Bonjour,

J'utilise un fichier HTML, qui exécute du JavaScript, et qui me génère ceci:

Nom : Capture d’écran 2017-06-04 à 17.25.06.png Affichages : 217 Taille : 224,4 Ko
Nom : Capture d’écran 2017-06-04 à 17.25.35.png Affichages : 170 Taille : 256,2 Ko
Nom : Capture d’écran 2017-06-04 à 17.25.53.png Affichages : 159 Taille : 62,8 Ko

J'aimerais optimiser l'affichage et exploiter les valeurs des 2 colonnes ( TWA et HDG ), à savoir créer 2 nouvelles colonnes nommées TWA Moy et HDG Moy qui listerait la valeur moyenne de la ligne par rapport à la première ( ce qui me permettrait de "lisser" les itérations )

En image ça donne ceci :

Nom : Capture d’écran 2017-06-04 à 17.36.52.png Affichages : 218 Taille : 214,0 Ko
Nom : Capture d’écran 2017-06-04 à 17.37.23.png Affichages : 245 Taille : 190,7 Ko

J'ai la contrainte d'avoir 2 amures ( Tribord en Vert et Bâbord en Rouge ) dans le code source de la page les valeurs TWA sont positives pour les valeurs en Vert et négatives pour les valeurs en Rouge donc une distinction pour arrêter le calcul de la moyenne est possible.
Concernant les valeurs HDG elle doivent également s'arrêter à un changement d'amure.

Je ne sais pas s'il est possible de créer l'espace entre Vitesse Bateau et TWA Moy ...
Et le saut de ligne dépends des fichiers météo qui ont pour heures fixes 02h / 05h / 08h / 11h / 14h / 17h / 20h / 23h

Voici le code source de la page exploitée:
