sd1 = 1081;

mu1 = 1800;

data1 = mu1+ sd1.*randn(5000,1);

sd2 = 1356;

mu2 = 2551;

data2 = mu2+ sd2.*randn(5000,1);

sd3 = 1262;

mu3 = 2331;

data3 = mu3+ sd3.*randn(5000,1);

%bin specs.

nbins = 100;

bound = 10000;

bins = linspace(-bound,bound,nbins);

fig = figure;

% first histogram

y1 = hist(data1,bins);

% second histogram

y2 = hist(data2,bins);

% Third histogram

y3 =hist(data3,bins);

% overlay histograms

bar(y1.');

hold on;

bar(y2.','r');

hold on;

bar(y3.','y');

legend({'Damage Scenario(i)',' Damage Scenario(ii)',' Damage Scenario(iii)'})

% relabel x-axis range/ticks

xd = findobj('property','XData');

for i=1:3

dat = get(xd(i),'XData');

dat = 2*dat/nbins - bound;

set(xd(i),'XData',data);

h=findobj(gca,'Type','patch');

set(h,'FaceColor','white');

end

histfit works. For example

sd1 = 1081;
mu1 = 1800;
data1 = mu1+ sd1.*randn(5000,1);
sd2 = 1356;
mu2 = 2551;
data2 = mu2+ sd2.*randn(5000,1);
sd3 = 1262;
mu3 = 2331;
data3 = mu3+ sd3.*randn(5000,1);
%bin specs.
nbins = 100;
bound = 10000;
bins = linspace(-bound,bound,nbins);
fig = figure;
ax = axes();
hold(ax);
histfit(data1,nbins);
histfit(data2,nbins);
histfit(data3,nbins);
