My code to plot with Latex features is,

rc(“text”, usetex=true)  
rc(“font”, family=“serif”)

# Plot

errorbar(ω, A, yerr=ΔA, fmt=“.”, label=“Messdaten”)  
plot(ω, model(ω, γ), label=“Fit”)

title(“Schwingungsamplitude vs. Motorfrequenz”)  
xlabel(L"Motorfrequenz \omega“)  
ylabel(L"Schwingungsamplitude A”)  
legend()

savefig(“Schwingungsamplitude.pdf”)

While executing this code, I get this error (a huge one ☹),  
PyError ($(Expr(:escape, :(ccall(#= C:\Users\Purvaash.julia\packages\PyCall\zqDXB\src\pyfncall.jl:43 =# @pysym(:PyObject\_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) \<class ‘RuntimeError’\>

I followed the following discussion: [https://stackoverflow.com/questions/58121461/runtimeerror-failed-to-process-string-with-tex-because-latex-could-not-be-found](https://stackoverflow.com/questions/58121461/runtimeerror-failed-to-process-string-with-tex-because-latex-could-not-be-found) and installed Latex, dvipng and Ghostscript. Also added the executables to path. But still get the error. Moreover added the following package on Julia: Pkg.add(“PGFPlotsX”) while following instructions from here: “[Installation · Plots](https://docs.juliaplots.org/latest/install/)” (not sure if this is required though).

Any helps/tips/suggestion?
