hacer graficas de barras y lineas con rangos en java con librerias jfreechart-1.0.14

bueno les mostrare como crear una aplicacion en el cual ustedes las puedan nesesitar para hacer graficas de barras y lineas por ejemplo encuestas ó presentaciones primero creamos una clase llamada

CombinedCategoryPlotDemo1 y en esa clase ponemos el siguiente codigo:

import java.awt.Font;

import javax.swing.JPanel;

}

luego de esto descargamos el siguiente pakete de librerias descarga adentro ay 3 librerias las agregas y listo les dejo una imagen para visualizar como quedan las graficas
