Bonjour,
je programme en python
je recupere le tableau periode et je souhaite affiche la courbe correspondante:
periode=[]
j=0
for j in range(z):
periode.append([])
p=0
m=0
for m in range(z-1):
periode[m]=tabkfloat[m+1] - tabkfloat[m]
print periode[m]
subplot(211)
plot(periode)
show()
periode s'affiche comme ca:
11
11
10
12
17
19
17
12
10
10
10
10
13
18
19
15
12
10
10
10
10
14
19

j'obtiens l'erreur suivante:

que dois je faire pour pouvoir afficher ma courbe??
