Can anyone suggest an elegant way to apply a function - in this case a
Style - to elements in a list.
In the example below I'm applying colours to their names. (I don't
know how Text is being used so I aimed to preserve the original
structure). As you can see it took me two lines to splice in the
colour styles. I thought I should have been able to do it in one, but
couldn't figure out how.
plabel = {Text["Orange", {10, 44}], Text["Blue", {10, 50}],
Text["Green", {2, 99}], Text["Red", {2, 20}]};
textColours = {Orange, Blue, Green, Red};
plabel2 =
Append[Transpose[Apply[{#1, #2} &, plabel, 1]], textColours];
plabel = Apply[Text[Style[#1, #3], #2] &, Transpose[plabel2], 1]
