Plotly is a free and open-source graphing library for JavaScript. We recommend you read our Getting Started guide for the latest installation or upgrade instructions, then move on to our Plotly Fundamentals tutorials or dive straight in to some Basic Charts tutorials.

Basic Example

var trace1 = {
		x: [0, 1, 2, 3, 4, 5, 6, 7, 8],
		y: [0, 3, 6, 4, 5, 2, 3, 5, 4],
		type: 'scatter',
		name:'Plot 1'
        };
var trace2 = {
	    x: [0, 1, 2, 3, 4, 5, 6, 7, 8],
	    y: [0, 4, 7, 8, 3, 6, 3, 3, 4],
	    type: 'scatter',
	    name:'Plot 2'
        };
var trace3 = {
	    x: [0, 1, 2, 3, 4, 5, 6, 7, 8],
	    y: [0, 5, 3, 10, 5.33, 2.24, 4.4, 5.1, 7.2],
	    type: 'scatter',
	    name:'Plot 3'
        };

var data = [trace1, trace2, trace3];
var layout = {
		showlegend: true,
		legend: {"orientation": "h"}
	    };
 
Plotly.newPlot('myDiv', data, layout);
