Chapter 12, Problem 12.1P

To determine

To create:

A file that has two lines with n numbers in each and use subplot to show the barh and stacked bar charts side by side.

Answer to Problem 12.1P

Solution:

The script file is,

l = load('ponits.dat');

%load the points data file.

subplot(2, 1, 1)

%by using subplot show the bar graph and stacked bar graph side by side.

barh(l);

%plot the bar graph.

xlabel('Values');

%label the x axis as values.

ylabel('Groups');

%label the y axis as values.

subplot(2, 1, 2)

bar(l,'stacked');

%plot the stacked bar.

xlabel('Groups');

%label the x axis as groups.

ylabel('Values');

%label the y axis as values.

Explanation of Solution

Consider, the vectors are,

$\text{x}=\left[240536292021\right]$

$\text{y}=37813141813$

MATLAB Code:

l = load('ponits.dat');

%load the points data file.

subplot(2, 1, 1)

%by using subplot show the bar graph and stacked bar graph side by side.

barh(l);

%plot the bar graph.

xlabel('Values');

%label the x axis as values.

ylabel('Groups');

%label the y axis as values.

subplot(2, 1, 2)

bar(l,'stacked');

%plot the stacked bar.

xlabel('Groups');

%label the x axis as groups.

ylabel('Values');

%label the y axis as values.

Save the MATLAB files with name, chapter12_54793_12_1P.m in the current folder. Execute the file by typing the name at the command window to generate output.

Result:

The plot is,

Therefore, the result is stated above.
