Error in plotting the graph

New to Julia

Hello
I am trying to excecute the program but facing the issue only when i am trying to plot the fucntion,
//my program
n_samples = 15
lower_bound = 0
upper_bound = 14/15
x = sample(n_samples, lower_bound, upper_bound, SobolSample())
f = x->exp(xcos(3(22/7)*x))
y = f.(x)
scatter(x, y, label=“Sampled Points”, xlims=(lower_bound, upper_bound), legend=:top)
plot!(x,y, scatter(x, y, label=“Sampled Points”, xlims=(lower_bound, upper_bound), legend=:top))

//error iam getting
MethodError: no method matching Plots.Plot{Plots.GRBackend}(::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char, ::Char)

Hello and welcome. First of all, you should provide minimal working examples (you were missing the include/using statements to make it self-contained) and format code properly: to enable proper highlighting, you should enclose code in backticks `.

Single backticks like `Code` will appear as code for inline use. Longer sections should be included in triple backticks:

```julia
Some very
Long code
Here
```

Will appear as:

Some very
Long code 
Here

In terms of the original question:

This line looks odd. There’s a scatter inside a plot, both with x and y provided, although I don’t know if plot does that, it takes lots of things without complaining.
