Fast iteration over rows of a DataFrame

[Marc.Cox]

Hi Rob @robsmith11 and all on this thread - might you have an insight or new approach here ?

So I took up the solution of using IndexedTables.jl for Fast Iterations over rows of a Dataframe
here. And then I proceeded to attempt to use IndexedTables for multidimensional 2D,3D (scatter) Plots
using IndexedTables to graph N-Dimensional data; but ran into issues trying to
collect the iterable for iter in eachindex(keys(tab_t1.index.columns))
because tab_t1.index.columns returns
ERROR: LoadError: type IndexedTable has no field index
as you’ll see when you run the Julia pseudocode listed here

Looking for ways to generalize using IndexedTables to Plot / Graph N-Dimensional data

Hi All, I’m looking for ways to generalize using IndexedTables to graph N-Dimensional data, but I’m stuck on how to collect the “for iter in eachindex(keys(tab_t1.index.columns))”. In that regard, would you please see MWE pseudocode snippet below and let me know any suggestions you might have ? using IndexedTables using Plots # 2D = 1Dy Dependent var equation of 1Dx INDependent var tab_t1 = table( (x=1:5, y=randn(5)); pkey = [:x] ) str_current_equation_approximated = "(x=1:5, y=randn(5))" …

Any new insights or approaches to getting the keys from tab_t1.index.columns ;
-or- another way to automatically graph general multidimensional 2D,3D,(? and 4D like www.wolframalpha.com ?) scatter Plots is appreciated.

TY
