Plotting three multivariable user defined functions on one graph

I have three functions that I created and I want to place them all on one graph. Each function has a couple variables that are defined within a data file. I can plot one function at a time fine, but I am having trouble getting them all to be on one graph.

I am using fplot to plot my functions(not sure if there is an easier way)

fplot(@Fn1,[-10,10],[],[],[],a,b,e)
fplot(@Fn2,[-10,10],[],[],[],c,f)
fplot(@Fn3,[-10,10],[],[],[],d,g)

It should look something like this when its all said and done. http://screencast.com/t/4EIecQmr

Thank you for your time.
