Non mi visualizza la linea con le tabelle...
Salve ragazzi... premesso che sono ancora neofita di javascript e delle sue molteplici applicazioni... di seguito vi riporto il codice della pagina che ho intenzione id creare... la tabella a due colonne la prima colonne è il tempo la seconda i kw... quello che vorrei fare è crea un grafico che utilizzi come x la prima colonna e come y al seconda colonna. la curva sarà quindi una spezzata che unisce tutti i punti... Su un forum ho trovato finalmente la maniera per disegnare un segmento... Quando utilizzo il codice da solo e avvio con il browser mi da la linea tranqulliamente ... ma quando immetto il codice all'interno del file che contiene le tabelle... non mi compare più... come mai? potete aiutarmi. ( mi interessa solo far visualizzare il segmento)
