Hi guys!
I have finished my implementation of my unit commitment problem and I would like to know if there is any possibility of including this kind of plot in my final results:
Extracted from: [Unit commitment - YALMIP](https://yalmip.github.io/example/unitcommitment/)
Basically right know I am accessing to my results as:
for j in 1:T
println("Dispatch Power in hour “,j,” = ", getvalue(p[:,j]))
println("Hour “, j, " Startup Cost =”,getvalue(s[:,j]))
end
But I would like to know if I there is any possibility of transforming the JuMP variable to a normal array o a dataframe in order to plot them.

Have you looked at [Gadfly.jl](https://github.com/GiovineItalia/Gadfly.jl)?

`getvalue` should work on `AbstractArray{JuMP.Variable}` directly, so there is no need to iterate over the elements. `getvalue` will give you an `AbstractArray{Float64}`, and at this point you can do absolutely anything with the data that you want.

Just check it, it works like charm thank you so much 😃

Hello ExpandingMan,
Thanks for this tips, however, I tried “println(“solved model results”, getvalue(::AbstractArray{JuMP.Variable}))” but it did not work for me. I keep get the following error; “ERROR: LoadError: MethodError: no method matching getvalue(::Type{AbstractArray{JuMP.Variable,N} where N})”
I have tried searching for this error, but not finding any meaningful help. I shall appreciate your insight regarding this issue. Thank you.

@ExpandingMan meant that instead of
```julia
for j in 1:T
println("Dispatch Power in hour ",j," = ", getvalue(p[:,j]))
println("Hour ", j, " Startup Cost =",getvalue(s[:,j]))
end
```
You can go
```julia
@show typeof(p) # Array{JuMP.Variable, 2}
px = getvalue(p)
@show typeof(px) # Array{Float64, 2}
sx = getvalue(s)
for j in 1:T
println("Dispatch Power in hour ",j," = ", px[:,j])
println("Hour ", j, " Startup Cost =", sx[:,j])
end
```

Thank you clarifying this for me! Have a great week.
