Hi,

I am using the Plots.jl with the GR backend. I am trying to make the following plot:

plot( SSE[1].Mag, SSE[1].N )

Where both SSE[1].Mag and SSE[1].N are of types Array{Any,1}

However, I am getting the error below. I would appreciate if someone could help me finding out the issue. If possible, please send along any documentation to understand better my mistake.

thank you

Hi,  
please post a reproducible example, e.g. do you get this with `plot(rand(100),rand(100))`? What is your version number of Plots?
