The program has run ,but the scatter diagram does not show ,why?  
Is it too much data in my code?

Three suggestions:

1. See this [stackoverflow question/answer](https://stackoverflow.com/questions/62146901/how-to-display-julia-gadfly-plot-in-atom-editor). Test the plot in that example.
2. Read the [DataFrames tutorial](http://juliadata.github.io/DataFrames.jl/stable/man/getting_started/#Taking-a-Subset-1), to fix up the DataFrames warnings (the warnings do give you a hint)
3. You don’t the `Plots` package in the first line, just `Gadfly` should be fine (the 2 are separate plotting packages)
