Plotly.js
Plotly.js est une bibliothèque de graphiques qui contient plus de 40 types de graphiques, des graphiques 3D, des graphiques statistiques et des cartes SVG.
Nuages de points
Code source
var xArray = [50,60,70,80,90,100,110,120,130,140,150];
var yArray = [7,8,8,9,9,9,10,11,14,14,15];
// Define Data
var data = [{
x: xArray,
y: yArray,
mode:"markers",

}];
// Define Layout
var layout = {
xaxis: {range: [40, 160], title: "Square Meters"},
yaxis: {range: [5, 16], title: "Price in Millions"},
title: "House Prices vs. Size"
};
Plotly.newPlot("myPlot", data, layout);

Diagramme à barres
Code source
var xArray = ["Italy","France","Spain","USA","Argentina"];
var yArray = [55, 49, 44, 24, 15];
var data = [{
x: xArray,
y: yArray,
type: "bar"
}];
var layout = {title:"World Wine Wine Production"};
Plotly.newPlot("myPlot", data, layout);
Graphiques à barres horizontales
Code source
var xArray = [55, 49, 44, 24, 15];
var yArray = ["Italy","France","Spain","USA","Argentina"];
var data = [{
x: xArray,
y: yArray,
type: "bar",
orientation: "h"
}];
var layout = {title:"World Wine Wine Production"};
Plotly.newPlot("myPlot", data, layout);
Camemberts
Pour afficher un camembert au lieu de barres, remplacez x et y par des étiquettes et des valeurs, et changez le type en « camembert » :
var data = [{
labels: xArray,
values: yArray,
type: "pie"
}];
Graphiques en anneau
Pour afficher un beignet au lieu d'une tarte, ajoutez un trou :
var data = [{
labels: xArray,
values: yArray,
hole: .4,
type: "pie"
}];
Tracer des équations
Code source
var exp = "Math.sin(x)";
// Generate values
var xValues = [];
var yValues = [];
for (var x = 0; x <= 10; x += 0.1) {
yValues.push(eval(exp));
xValues.push(x);
}
// Display using Plotly
var data = [{x:xValues, y:yValues, mode:"lines"}];
var layout = {title: "y = " + exp};
Plotly.newPlot("myPlot", data, layout);
