Plot grids with Plots and Gadfly

I need a figure with components from Plots and Gadfly, specifically Plots.heatmap() and Gadfly.plot().

The following does not work:

using Plots,Gadfly,Compse
p1 = Plots.heatmap(rand(10,10))
p2 = Gadfly.plot(x=[1,2,3], y=[6,7,8])
vstack(p1,p2)

ERROR: MethodError: no method matching vstack(::Plots.Plot{Plots.GRBackend}, ::Plot)
Closest candidates are:
  vstack(::Any, ::Any, ::Any, ::Tuple{Context,Compose.HAlignment}...) at /home/me/.julia/packages/Compose/Opbga/src/stack.jl:81

i don’t think it’s possible to mix Gadfly and Plots. might try using Gadfly.spy() instead of Plots.heatmap().
