Hi,
I would like to add a LegendLabel to the legend produced by
ChartLegends in a BarChart. As a simple example consider
BarChart[{{1, 3}, {2, 4}}, ChartLabels -> {{"1", "2"}, None},
ChartLegends -> {"a", "b"}]
I would like the label "Letters" to appear on top of the "a" and "b",
with no "marker" on the left.
It can be done in a Plot using the PlotLegends package and the option
LegendLabel; but BarChart does not accept the PlotLegend option. I
tried to do it with ShowLegend, but could not get the colors and the
"markers" for the legend right. Any help would be appreciated.
TIA, Julian.
