On Mathematica bar charts, you can add tooltips showing the values for each bar thus:
BarChart[data] /.
Rectangle[a_, {b_, c_}] :> Tooltip[Rectangle[a, {b, c}], c]... until the collector arrives ...
This "blog" is really just a scratchpad of mine. There is not much of general interest here. Most of the content is scribbled down "live" as I discover things I want to remember. I rarely go back to correct mistakes in older entries. You have been warned :)
