Juniper Router interface throughput graphs?

Simplexity

I have been able to create a UnDP using the Juniper ifHCIn1SecRate (1.3.6.1.4.1.2636.3.3.1.1.7) for inbound traffic and another UnDP using the ifHCOut1SecRate (1.3.6.1.4.1.2636.3.3.1.1.8) for outbound traffic.  This is now displaying two separate graphs (one inbound and another outbound).  Is there a way to combine these into a single graph?

Thanks,

John
