After creating an association of time series as follows:
stocks = {"AAPL", "FB"};
prices = FinancialData[stocks, {{2019, 11, 1}, {2019, 11, 15}}];
stockPrices = AssociationThread[stocks, prices];
I plot with:
DateListPlot[Tooltip[stockPrices]]
Unfortunately I cannot figure out how to format the dates in the tooltip in a more conventional form, e.g. mm/dd/yy.
Also, how can one create tooltips with just the value, excluding the date. The documentation for Tooltip is pretty thin.
DateListPlot[Tooltip[stockPrices]] /. Tooltip[pt_, {date_, price_}] :> Tooltip[pt, {DateString[ DateList@date, {"Month", "/", "Day", "/", "YearShort"}], price}]
