How do I convert two series for plotting?

Hi Fred,

The elements of hList and TList are strings. They need to be converted to numeric before plotting. One way to do that

ListLogPlot[Interpreter["Number"] /@ {hList, TList},
 PlotRange -> All,
 PlotLegends -> {"hList", "TList"}]

Rphit,
Thank you very much! I will make use of this solution on many issues later.
