From the following code
using MonteCarloMeasurements, Plots
x = LinRange(1:0.1:3)
a = 1 \pm 0.1
b = 2 \pm 0.3
f(x) = a*x + b
I obtained a plot with shaded area in light blue.
How can I change this color to, for example, gray or black color?
You can use the standard Plots.jl keywords, e.g.,
plot(x, f.(x), color=:gray)
plot(x, f.(x), fillcolor=:gray)
if you only want the shading to change color.
Thank you for your quick help. By the way, how can I increase the line width (or change the line style) of the mean line (curve)?
