The Tableau Interface

When you open Tableau Desktop, several important areas appear.

Rows

Controls what appears along the vertical axis of the visualization.

Columns

Controls what appears along the horizontal axis.

Marks Card

One of the most important areas in Tableau.

You can control:

• Color

• Size

• Label

• Detail

• Tooltip

• Shape

For example, you can put:

• Region → Color

• and Tableau can automatically assign different colors to regions.

Show Me

Show Me provides recommended visualization types based on the fields you select.

It can help beginners understand which visualizations can be created from particular combinations of data.

Dimensions vs Measures

This is one of the most important Tableau concepts.

Dimensions

Dimensions generally describe or categorize data.

Examples:

• Customer

• Product

• Region

• Country

• Department

• Category

They are commonly used to answer: "By what?"

Example: Sales by Region — Here, Region is the dimension.

Measures

Measures are generally numeric values that can be aggregated.

Examples:

• Sales

• Profit

• Quantity

• Revenue

• Discount

They are commonly used to answer: "How much?"

Example: Sales by Region — Here:

• Region → Dimension

• Sales → Measure

Discrete vs Continuous

Another fundamental Tableau concept.

Discrete

Discrete fields create separate, distinct values.

Example: Region — East | West | Central | South — Each value remains separate.

Continuous

Continuous fields represent values along a continuous range.

For example: A date field can create a continuous timeline:

• Jan → Feb → Mar → Apr → May

This distinction affects how Tableau displays fields in your visualization.
