Phase 1 - Tableau Dashboards - Lab

Tableau Dashboards - Cumulative Lab

Introduction

In previous lessons we have utilized the provided Superstore Sales dataset to learn about the Tableau environment interface, including the Start page, Data Source page, and Workspace/Worksheets. Then, we explored the useful visualizations that can be created in Tableau Public. Finally, we discussed how we can combine the vizualizations in our workbooks to create dashboards to communicate our insights. Now it's your turn to apply your skills in Tableau.

In this exercise, you will use knowledge of the Tableau interface and data visualizations to create the Super Store Sales dashboard. Refer to previous lessons and labs if needed!

To create the dashboard, follow the instructions below. When you are finished, save and publish your completed dashboard to your Tableau Public account. Then, add the link to your dashboard in this assignment in canvas and click submit. You've just created your first interactive dashboard with Tableau Public.

The final product should look like this:

Instructions

Part A - Connect to THE Data Source and Create a New Workbook

  1. Launch Tableau Public and from the Start page, use the Connect pane to open the SuperStore Sales dataset. It can be found in this repo or it can also be downloaded directly from Tableau Public.
  2. On the Data Source page, populate the page with the Orders table and the People table. Remember that Tableau will automatically form a relationship if/when possible.

Note: This data file is updated periodically by Tableau, newer versions might display different names/infomation then shown below.

Part B - Create a Bar Chart

For Part B, use lessons "Tableau Visualizations: Visualization Basics" and "Tableau Visualizations: Visualization Basics Lab" as a reference.

  1. Create a new worksheet - title it "Profits by Sub-Category"
  2. Drag the Profits pill to the Columns shelf from the Data Pane.
  3. Drag the Sub-Category pill to the Rows shelf from the Data Pane.
  4. Edit the title to be centered and have font size 16. Format the title background/shading to be light gray. Format Title > Shading dropdown.
  5. Order the bars in descending order.
  6. Next, drag the Profits pill from the Data pane to the Marks card, and use the Marks card to change the color of the bars to "Orange-Blue Diverging".
  7. Next use the Marks card to add labels that indicate the sum of the profits for each of the bars by dragging another Profits pill from the Data pane and using the label mark. Format the labels using "Currency (Custom)" under the Numbers formatting option. Display the amount in thousands with the dollar sign symbol. Bonus: Change the axis label to include "Thousands"
  8. Fit the visualization to "Entire View".

Part C - Create a Regional Map

For Part C, use lessons "Tableau Visualizations: Visualization Basics" and "Tableau Visualizations: Visualization Basics Lab" as a reference.

  1. Create a new worksheet - title it "Sales By Regional Manager". Change the font size to 16, center the title, and change the background to light gray again.
  2. Drag the Longitude and Latitude to the Columns shelf and the Rows shelf respectively.
  3. Add Sales to the Marks card, and select the Size attribute. Then, add Postal Code to the Marks card and select the Detail attribute. This will populate the map with sales by postal code. Using the Show Me dropdown, select symbol map if Tableau did not default to the map view.
  4. Rename Person pill to be Regional Manager by right clicking > Rename.
  5. Drag the "new" Regional Manager pill to the Marks card and select the Color attribute.
  6. Also drag the Region pill into the Marks card without selecting a specfic mark. Then left click and change it to color. This should get you both the name and the region as one color label.
  7. Then, click the Color icon and select Edit Color. Using the Color Blind pallete, assign the following colors to each Regional Manager, Region:

  1. Next, drag Profit to the Marks card and add the Detail attribute. This will allow users to view the profits in conjunction with sales (because high sales does not always mean high profits).
  2. Then, drag Regional Manager to the Filter shelf. Click the dropdown arrow on the new filter and select Apply to Worksheets > All Using This Data Source. This will allow the filter to work across the dashboard.

Part D - Create a Time Series Line Graph

For Part D, use lessons "Tableau Visualizations: Visualization Basics" and "Tableau Visualizations: Visualization Basics Lab" as a reference.

  1. Create a new worksheet - title it "Quarterly Sales by Region". Change the title to size 16, center it, and color the background light gray as before.
  2. Drag the Sales and Order Date pills from the Data pane to the Row shelf and the Column shelf respectively. You will notice that Sales becomes SUM(Sales) and that Order Date becomes YEAR(Order Date). On the YEAR(Order Date) pill, click the arrow directly to the right of the text on the YEAR(Order Date) pill. This will reveal a drop down menu. Select Quarter from the dropdown, which will change YEAR(Order Date) to Quarter(Order Date).
  3. Add Regional Manager to the Marks card, and select the Color attribute. In the same manner as the previous figure, also add Region to the Marks card without choosing a mark and then change it to color.
  4. Confirm that your colors match. Tableau should default to the existing colors you used previously but you should double check to confirm they match!
  5. Drag the Sales pill to the Marks card and choose Label, format the amounts appropriately.
  6. Finally, drag the Profit pill to the Marks card and select Tooltip.
