MATLAB: How to plot histogram from two vectors

histogram

Can someone help me how can I plot a histogram when I have two vectors where one vector is the x values say x=[1 2 3 4 5] and y is the count of each x y=[5 3 2 6 1]

You want to use bar()

    x = 1:5;
    y = [5 3 2 6 1];
    bar(x,y)

 y=[3,5]; x=1:6; hist(y+0.5,x+0.5)

What you've put doesn't really make sense. See if this is what you want. It computes the histograms of x and y and then plots them.

clc; % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;  % Erase all existing variables.
workspace;  % Make sure the workspace panel is showing.
fontSize = 15;
x=rand(10,1); 
y=rand(10,1);
% Plot the original x data.
subplot(2, 2, 1);
bar(x);
xlabel('Index of X', 'fontSize', fontSize);
ylabel('Value of X', 'fontSize', fontSize);
title('X as a function of Index', 'fontSize', fontSize);
% Plot the original y data.
subplot(2, 2, 2);
bar(y);
xlabel('Index of Y', 'fontSize', fontSize);
ylabel('Value of Y', 'fontSize', fontSize);
title('Y as a function of Index', 'fontSize', fontSize);
% Get the histograms.
[xCounts xValues] = hist(x)
[yCounts yValues] = hist(y)
% Plot X histogram.
subplot(2, 2, 3);
bar(xValues, xCounts);
xlabel('Value of X', 'fontSize', fontSize);
ylabel('Frequency of Occurrence for X', 'fontSize', fontSize);
grid on;
title('Histogram of X', 'fontSize', fontSize);
subplot(2, 2, 4);
bar(yValues, yCounts);
xlabel('Value of Y', 'fontSize', fontSize);
ylabel('Frequency of Occurrence forY', 'fontSize', fontSize);
grid on;
title('Histogram of Y', 'fontSize', fontSize);
% Enlarge figure to full screen.
set(gcf, 'Position', get(0,'Screensize'));
