Epoch
Epoch est un moteur de création de graphiques et une bibliothèque de visualisation CSS-stylable conçus pour les données en temps réel et statistiques. Il fonctionne comme un outil de création de graphiques de séries temporelles qui rend les données historiques et en direct en utilisant un hybride de graphiques SVG et HTML5 Canvas pour maintenir les performances lors de mises à jour fréquentes.
La bibliothèque se distingue par un système de requête CSS unifié qui applique des styles aux éléments de tracé vectoriels et raster. Cela permet la résolution de thèmes visuels via des classes CSS et la capacité de personnaliser l'apparence de séries de données spécifiques à l'aide de feuilles de style.
L'ensemble d'outils couvre un large éventail de types de visualisation, y compris les graphiques en ligne, en aire, en barres et en cartes thermiques pour l'analyse des tendances, ainsi que des jauges, des graphiques en secteurs et des barres groupées pour les tableaux de bord. Il fournit également des capacités d'exploration statistique via des nuages de points et des histogrammes qui utilisent un regroupement par seaux discrets et un mélange de couleurs pour montrer la concentration des données.
Features
