In the last posts we covered Data Visualization and Tableau — Part 1 and Tableau — Part 2.

In this post we will cover Tableau — Part 3 as follows —

Tableau Basics

Create trend lines and understand the relevant statistical metrics such as p-value and R-squared

Create forecasts, Barcharts, Area Charts, Box and Whisker

Create Histogram, Bullet Chart, Bubbles Chart, Funnel Charts, Advanced Charts

Create Scatterplots , Piecharts, Treemaps

Create Maps — Detailed Maps, Symbol Maps, Density Maps

Create Advanced Maps

Create Interactive Dashboards

Create Storylines

Work with Data Blending in Tableau

Create Table Calculations

Create Dual Axis Charts

Create Calculated Fields

Create Visualizations using Calculated Fields

Tableau String Functions

Tableau Date Functions

Tableau Type Conversion

Tableau Reporting

Implement Aggregation, Granularity, and Level of Detail

Create and use Groups

Create and add Filters and Quick Filters

Create Reference Lines with Parameters

Implement Clustering

Implement Filters, including the context filter

Implement Grouping & Sets

Let’s get started with Tableau — Part 3.

Hierarchies

Tableau Hierarchy provides drill-down action to the Tableau report. Using Tableau Hierarchy we can navigate from a higher level to a nested level or lower level as hierarchies arrange data fields in a level

  • You can create hierarchy, drill up and down and remove hierarchy
  • By creating hierarchies in Tableau, we set our data on different levels of detail and organize it

Data Extracts

Data Extracts creates a subset of data from the data source i.e a local copy of portion of data gets saved in Tableau’s memory and it helps to optimize Tableau’s performance, speed and offers flexibility to handle large sets of data easily.

Advantages of Data Extracts —

Support large data sets

Help improve performance

Provide offline access to your data

Support additional functionality

Manipulate or modify the extract data

Data Blending

Data Blending is used when there is related data in multiple data sources, which you want to analyze together in a single view. Blends query each data source independently, the results are aggregated to the appropriate level, then the results are presented visually together in the view

  • The two sources involved in data blending are referred as primary and secondary data source
  • It is performed on a sheet-by-sheet basis and is established when a field from a second data source is used in the view
  • Tableau uses linking field to know how to combine the data from multiple sources.

Filters and Quick Filters

Filters are used to restrict the data as per the requirements as it allows you to select the individual data points or a group of data points

Basic Filters

Filter Dimensions : applied on the dimension fields.

Filter Measures : applied on the measure fields.

Filter Dates : applied on the date fields.

Quick Filters

Tableau provides filters that are quickly available using the right-click option on the dimension or measure

Context Filters

Improves performance

Creates a (second) dependent numerical

Tableau Custom Views

It’s a saved version of the view with your selections and filters applied. It lets you save your filters, sorts, or selections, without making changes to the underlying view

  • You can also extend the normal data views with some additional features so that the view can give different types of charts
