MATLAB: How can i put an edge color on a specific bar

bar

y = [2 4 3];
b = bar(y);
b(1,2).LineWidth = 2;
b(1,2).EdgeColor = 'red';

I want to change only the second bar edge to red. How can i do it?

y = [2 4 3];
b = bar(y);
hold on
h=bar(y(1:2))
set(h,'EdgeColor', 'red','LineWidth', 2);

MATLAB: How to display a value on bar

Try this (if you have R2014b or later):

y1 = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
hBar = bar(y1,1);                                                   % Return ‘bar’ Handle
for k1 = 1:size(y1,2)
    ctr(k1,:) = bsxfun(@plus, hBar(1).XData, hBar(k1).XOffset');    % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
    ydt(k1,:) = hBar(k1).YData;                                     % Individual Bar Heights
    text(ctr(k1,:), ydt(k1,:), sprintfc('%.1f', ydt(k1,:)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom', 'FontSize',8, 'Color','b')
end

the sprintfc function is undocumented. It is essentially the same as sprintf, and augmented to produce a cell array of outputs. This makes it very efficient in situations such as this, where the result is a cell array.

MATLAB: Changing bar graph bar colors

By default, all the bars in a bar graph are part of the same patch object, and therefore are the same color. To get different colors, you need to plot each bar as its own object.

x = 1:4;
y = rand(1,4);
h = bar(x, diag(y), length(y));
set(h, {'facecolor'}, {'k','b','g','r'}');

h = bar(x, diag(y), 'stacked');
set(h, {'facecolor'}, {'k','b','g','r'}');
