Mi problema es en:
JFreeChart Grafica;
Serie.add(0,0);
Coleccion.addSeries(Serie);
Grafica = ChartFactory.createXYLineChart("Voltaje vs Frecuencia", "Voltaje", "Frecuencia", Coleccion,
PlotOrientation.VERTICAL, true, true, false);
que queda sin ningun cambio en el compilador.
que es lo que le puede pasar??
Esperando su gran ayuda.
Gracias
