How can I align the legend to their lifespan bars?

  • $\begingroup$ I suspect that this is going to be difficult if you use standard legending. (I might be wrong.) I would build the legend by hand as a Graphics objects and specify the coordinates to match the plot. Then the task is to align the legend with the plot, which can be accomplished either by using Row and setting the ImageMargin on the top and bottom by hand (to make sure they're the same on the legend and the plot) or I would use a package like SciDraw. SciDraw is great but takes time to learn. I do hope someone will post an easier solution though ... $\endgroup$

Use the individual legends as tick labels:

dates = Through[{First, Last}@#] & /@ res

{{1769, 1821}, {1775, 1817}, {1770, 1831}, {1818, 1883}, {1777, 1855}, {1766, 1817}, {1870, 1924}}

llpd = MapIndexed[Thread@{#, First@#2} &, dates];

legends = MapIndexed[SwatchLegend[{ColorData[{"Rainbow", {1, 7}}][## & @@ #2]}, {#},
                     LegendMarkerSize -> {{10, 10}}] &, names];

ListLinePlot[llpd, Joined -> True, ColorFunction -> "Rainbow",
  Frame -> True, 
  FrameTicks -> {{None,Thread[{Range[7], legends}]}, {Range[1750, 1930,20], Automatic}},
  GridLines -> {Range[1750, 1920, 10], None},
  AxesOrigin -> {1750, 0}, PlotRange -> {{1750, 1930}, {0, 8}},
  PlotStyle -> Directive[Thickness[0.05], CapForm["Butt"]], ImageSize -> 600]

enter image description here

Label the bars with names:

ListPlot[llpd, Joined -> True, ColorFunction -> "Rainbow",
  Frame -> True,
  FrameTicks -> {{None, None}, {Range[1750, 1930,20], Automatic}},
  GridLines -> {Range[1750, 1920, 10], None},
  Epilog -> (Text[Style[#2, 12, Bold], Mean@#1] & @@@ Transpose[{llpd, names}]),
  AxesOrigin -> {1750, 0}, PlotRange -> {{1750, 1930}, {0, 8}},
  PlotStyle -> Directive[Thickness[0.05], CapForm["Butt"]], ImageSize -> 600]

enter image description here

Use the option PlotLabels

In versions 10.4+, we can also use the option PlotLabels:

ListLinePlot[llpd, Joined -> True, 
 PlotLabels -> legends, 
 ColorFunction -> "Rainbow", Frame -> True, 
 GridLines -> {Range[1750, 1920, 10], None}, AxesOrigin -> {1750, 0}, 
 PlotRange -> {{1750, 1930}, {0, 8}}, 
 PlotStyle -> Directive[Thickness[0.05], CapForm["Butt"]], ImageSize -> 600]

To remove the callout curves, use

% /. _BSplineCurve -> {}

Borrowing from kguler the legends

    legends = 
 MapIndexed[
  SwatchLegend[{ColorData[{"Rainbow", {1, 7}}][## & @@ #2]}, {#}, 
    LegendMarkerSize -> {{10, 10}}] &, names]; 
p1 = 
 ListLinePlot[par, ColorFunction -> "Rainbow", 
  Ticks -> {Range[1750, 1980, 10], Automatic}, 
  PlotRangePadding -> {{5, 50}, {0, 1}}, 
  GridLines -> {Range[1750, 1920, 10], None}, 
  PlotStyle -> Thickness[0.02], ImageSize -> 600];
 p2 = 
 Graphics[Inset[
     legends[[#]], {1940 + StringLength[names[[#]]], #}] & /@ 
   Range[7]]; Show[p1, p2]
