Value on top of grouped bar graph?

Assume we had

y=[2 3 4; 1 5 2; 6 2 5] 
bar(y)

Would there be anyway to get the value of the bar graphs on top of the bars?

What version of Matlab are you using?

Hi Ibro,

You can calculate the bar offsets within each group and use the text function to plot the y values on top of each bar.

y = [2 3 4 ; 1 5 2; 6 2 5];
b = bar(y);
width = b.BarWidth;
for i=1:length(y(:, 1))
    row = y(i, :);
    % 0.5 is approximate net width of white spacings per group
    offset = ((width + 0.5) / length(row)) / 2;
    x = linspace(i-offset, i+offset, length(row));
    text(x,row,num2str(row'),'vert','bottom','horiz','center');
end
