Tableau Desktop: A Comprehensive Guide

What is Tableau Desktop?

Tableau Desktop is a powerful data visualization and analytics tool that allows you to convert data into interactive and informative visualizations. It’s like a digital canvas where you can create stunning charts, graphs, and dashboards from your data, making it easier to understand and communicate your insights.

Tableau Desktop UI

1. Toolbar: The Toolbar in Tableau Desktop provides access to various tools and functions that allow you to perform tasks like connecting to data sources, creating visualizations, formatting, and more. It includes buttons for actions such as saving, undoing, redoing, and publishing to Tableau Server or Tableau Online.
2. Data Pane: The Data Pane is a critical component that displays all the data sources and fields available for your analysis. It allows you to drag and drop dimensions and measures onto the Rows and Columns shelves to build visualizations. You can also filter and sort data from the Data Pane.
3. Workspace: The workspace in Tableau Desktop refers to the entire application window where you work on your data visualizations. It includes the canvas (where you design visualizations), the Data Pane, the central worksheet area, and various shelves and tabs.
4. Column and Row Shelves: In Tableau Desktop, the Column and Row Shelves are essential components for building visualizations. By dragging and dropping dimensions and measures onto these shelves, you determine the structure and layout of your chart or table. These shelves define what will be displayed on the X and Y axes and rows and columns of your visualization.
5. Canvas: The Canvas is the central area in Tableau Desktop where you create and design your visualizations. It’s where you drag and drop fields to build charts, graphs, maps, and tables. The Canvas is where you interact with your data, arrange marks (data points), and define the appearance of your visualizations.

Once we connect to a data source in tableau , the columns get converted divided into dimensions and measures.

Dimensions and Measures

Dimensions is a field that is an independent variable.

A measure is a field that is dependent variable and its value is a function of one or more dimensions.
