Step-by-Step Tableau Tutorial for Beginners

Tableau is the leading tool for visual data analysis! This tutorial walks you through how to set up Tableau Desktop and build your first interactive visualization—a must-have skill for any data professional.

Step 1: Installation and Setup (Tableau Desktop)

Tableau has a number of products, but its core tool for creating visualizations is Tableau Desktop.

1.1: System Requirements Check

First, make sure that your computer meets the minimum requirements for running VideoScribe: Windows 7 or newer, macOS 10.13 or newer, 64-bit processor, minimum 2 GB RAM.

1.2: Download Tableau Desktop

• Go to the official website of Tableau and click on the Products link.
• Download Tableau Desktop – Free Trial (there are often free annual licenses available for Students and Teachers).
• Launch the executable file, downloaded (\.exe or \.dmg)
• Follow the installation wizard, accept the license agreement, and select the default installation path.
• Open Tableau Desktop. You will be prompted to register the product or start the free trial.

1.3: Understand the Start Page

When you open Tableau, you first see the Start Page. This page is divided into three main sections:

• Connect: Where you select data source, such as File, Server, and Saved Data Source.
• Open: Lists recently opened workbooks.
• Discover: Links to training resources, blogs and Tableau Public gallery.

Step 2: Connecting to Data

The first step in any analysis is connecting Tableau to your raw data.

2.1: Connect to a File

For this walkthrough, we’ll use a standard Excel file, which is readily available.

1. In the Connect pane, to the left, under the To a File section, click Microsoft Excel.
2. Open a plain, clean Excel file from your computer. An example might be a list of sales transactions, where each transaction lists the Region, Product, Sales Amount, and Date.

Note: Tableau comes with sample datasets; you can also use the Superstore Sample Data provided under Saved Data Sources for practice.

2.2: The Data Source Page

After connecting, Tableau takes you to the Data Source page.

1. Connection Pane (Left): Displays the files and sheets within your connection.
2. CANVAS (Center): This is where you drag the sheet that you want to use-such as “Orders” or “Sales”-onto the canvas.
3. Data Grid (Bottom): This shows a preview of the top few rows of your data.
4. Data Interpreter: If your Excel file contains merged cells, extra headers, or empty rows, use the Data Interpreter, shown at top right, to automatically clean the sheet before loading.
5. Rename/Check Fields: Make sure Tableau accurately detected the field name and data type (for example “Sales” should be a number, “Date” should be a date). To change the data type click the icon above each column header.

Step 3: Understanding the Tableau Workspace

When you have prepared your data, click the Sheet 1 tab at the bottom of the screen, or the Go to Worksheet button in the top menu, to access the main visualization workspace.

3.1: Components of the Workspace

The main workspace is where you spend most of your time:

1. Data Pane (Left): This lists all the fields from your data source and organizes them into two key groups:
   • Dimensions (Categorical Data): These include fields that are qualitative or categorical in nature, like Region, Product Name, and Customer ID. They define how the data is grouped.
   • Measures (Quantitative Data): Fields containing numerical, quantitative values that can be aggregated. Examples include Sales, Profit, and Quantity. These define what is measured.
2. Shelves (Top): This includes the Columns Shelf and Rows Shelf. Dragging fields here will create the structure of your visualization.
3. Marks Card (Center Left): The most powerful element. It controls the visual properties of your marks (data points):
   • Color: Changes the color of the marks.
   • Size: Changes the size of the marks – for instance, larger bubbles for higher sales.
   • Label: Shows the actual value of the data on the mark.
   • Detail: Adds more granularity to the view without changing the aggregation.
4. View (Center): The area where your visualization is built and displayed.
5. Show Me (Top Right): A pane that recommends visualization types based on the fields you have currently selected.

Step 4: Creating Your First Visualization – Line Chart

Let’s create a Time Series Line Chart to see how Sales have changed over time.

4.1: Create the Time Series Axis (Columns)

1. In the Dimensions pane, find the Order Date field.
2. Drag Order Date and drop it onto the Columns Shelf.
   • Tableau will automatically aggregate the date to the Year level and create a header for each year.

4.2: Set up the Sales Value (Rows)

1. Find the Sales field in the Measures pane.
2. Drag Sales and drop it onto the Rows Shelf.
   • Tableau automatically aggregates Sales using the SUM function and draws a single mark – a dot – since there is only one data point for the overall sum of sales per year.

4.3: Drill Down to Detail

To create a line connecting the dots (line chart):

1. Click the + sign on the YEAR(Order Date) pill on the Columns Shelf.
2. This “drills down” and adds Quarter (Order Date) to the view. Tableau redraws the visualization as a line chart, displaying sales broken down by quarter within each year.
3. Click the + sign again to drill down to Month (Order Date) for a more granular view.

4.4: Add Color Encoding

Let’s see the contribution of different product categories to the overall sales trend.

1. Find the Category field (a Dimension).
2. Drag Category and drop onto the Color button on the Marks Card.
3. The single line chart is now split into three separate lines, coloured according to different categories, such as Furniture, Technology, Office Supplies. A Legend will automatically appear.

Step 5: Building a Second Visualization (Map)

Let’s create a geographical map that compares sales across states or regions.

5.1: Create a New Sheet

Click the New Worksheet icon (the grid with a plus sign) at the bottom of the screen next to “Sheet 1”. Name this new sheet “Sales Map”.

5.2: Create the Base Map

1. Find the State or Region field (a Dimension).
2. Double-click the State field.
   • Tableau instantly recognizes this as a geographic field, and puts it onto the Detail shelf while it places the generated Latitude and Longitude fields onto the Rows and Columns shelves, respectively, creating a dot map.

5.3: Encode Sales by Color and Size

1. Find the Sales field (a Measure).
2. Drag Sales and drop onto the Color button on the Marks Card.
   • The colour of the map will now reflect the total value of sales within each state – a “Filled Map” is often more effective, which can be selected via the Show Me pane.
3. Drag Sales and drop it onto the Size button on the Marks Card.
   • The dots will now be larger/darker for states with higher total sales, giving a dual encoding of the map fill intensity.

Step 6: Creating an Interactive Dashboard

A dashboard is a combination of different visualizations on a single canvas to offer an overview of the data.

6.1: Create a New Dashboard

Click the New Dashboard icon at the bottom of the screen – the four-panel grid.

6.2: Add Sheets to the Dashboard

1. The Left Dashboard Pane lists the sheets you created: Sheet 1/Time Series and Sales Map.
2. Drag the Sales Map sheet into the center of the dashboard canvas and drop.
3. Drag the Time Series sheet, and drop it underneath the map. Tableau will automatically arrange them.

6.3: Make the Dashboard Interactive (Filters)

The strength of a dashboard is interactivity. Let’s make the map filter the line chart.

1. On the dashboard, select the Sales Map visualization.
2. Click the small funnel icon (Use as Filter) that appears when you hover over the visualization in the dashboard pane.
3. Test It: Now click on one of the states in the map below. The time series line chart underneath it will immediately refresh, displaying the sales trend for only that clicked state, providing strong regional drill-down analytics.

Step 7: Saving and Sharing Your Work

7.1: Save the Workbook

1. Click File → Save As.
2. Save the file as a Tableau Workbook (.twb) if you want to save only the visualization structure, or a Tableau Packaged Workbook (.twbx) if you want to save the structure and a copy of the underlying data in order to share the file easily with other users who don’t have access to your original data source.

7.2: Sharing Options

• Tableau Public: Free Service for public sharing of visualizations online.
• Tableau Server/Cloud: Enterprise platforms for enabling secure, private sharing within an organization.
• Export: You can export the dashboard as a static image or PDF via File → Print to PDF.

You have connected data, created two basic types of visualizations-a line chart and a map-and combined them into an interactive dashboard. You’ve gone from raw data to data-driven insights, which is the backbone of a successful data analyst’s job.
