Independent – loosely coupled with one another § Negotiable – Stories are what and why , not how ( 99% ). § Valuable – for the customer! § Estimatable – Effort/Cost of design, build, and test. § Small (sized appropriately) § Testable – pass or fail
the system Heading: name for a requirement (service, behavior, or reaction) (a sentence with subject and verb and small context as you consider necessary for a header) Paragraphs: the explanation of the requirement (do not mix ideas) (focus in the goal of the section) You can list here the activities, algorithm, details, etc. (using bullets is a good idea) 1 2 3
with a menu bar (Use a JMenu) § Two items: File and About § About is Easy, will open a dialog box with your team information. § File menu is the important one Jmenu Tutorial https://docs.oracle.com/javase/tutorial/uiswing/components/menu.html
the user for a File path (Use a JFileChooser) • The file will be a CSV (Comma Separated Values) file. • Read the file and load the data into a data structure (your choice) JFileChooser Tutorial: https://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html How to Read CSV File in Java https://www.tutorialspoint.com/how-to-read-the-data-from-a-csv-file-in-java
the data is loaded, visualize it on the screen using a Jtable • Add your JTable in a JScrollPane, you will need scrollbars, both horizontal and vertical Jtable Tutorial https://www.javatpoint.com/java-jtable Dinamically Updating a JTable https://stackoverflow.com/questions/24918884/dynamically-updating-jtable
user for a File path (Use a JFileChooser) • The file is another CSV (Comma Separated Values) file. • Ask for a date Use a Date Picker. Get One or create one • Read the file and load the data into a data structure (one more time, your choice) • Remember the selected date
can appear in more than one row. For instance, a user is connected 20 minutes, go and then connect another 20 minutes. It will appear as jdoe 20 jdoe 20 Merge them in one. And add the minutes. For instance: jdoe 40 75 time ASURITE javiergs • The file does not have headers (orange line). Added only as a reference. • 2 fields per row: • ASURITE (your username in the email) • An integer number that represent how many minutes you where connected in a meeting
the asurite field as a reference, mix the roster data and the attendance data • Visualize the attendance data adding a column to the JTable. The header for the column is the date that the user provided • Any attendee that is not in the roster is ignored. But report it to the user. Use an option of JDialog
Chart using the attendance data per student. Specifically, a Scatter Plot where • Y-Axis is how many students (from 0 to total row in the table) • X-axis is % of attendance (0%, 10% .. 90%, 100%). 100% is 75 minutes or more. • And each attendance column represent a population.
a new JPanel, replace the JTable, Use a tab (JTabbedPane) or a dialog box • Use the JFreeChart library. Mandatory. Tutorial: https://www.javatpoint.com/jfreechart-scatter-chart

Should have a GUI with a menu bar consisting of items ‘about’ and ‘files’ where the file item is a dropdown of ‘load a roster’, ‘add attendance’, ‘save’, and ‘plot data’ sub-menu items. § When clicking on the ‘about’ item in the menu bar, the system should open a dialog box with information about all team members. § When clicking on the ‘Load a Roster’ sub-menu item, the system should show a GUI to take a CSV file as user input and read the file and store the data. § Show the roster data on GUI in table format. § When clicking on the ‘Add Attendance’ sub-menu item, ask the user to load an attendance CSV file using GUI and store the data.
Show the attendance data on GUI in table format with merging attendance of duplicate ASURITE. § Should take user input of date and merge the attendance to the roster for that date and display the merged data on GUI in the form of a table. § When the roster and attendee’s merged data is displayed, show a dialog box with a message telling how many students from the roster attended & attendance details of students who attended but weren't on the roster. § When a user clicks on save in the sub-menu item, the system should generate a CSV file of the merged roster and attendance data and save the file. § When a user clicks on the plot data sub-menu item, the system should show a scatter graph of attendance percentage on the number of students versus the date on GUI.
