1. All measures are in pixels

ImageSize = width:160 height:550 PlotArea = left:50 right:0 bottom:10 top:10 AlignBars = justify

DateFormat = yyyy Period = from:1919 till:1991 TimeAxis = orientation:vertical ScaleMajor = unit:year increment:5 start:1920

1. there is no automatic collision detection,
2. so shift texts up or down manually to avoid overlap

Define $dx = 25 # shift text to right side of bar

PlotData=

 bar:Leaders color:red width:25 mark:(line,white) align:left fontsize:S
