Tableau Dashboard:

The dashboard is a collection of worksheets allows analyzing multiple views at once. The dashboard consists of size, sheets, objects, tiled, dashboard.

Types of Dashboard are

  1. Explanatory Dashboard – They are static.
  2. Exploratory Dashboard – They are interactive.
  3. Explanatory/ Exploratory Dashboard- Includes both annotations and interactive controls.
  4. Story Telling dashboards – Convey series of events

Dashboard actions (provide flexible interactivity) are the key features. They allow the worksheet to work outside the domain of the view. There are 3 types of actions: Filter actions, Highlight actions, URL actions.

Purpose of Creating a Dashboard in Tableau Desktop

Users like to see some of the views on a single page to save time. While creating a new dashboard, data pane is replaced with a list of worksheets. Having a dashboard supports bi-directional communication between dashboards and source sheets.

Objects can be added by simply dragging them to the dashboard, by default they are added as ‘Tiled’. Tiled objects are the best in adding worksheets to the dashboard. The dashboard can be sized based on the following options: Automatic, Exactly, Range, Pre-sets.

The Layout tab allows setting the dimensions and location of individual components. The sizes are in the pixel. The major component of the dashboard view:

  • The list of worksheets
  • Dashboard objects to add
  • Tiled versus Floating Objects
  • Dashboard Layout outline, size control
  • The dashboard Itself

Advantages and Disadvantages of Tableau Dashboard

Below are the pros and cons of Tableau dashboard which are as follows:

Advantages

  • Centralized Data visualization
  • Ease of Implementation
  • Quickly create an interactive visualization
  • Can show a large amount of data
  • Mobile support
  • Responsive dashboard
  • Descriptive Texts
  • KPI’s (Key Performance Indicator) and metrics
  • Multiple annotations
  • Filters
  • Sweet Action
  • Multimedia

It is possible to enable a live website in a dashboard by dragging the web Page Dashboard object onto the canvas.

We can add Dynamic Google Maps satellite images to the dashboard by choosing the dashboard file menu, click Actions Then add action button and choose URL. And adding youtube videos to the dashboard (need a spreadsheet to add all the videos). We can add filters to the sheets available in the dashboard to be more interactive by selecting the drop-down options ->all data sources. Applying single filters to all sheets, Dashboard-> actions.

Disadvantages

  • No custom visual imports
  • Limited column table
  • Static and single value parameters
  • Limited data preprocessing
  • Scaling issue
  • Is Expensive

Limitations of the Tableau dashboard

Screen resolution on tableau dashboards gets disturbed if the developer’s resolution is different from end-users’ strengthen dashboards are not responsive. When comparing two bars, the number on the axis can be used to give large differences. If we want to refresh the data we need to re-run the flow.

  What is Tableau Line Chart? The Tableau Line Chart is a visualization option where the two axes of a graph represent the dimension ( like time) and a measure ( like say sales of a company) are plotted together. This generates points known as Markers. By joining all the points together a line is formed which represents a trend or any useful insight. Image Source Types of Tableau Line Charts: Simple Line Chart Choose one dimension and one measure to create a simple line chart. Drag the dimension Ship Mode to Columns Shelf and Sales to the Rows shelf. Choose the Line chart from the Marks card. You will get the following line chart, which shows the variation of Sales for different Ship modes. Multiple Measure Line Chart You can use one dimension with two or more measures in a line chart. This will produce multiple line charts, each in one pane. Each pane represents the variation of the dimension with one of the measures. Line Chart with Label Each of the points making the line chart ...
