The following are some of the types of charts in Tableau:
Bar Chart
Bar Charts are used to compare the data across categories, highlight differences, and show trends and outliers quickly at a glance.
Line Chart
Line charts are used to understand the trends in data, mainly over time. Some examples include stock price changes over ten years and the website page views in the first quarter.
Scatter Plot
Scatter plots are used to understand the relationship between different variables, showing if one variable is a good predictor of another, or how they are dependent on another variable.
Gantt Chart
Gantt charts are used in project management to ensure the projects are delivered on time by showing the various elements of a project like how much time it will take as well as when they will be completed.
Bubble Chart
Bubble charts are used to determine which categories occur most often by looking at the size of the bubble and mainly to understand the relation between three or more measures.
Treemap
Treemap Charts are used to show hierarchical data using size and color.
