It is not a matter of an answer, but of a short comment: not PlotLabels but PlotLabel and everything works.
But just to make this answer more useful, you may check this as follows:
Options[ListLinePlot]
{AlignmentPoint -> Center, AspectRatio -> 1/GoldenRatio, Axes -> True,
AxesLabel -> None, AxesOrigin -> Automatic, AxesStyle -> {},
Background -> None, BaselinePosition -> Automatic, BaseStyle -> {},
ClippingStyle -> None, ColorFunction -> Automatic,
ColorFunctionScaling -> True, ColorOutput -> Automatic,
ContentSelectable -> Automatic, CoordinatesToolOptions -> Automatic,
DataRange -> Automatic, DisplayFunction :> $DisplayFunction,
Epilog -> {}, Filling -> None, FillingStyle -> Automatic,
FormatType :> TraditionalForm, Frame -> False, FrameLabel -> None,
FrameStyle -> {}, FrameTicks -> Automatic, FrameTicksStyle -> {},
GridLines -> None, GridLinesStyle -> {}, ImageMargins -> 0.,
ImagePadding -> All, ImageSize -> Automatic,
ImageSizeRaw -> Automatic, InterpolationOrder -> None,
Joined -> True, LabelStyle -> {}, MaxPlotPoints -> \[Infinity],
Mesh -> None, MeshFunctions -> {#1 &}, MeshShading -> None,
MeshStyle -> Automatic, Method -> Automatic,
PerformanceGoal :> $PerformanceGoal, PlotLabel -> None,
PlotLegends -> None, PlotMarkers -> None, PlotRange -> Automatic,
PlotRangeClipping -> True, PlotRangePadding -> Automatic,
PlotRegion -> Automatic, PlotStyle -> Automatic,
PlotTheme :> $PlotTheme, PreserveImageOptions -> Automatic,
Prolog -> {}, RotateLabel -> True, TargetUnits -> Automatic,
Ticks -> Automatic, TicksStyle -> {}}
and then find the option you ar5e looking for (and sometimes also the one you never thought of).
Have fun!
PlotRange, reporting it. – rcollyer Mar 27 '16 at 17:16PlotLabels, see e.g.LogPlot[{0, 0.1}, {t, 0, 1}, PlotLabels -> Automatic],Plot[0, {t, 0, 1}, PlotRange -> {{0, 1}, {.001, All}}, PlotLabels -> All]. Reported them and TechSupport has filed it internally. – István Zachar Mar 29 '16 at 15:34Placed[ lbl, pos ]will work, if pos is different fromAutomatic. In the given example this will work:ListLinePlot[{1, 1, 2, 3, 5, 8}, PlotRange -> {All, {5.5, 6}}, PlotLabels -> Placed[1, {0.9, 0.7}]]where the position specs are relative fractions of the plot's region. – gwr Apr 22 '16 at 11:07PlotLabelwithout thesat the end? – Sumit Jun 19 '16 at 13:25Placedworkaround is not robust enough, see e.g.LogPlot[{0, 0.1}, {t, 0, 1}, PlotLabels -> Placed[{"A", "B"}, Above]]. – István Zachar Jul 25 '16 at 18:03PlotLegendsdid the trick. – Rainer Glüge Dec 01 '22 at 09:05
