This tutorial demonstrates how to create bar, line, and pie charts using Tableau. It explains the use cases and functionalities of each chart type, including how to represent data based on categories, trends, and percentage distributions. The tutorial covers the functionalities of each chart and provides examples of how to generate different visualizations based on available data and chart specifications.
Bar Chart Creation
• 00:00:38 A bar chart displays data based on categories, such as segments or regions, with values represented by the length of the bars. Users can choose between horizontal or vertical bars, sort data in ascending or descending order, and customize the bars with different colors or stacks for better visualization of different dimensions within the data. For example, a bar chart might show the total sales for different product categories within a specific region.
Line Chart Creation
• 00:03:18 A line chart is used to display data over a period of time, identifying trends and patterns. It is often used with date fields, automatically plotting data points over time. It's helpful to visualize how sales or metrics have evolved, allowing for examination of increases or decreases. Line charts can be modified to create area charts and customize line types and patterns.
Pie Chart Creation
• 00:05:40 Pie charts are used to visualize the percentage distribution of categories or segments within a dataset. They show the proportions of each category using different slices of a circle. Users can easily determine which categories are larger or smaller and compare the percentage contribution of each category to the whole dataset. By choosing ‘Percent of Total’ within quick table calculations, users can visualize the percentage contribution for each category within the whole dataset.
