タイムラインのレイアウトとラベルの配置

ロマン派の著名人のタイムラインを生成する．

In[1]:=

romanticerapeople = DeleteCases[ EntityValue[ Entity["HistoricalPeriod", "RomanticEra"][ "PeopleInvolved"], {"BirthDate", "DeathDate", "Name", "Image", "Occupation"}], {__, _Missing}];

In[2]:=

lifespan = GroupBy[romanticerapeople, Last -> (Tooltip[ Labeled[Interval@#[[1 ;; 2]], #[[3]], "StartBubble"], Labeled[#[[4]], DateDifference[#[[1]], #[[2]], "Year"]]] &)];

各作曲家を別々の行で表示する．

In[3]:=

TimelinePlot[lifespan[{"composer"}], PlotLayout -> "Stacked", LabelStyle -> 12, ImageSize -> 550, PlotLabel -> "Romantic Era Composers", PlotTheme -> "Grid"]

Out[3]=

行数を最少にする．

In[4]:=

TimelinePlot[lifespan[{"composer"}], PlotLayout -> "Grouped", LabelStyle -> 12, ImageSize -> 550, PlotLabel -> "Romantic Era Composers", PlotTheme -> "Grid"]

Out[4]=

各作曲家が亡くなった年に名前のラベルを置く．

In[5]:=

lifespan = GroupBy[romanticerapeople, Last -> (Tooltip[ Labeled[Interval@#[[1 ;; 2]], #[[3]], "EndBubble"], Labeled[#[[4]], DateDifference[#[[1]], #[[2]], "Year"]]] &)];

In[6]:=

TimelinePlot[lifespan[{"composer"}], LabelStyle -> 12, ImageSize -> 550, PlotLabel -> "Romantic Era Composers", PlotTheme -> "Grid"]

Out[6]=

データ項目が多く，スペースが限られている場合は，それぞれのタイムラインの最後にラベルを置く．

In[7]:=

lifespan = GroupBy[romanticerapeople, Last -> (Tooltip[Labeled[Interval@#[[1 ;; 2]], #[[3]], After], Labeled[#[[4]], DateDifference[#[[1]], #[[2]], "Year"]]] &)];

In[8]:=

TimelinePlot[Values@lifespan, PlotLayout -> "Grouped", LabelStyle -> 14, AspectRatio -> 1/1.2, ImageSize -> 450, PlotLegends -> LineLegend[Flatten@Keys[lifespan], LegendLayout -> "ReversedColumn"], PlotTheme -> "Web"]

Out[8]=

このデータ集合に「Packed」というレイアウトを使う．

In[9]:=

TimelinePlot[Values@lifespan, PlotLayout -> "Packed", LabelStyle -> 14, AspectRatio -> 1/1.2, ImageSize -> 450, PlotLegends -> LineLegend[Flatten@Keys[lifespan], LegendLayout -> "ReversedColumn"], PlotTheme -> "Web"]

Out[9]=
