errorbar with mean and standard deviation
显示 更早的评论
Hello, everyone. I have two input data (mean and standard deviation). I would like to create a graph similar to this one:
I have not found a suitable code. I had thought of an "errorbar". Does anyone know how to draw this graph?

% First, I create a random matrix x, and calculate
% the mean (x_mu) and standard deviation (x_std) of
% each column
% *You have this already*
N = 10;
x = randn(100,N);
x_mu = mean(x,1);
x_std = std(x,0,1);
% Now make the plot:
figure();
% mean +/- std:
x_max = x_mu+x_std;
x_min = x_mu-x_std;
% XData and YData of the error bar lines:
xd = (1:N)+([-0.1; 0.1; 0; 0; -0.1; 0.1; NaN]);
yd = [x_max([1 1 1],:); x_min([1 1 1],:); NaN(1,N)];
% create the error bar lines:
line(xd(:),yd(:),'Color','k');
% create a line for marking the mean of each column of x:
line(1:N,x_mu, ...
'Marker','s', ...
'MarkerSize',12, ...
'LineStyle','none', ...
'Color','k', ...
'MarkerFaceColor','w');
% set the grid and xlim:
grid on
xlim([0 N+1]);

OK, that's what I wanted!
But in my case it appears as follows (as if the background inside the square is transparent and not white):
p.s. Is it possible to enlarge the square?

I edited the answer shortly after posting it to change the square background to white (and edited again now to increase the size of the square).
Please check the latest version of the answer.
