Julia not able to convert Array to a series data for plotting

Hmmm. I tried for 20 minutes to replicate your problem but I couldn’t. Part of it is because you use many packages that are not in your snippet. This made me have to investigate what packages I needed to install to be able to run every line. After discovering that I had to install and use Arrow.jl, CSV.jl, and Parquet.jl, I stopped looking because there are further packages I need to install to get to the point of your error. I advice to take a look at PSA: make it easier to help you for advice on how to paste a minimal working example, it would be easier to reproduce your error and help.
Ideally we should be able to copy and paste your snippet and it should throw the error.
