populations = RandomReal[{15, 25}, 30]; 

mbar[m_] :=
 BarChart[populations, Axes -> None, 
  ChartStyle -> Table[If[i == m, Black, White], {i, 30}], 
  BarSpacing -> Large] 

mbar[19]

I must be missing something trivial but I don't seem to be able to
find a way to highlight a single value from a list in a BarChart.

mbar = BarChart[{populations, populations[[19]]}, Axes -> None,
ChartStyle -> {White, Black}, BarSpacing -> Large];

The above generates a bar chart of the population series with
alternate black/white colour.

mbar = BarChart[{populations, Style[populations[[19]], Red]},  Axes ->
None, ChartStyle -> White, BarSpacing -> Large]

This produces only white bars.

Feedback welcome.

Dario
