Hi I have some code as below to draw a bar graph, at the moment I can set the border of each bar using "ChartBaseStyle" option, which sets the border around each bar to "Black". I would like to set different color border for each bar, below code generates 3 sets of bars colored "light gray" and "dark gray". I want to have no border for light gray bars and a black color border for dark gray bars is this achievable using "ChartelementFunction" option, if so can anyone please help me on this. Thanks Nalina
levels = GrayLevel /@ {0.9, 0.5};
data1 = {{0.25, 0.4}, {0.172, 0.25}, {0.101, 0.26}};
BarChart[data1, BarSpacing -> {0.15, 1}, PlotTheme -> "Business",
ChartLegends -> {Text[Style["BXE", 12]], Text[Style["TQ", 12]]},
ChartStyle -> levels, LabelingFunction -> Above,
ChartLabels -> {{"Large", "Small", "Overall"}, None},
BaseStyle -> Directive[FontSize -> 11],
PlotLabel -> Style["Volume", FontSize -> 15],
ChartBaseStyle ->
Directive[EdgeForm[{Thin, RBAGreys[10], Opacity[1]}]]]
