mise en forme de donnees

bonjour

j'ai un tableau mat200min200

Code:

[ 74.03571429 73.94886364 73.87012987 73.79951299 73.73701299 73.68262987 73.63636364 73.59821429 73.56818182 73.54626623 73.53246753 73.52678571 73.52922078 73.53977273 73.55844156 73.58522727 73.62012987 73.66314935 73.71428571 73.77353896 73.84090909 73.9163961 74. 74.09172078 74.19155844 74.29951299 74.41558442 74.53977273 74.67207792 74.8125 74.96103896 75.11769481 75.28246753 75.45535714 75.63636364 75.82548701 76.02272727 76.22808442 76.44155844 76.66314935 ]

pour traiter ces donnees j'ecris

Code:

---

var conv_mat200min200 = mat200min200.split(" ");

---

le probleme est que je ne peux relire css donnees car je recupere

Code:

---

[,,74.03571429,,,73.94886364,,,73.87012987,,,73.79951299,,,73.73701299,,,73.68262987,,,73.63636364,,,73.....

pourquoi y a t il trois virgules apres chaque valeur ??

Parce qu'il doit y avoir trois espaces entre chaque valeur...

et comment fait on si je veux recuperer ces donnees avec seulement deux virgules separant les valeurs au lieu de trois ?

:recherch:

Soit en indiquant explicitement ces trois espaces

Code:

---

var conv_mat200min200 = mat200min200.split(" ");

---

soit en utilisant une expression régulière

Code:

---

var conv_mat200min200 = mat200min200.split(/\s+/);

---

en ecrivant

Code:

---

var conv_mat200min200 = mat200min200.split(" ");

---

je recupere

Code:

C'est-à-dire ? Quel est le but final souhaité ?

les donnees proviennent de calculs de polynomes de regression effectues dans une fonction python

j'utilise ces donnees pour tracer un graphe du polynome avec le plugin Flot

Ces données sont des String ! A mon avis, il faut les transformer en Number (avec Math.parseFloat) pour que Flot puisse traiter les données. A moins que ce plugin gère ça automatiquement, je n'ai pas vérifié.

Attention aux données "vide" (chaines "" dans ce cas dû au split ou à la chaine fournie en entrée).
