Common Chart Types Applications In Tableau

Dual-axis charts: A dual-axis chart is used when the ranges of the quantitative variables differ significantly. In such a bar chart, there are two y-axes, one on each side representing a quantitative variable. The categorical variable is represented on the x-axis.

Heat Maps: Used to plot the variation of one measure against one or two dimensions. The heat maps highlight high and low values out of all the values.   

Top N parameters and calculated fields: The top N parameters are a modification to the original parameters. It is generally used to analyze the topmost data values out of a large data set. Calculated fields are used to perform complex calculations on the existing attributes to achieve the required analysis.

Filter actions: Filter actions allow higher levels of visualization interactivity. By selecting a specific category, the dashboard can be filtered to highlight that category. These can be triggered on selection or hovering, depending on your preference.

Dashboards: A dashboard is a collection of multiple sheets arranged in a visually appealing manner. They allow you to visualize and analyze different kinds of data simultaneously.

Storytelling: You learned the following points about stories in Tableau:

• A story is a sequence of visualizations that work together to convey information. You can create stories to present a data narrative, provide context, demonstrate how decisions relate to outcomes, or simply make a compelling case.

• Stories contain slides where you can add various sheets and dashboards. You can also annotate certain points or areas that you want to highlight.

• Since a story is a sheet, the methods that you use to create, name, and manage worksheets and dashboards can be applied to stories as well.

In the next session, you will practice some questions.
