是否有可能使用直方圖（）繪製的，而不是HIST（）

Question

多列直方圖側由端在Matlab使用hist()功能，可以繪製該：

Matlab的建議使用histogram()代替hist()。

在使用histogram()同積繪製多個直方圖導致這樣的：

的列彼此重疊，並且不併排側。

是否可以在同一個圖中使用histogram()函數繪製直方圖與並列？如果是的話，我該怎麼做？

代碼片段：

a = randn(100, 2); 

edges = -3:3; 
xbins = edges(1:end-1)+0.5; 

figure(1) 
hist(a, xbins) 

figure(2), hold on 
histogram(a(:, 1), edges) 
histogram(a(:, 2), edges) 

Answer 1

這個怎麼樣？

histograms in two separate subplots

x1 = randn(100,1); 
x2 = randn(100,1); 

figure_rows = 1; 
figure_cols = 2; 

figure 
subplot(figure_rows, figure_cols, 1); 
histogram(x1); 
title('Hist One') 

subplot(figure_rows, figure_cols, 2); 
histogram(x2); 
title('Hist Two')  

Answer 2

這個怎麼樣？

Click here for a picture of the resulting plot

data1 = randn(1000,1); 
data2 = randn(1000,1); 
data2 = data2 - 1.5*ones(size(data2)); 

lowest_boundary = min(min(data1), min(data2)); 
highest_boundary = max(max(data1), max(data2)); 
nbins = 10; 

boundaries = linspace(lowest_boundary, highest_boundary, nbins + 1); 

bin_assighnments1 = discretize(data1, boundaries); 
bin_assighnments2 = discretize(data2, boundaries); 

bin_counts1 = zeros(numel(boundaries) - 1, 1); 
bin_counts2 = zeros(numel(boundaries) - 1, 1); 

for m = 1:numel(bin_assighnments1) 
    n = bin_assighnments1(m); 
    bin_counts1(n) = 1 + bin_counts1(n); 

    n = bin_assighnments2(m); 
    bin_counts2(n) = 1 + bin_counts2(n); 
end 

merged_bin_counts = cat(2, bin_counts1, bin_counts2); 

x = zeros(1, nbins); 

for m = 1:nbins 
    x(m) = (boundaries(m) + boundaries(m+1))/2; 
end 

bar(x, merged_bin_counts);
