[amibroker] How do we plot the Yield Curve in Amibroker?

[Gregory G. Serevetas]

Any help on this will be very greatly appreciated.

Also, if you could tell me how to plot futures spreads (such as the 
FITE, 5 year over 10 year, and the NOB, ten year over 30 year) I will 
greatly appreciate it.  Thanks
