Hello

I am trying to use julia for my Linear Algebra and Multivariable Calculus courses that requires plotting, however I cannot seem to get the package to work. I have read all the other plotting post as well as stack overflow and other place, but I cannot seem to find a solution. I have updated packages and registers, built, removed, reinstalled, installed with other packages, precompiled packages and many other things but I cannot get it to work. Please can someone help. Your assistance would be greatly appreciated. Please see below program code and the error messages on my machine.

PROGRAM CODE: -------------

import Pkg;

Pkg.add(“Plots”);

using Plots;

f(x) = sin(x);

plot(f,0,2\*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

g(x) = cos(x);

# list of two functions f and g included in the plot

plot([f,g],0,2\*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

savefig(“firstgraph.pdf”);

Could you try the following code and report any output?

```julia
using Pkg
pkg"add GR_jll"
using GR_jll
Pkg.status()

```

Hello

It did not work. Please see below.

**CODE**  
I updated the code as follows:

"import Pkg;

Pkg.add(“Plots”);

Pkg.add(“GR\_jll”);

using GR\_jll;

using Plots;

Pkg.status()

f(x) = sin(x);

plot(f,0,2\*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

g(x) = cos(x);

# list of two functions f and g included in the plot

plot([f,g],0,2\*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

savefig(“firstgraph.pdf”);"

Probably a failed download.

Delete `C:\Users\Tshepho.julia\artifacts\c3712e14d6f387fa0a6d1509acbdd4b8976e87d1` manually, then run `using Pkg; pkg"instantiate"`, it should download the failing artifact again.

Try the solution I found here:

> [@Plots, InitError: UndefVarError: GR\_jll not defined](https://discourse.julialang.org/t/plots-initerror-undefvarerror-gr-jll-not-defined/102448):

ERROR: LoadError: InitError: UndefVarError: `GR_jll` not defined Stacktrace: [1] \_\_init\_\_() @ GR.GRPreferences ~/.julia/packages/GR/jehu0/src/preferences.jl:64

Basically, execute the following and then restart Julia:

```julia
Base.compilecache(Base.identify_package("GR"))

```
