Ciao vorrei creare, sono due giorni che ci provo, un grafico della curva di magnetizzazione con excel. Dovrebbe venire così:
Mentre a me viene tutt'altro.
V ( V ).....I (mA).......B (G)........H (As/m).........Z (Ω)..........µ r
1...........5,0..........1439,1.......2,45..............200,00........46772,0
2...........10,0........2878,3.......4,90..............200,00........46772,0
3...........14,0........4317,4.......6,86..............214,29........50112,9
4...........18,0........5756,6.......8,82..............222,22........51968,9
5...........22,0........7195,7.......10,78............227,27........53150,0
6...........25,0........8634,8.......12,25............240,00........56126,4
7...........28,0........10074,0.....13,72............250,00........58465,0
8...........32,0........11513,1.....15,68...........250,00.........58465,0
9...........35,0........12952,2.....17,15...........257,14.........60135,4
10.........41,0.........14391,4.....20,09...........243,90........57039,0
11.........47,0.........15830,5.....23,03...........234,04........54733,2
12.........59,0.........17269,7.....28,91...........203,39........47564,8
13.........92,0.........18708,8.....45,08...........141,30........33045,4
14.........227,0.......20147,9......111,22.........61,67..........14423,1
Questa è la scheda tecnica e da qui devo riuscire a fare l'immagine che vedete sopra.
Qualcuno sa dirmi come.
Grazie
