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

Please provide a working example of your code, including any packages you are using

Please follow the recommended guidelines to post your code

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

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.
