Reactance charts were a dime a dozen (free, actually) and appeared as regular features in electronics magazines in the days before smartphone apps provided ready access to reactance versus frequency calculations. This one was in the May 1959 issue of Electronics World. Calculators are nice and indispensible in design work, but sometimes having "the big picture" of how various values of inductance and capacitance "react" with changes in applied frequency is often useful - especially if you are a newcomer to electronics. To paraphrase a popular saying, "A reactance chart is worth a thousand calculators."
