Hello everyone, I just wanted to know, if there is a way to plot Histogram and probability density function in one graph, as I wanted to check if the pdf agrees with my histogram. Thank you in advance :)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%Tree Diameter %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Tree Diameter histogram
L = 0:0.1:0.6;
load Tree_Diameter.mat
figure;
histc(Tree_Diameter,L)
bar(L,histc(Tree_Diameter,L),'histc')
xlabel('Diameter (m)'); ylabel('Frequency');
title('Tree Diameter Histogram')
% Tree Diameter Probability (lognormal)
pd = fitdist(Tree_Diameter,'lognormal')
y = pdf(pd,L)*0.1;
figure;
plot(L,y,'LineWidth',1)
xlabel('Tree Diameter (m)'); ylabel('Probability');
title('Tree Diameter')
% Tree Diameter PDF (lognormal)
mu = -1.61825;
sigma = 0.457151;
x = (0) : (sigma / 100) : (mu + 5 * sigma);
pdflognpdf = lognpdf(x, mu, sigma)/10; %/10
figure;
plot(x, pdflognpdf,'g');
xlabel('Diameter (m)'); ylabel('Pdf');
title('PDF for Tree Diameter');

If you have the Statistics and Machine Learning Toolbox, use the histfit function.
