在 MATLAB Online 中打开

Two histograms:

x = -2.9:0.1:2.9;
y = randn(10000,1);
hist(y,x) 
h = findobj(gca,'Type','patch');
set(h,'FaceColor','r','EdgeColor','w')
z = randn(size(y))/3;
hold on  % make sure next one shows up.
hist(z,x)

Does the second hist cover up the first? Try hist(True_probability,x) first, then doing hist(proestimated,x).
