Hi,
In Makie I can plot two linear lines with the code
x = LinRange(0,100,101)
f = Figure();
ax = Axis(f[1,1])
lines!(x, 30 .+ 0.6*x, color = :blue, label = "Lower")
lines!(x, 2 .+ 1.1*x, color = :blue, label = "Upper")
f
Which produces
How do I shade the region between two lines? I have looked around however could not find anything 
Thanks,
Harry
Is this good enough?
x = LinRange(0,100,101)
y1 = 30 .+ 0.6*x
y2 = 2 .+ 1.1*x
f = Figure();
ax = Axis(f[1,1])
lines!(x, y1, color = :blue, label = "Lower")
lines!(x, y2, color = :blue, label = "Upper")
band!(x, min.(y1, y2), max.(y1, y2), color=:gray)
f
That looks great however it appears to not be translating to my specifc example below.

Not sure what is going on here?
I am pretty sure it is because Rx is not sorted:
x = [1, 5, 2] # NOT sorted
y1 = 2 * x
y2 = -2 * x
f = Figure()
ax = Axis(f[1,1])
lines!(x, y1, color = :blue, label = "Upper")
lines!(x, y2, color = :blue, label = "Upper")
band!(x, min.(y1,y2), max.(y1,y2), color=:gray)
It works when sorted:
x = [1, 2, 5] # sorted
y1 = 2 * x
y2 = -2 * x
f = Figure()
ax = Axis(f[1,1])
lines!(x, y1, color = :blue, label = "Upper")
lines!(x, y2, color = :blue, label = "Upper")
band!(x, min.(y1,y2), max.(y1,y2), color=:gray)
Exactly the solution, thanks for the help!
the fillrange keyword of the plot() function produces a result similar to this
using Plots; gr()
x = LinRange(0,100,101)
yL(x)=30 .+ 0.6*x
yU(x)=2 .+ 1.1*x
plot(x,yL, color = :black, label = "Lower")
plot!(x, yU, color = :blue, label = "Upper")
plot!(yL,25,75, label="", fillrange=yU,fillalpha=0.3, fillcolor=:red)
