MATPLOTLIB

This problem will test your ability to use the Python module matplotlib. For this problem, review the part of Section $7\mathrm{.}11$ labeled Plotting a Bar Graph. Review Programs $7-25$ through $7-27$ for examples of using matplotlib to create a bar graph. The example code provided with the lecture videos will be very useful as well.

Create a file named Lab$06$P$4.$py$.$ Write a program that helps a user generate a line graph graphic:

a$)$ As discussed in the book, you will need to use the Python utility pip to install matplotlib. Follow the instructions in the book for details.

b$)$ After your program comment header, add the appropriate line for importing the module matplotlib that makes it convenient to work with the pyplot portion of the module:

import matplotlib.pyplot as plt

c$)$ Your program should ask the user to enter a title for a bar graph.

d$)$ The program should ask the user for labels for the x$-$axis and y$-$axis.

e$)$ The program should ask the user for the number of data points.

f$)$ Then your program should ask the user for the data point labels and values using a for loop. The labels will be used to label the bar locations on the x$-$axis. The values will be used to plot the bar heights to the y$-$axis.

g$)$ After collecting the user's input into a list of labels and a list of values, use the appropriate pyplot functions to do the following:

a$.$ Create the bar graph.

b$.$ Add a title for the chart.

c$.$ Add labels for the x$-$axis and y$-$axis.

d$.$ Display the bar graph.

h$)$ The program terminates after the user closes the window displaying the bar graph.

Sample output:

Enter the bar graph title: Daily Temps

Enter the label for the x$-$axis: Day of Week

Enter the label for the y$-$axis: Temperature

Enter the number of data points: $7$

Enter the name for tick $1$: Mon

Enter the value for tick $1$: $66$

Enter the name for tick $2$: Tue

Enter the value for tick $2$: $72\mathrm{.}3$

Enter the name for tick $3$: Wed

Enter the value for tick $3$: $76$

Enter the name for tick $4$: Thu

Enter the value for tick $4$: $74\mathrm{.}8$

Enter the name for tick $5$: Fri

Enter the value for tick $5$: $82$

Enter the name for tick $6$: Sat

Enter the value for tick $6$: $79\mathrm{.}6$

Enter the name for tick $7$: Sun

Enter the value for tick $7$: $75\mathrm{.}1$

Run this program. Enter any test data you would like. When your program displays the bar graph, use the save button to save the graph to a file named Lab$06$P$4-$output.png$.$
