{
				name: 'This month',
				color: 'orange',
				value: '$ ' + current_val
			},
			{
				name: 'Goal',
				color: 'blue',
				value: '$ ' + goal
			},
			{
				name: 'Completed',
				color: 'green',
				value: (current_val/goal*100).toFixed(1) + "%"
			}
		]
	});

bar mode yeilds:

You can set the colors property of x to an array of color values for percentage mode:

You can also change the values of an existing graph with a new set of y values:

	setTimeout(() => {
		g.change_values([
			{
				values: data[2],
				formatted: data[2].map(d => d + 'L')
			},
			{
				values: data[3],
				formatted: data[3].map(d => d + 'L')
			}
		]);
	}, 1000);
