Bar(matrix) with errorbars on the same figure
显示 更早的评论
Hi
I'm trying to plot bar with errorbars on the same figure. I tryed but it doesn't seem to work. Code: a=<4x4 double> = [0,1,0,0; 4,3,2,1; 2,2,1,3; 1,0,0,0] b=<4x4 double> = [0,1,0,0; 1,2,1,1; 1,1,1,2; 1,0,0,0] bar(a); hold on;errorbar(a,b,'.'); the answer is
How to put errorbar on each bar?

My pleasure!
This works for me, and seems to produce the correct plot.
The Code:
a=[0,1,0,0;
4,3,2,1;
2,2,1,3;
1,0,0,0];
b=[0,1,0,0;
1,2,1,1;
1,1,1,2;
1,0,0,0];
ctrs = 1:4;
data = a;
figure(1)
hBar = bar(ctrs, data);
for k1 = 1:size(a,1)
ctr(k1,:) = bsxfun(@plus, hBar(1).XData, [hBar(k1).XOffset]');
ydt(k1,:) = hBar(k1).YData;
end
hold on
errorbar(ctr, ydt, b, '.r')
hold off

I assumed you were using R2014b or later. I can no longer run this code (archived from a 2014 Answer), so I will let you adapt it. The loop is different for R2014a and earlier:
load('Mean.mat') % Mean contains all mean values and consists of 5 rows
load('Stddeviation.mat')
x = [time]; % define x-axis
y = [IC1,IC2,IC3,IC4]; % define y-axis
e = [sd1,sd2,sd3,sd4,sd5,sd6]'; % define standard deviation
figure
hBars = bar(y,1.0,'grouped');
set(gca,'XTickLabel',{'Baseline','0,1','0.2','0.3','0.4','0.5'})
% set ticks and tick labels
xlabel('Time')
ylabel('Impulse')
hold on
for k1 = 1:4
hb = get(get(hBars(k1),'Children'), 'XData');
midbar = mean(hb);
errorbar(midbar, y(:,k1), e(:,k1), '.') % plotting errors
end
title('Impulse');
legend('a','b','c','d','Location','SouthEastOutside')
% put in lower right
box off
hold off
