Question:

How to show all Callout labels?

expr = Uncompress[FromCharacterCode[
    Flatten[ImageData[Import["https://i.stack.imgur.com/Pva9y.png"], "Byte"]]]];
ListLinePlot[expr, PlotRange -> All,ImageSize -> 1000]

As we see, it just 4 Callout labels? But how to show all Callout labels?

xy = MapIndexed[{#2[[1]], #} &, expr];

data1 = Cases[{p_, Callout[a_, b__]} :> Callout[{p, a}, b]] @ xy;

data2 = xy /. Callout -> (# &);

Show[ListLinePlot[data2], ListPlot[data1], ImageSize -> 800]
