How is it possible to map a list of Tooltip values to the functions being plotted?

For example: Assume, f1[x], f2[x], f3[x]... are functions defined. {t1, t2, t3, ...} are the list of tool-tips to display.

Then to plot: Plot[ Tooltip[{f1[x], f2[x], ... }], {x, a, b}]; Which will just display the functions as tool-tip OR Plot[ {Tooltip[f1[x], t1], Tooltip[f2[x], t2], ...... }, {x, a, b}]

Which is the required behavior, but, is there another shorter or direct way of mapping the functions f1, f2, f3, ... to t1, t2, t3, .... rather than manually?

funcs = {Sin[x], Cos[x], Sin[x] Cos[x]};
tips = {"t1", "t2", "t3"};

Plot[Thread[Tooltip[funcs, tips]], {x, -2 Pi, 2 Pi}, Evaluated -> True]
Plot[Evaluate@Thread[Tooltip[funcs, tips]], {x, -2 Pi, 2 Pi}]
Plot[Evaluate@MapThread[Tooltip, {funcs, tips}], {x, -2 Pi, 2 Pi}]
Plot[Tooltip @@@ Transpose[{funcs, tips}], {x, -2 Pi, 2 Pi}, Evaluated -> True]

all give

  • $\begingroup$ I've never seen the Evaluated option before. Is it undocumented? $\endgroup$

  • $\begingroup$ @2012rcampion, it is undocumented as of version 9.0.1.0; don't know if version 10 has it documented. See other appearances of Evaluated on this site $\endgroup$
