A continuación he mencionado 4 archivos xml en los que tengo estado y clave y BuildDate. Necesito representar la información de "estado" de "clave" en un gráfico basado en BuildDate.

El eje x debe tener más de 6 días (w.r.t fecha actual. Supongamos que hoy es el 7 de septiembre, entonces la entrada debe ser del 1 al 6 de septiembre). Si hay una entrada para la fecha correspondiente en BuildDate feild, entonces el estado debe mostrarse en rojo o verde (Fallido - rojo, Éxito - verde). De lo contrario, se debe mostrar el negro.

Principalmente estoy luchando para agregar el valor y mostrar de acuerdo a la fecha.

¿Cómo puedo hacer esto a través de jfreechart? (StackedBarChart?)
