Before undertaking this module, it is critical that you understand the material covered in the module "Charting with Analytic Tools" and that you have completed the assignment for that module. You must have experience using the analytic tool Tableau Desktop Professional and have the proper software environment installed and available. For software setup instructions, please see the module "Charting with Analytic Tools".
In this module you will learn how to combine charts and other visual elements to create effective dashboard visualizations for organizational data.
Note: While this has changed over time, registration is currently required to view the videos.

Additional ResourcesA dashboard is a visualization of data that combines a number of related charts and other visual elements into an effective display of organizational data. It most often allows the viewer to interact with the data, selecting and filtering as needed.
As we have mentioned before with data visualization, a picture is worth a thousand words. So to understand what a dashboard is, I suggest that you review examples of dashboards from Tableau Software by visiting Dashboard Examples. Click on several of the examples listed and view the entire dashboard. Observe how the charts within the dashboard are related. Observe how you can interact with the dashboard to change the information displayed.
Once you understand what a dashboard is, you need to develop some skill with your analytic tool.
Step 1: To learn about creating dashboards using Tableau software, review the following Tableau video: Dashboard Development (13:43)
Once you have some skill with your tool, you need to be able to apply your tool to make, not just any visualization, but rather, effective, clean and clear visualizations that help your organization understand its data. Analytic tools provide us with so many choices and features but not all choices and features are appropriate for our scenarios. We need to learn to use our choices effectively.
Step 2: Read "Tableau Visual Guidebook". This document is available from the Tableau Software website.
This document will help you to plan your dashboard visualizations and avoid common pitfalls in presenting data.
Step 3: Read "5 Best Practices for Creating Effective Dashboards". This document is available from the Tableau Software website.
This document will further help you perfect your data visualization design.
Note that the following information may also be found in an alternative format in the document: Creating Effective Dashboards Summary.
Here is a short check-list that even professionals can use to review their work.
Chart Type | Consideration |
---|---|
Bar Chart | Does your numerical data fall into categories? Do you have too many categories for the viewer to digest? |
Line Chart | Did you display numerical data over time? |
Pie Chart | Did you show proportions with six or fewer sections? Does the whole have meaning? Beware the pie chart. It can be misleading |
Map | Is geography important? Is it the driver of your presentation? |
Scatter Plot | Do you want to see outliers and trends across variables? Do you want to see a pattern of distribution? |
Gantt Chart | Are you displaying project tasks/schedule? |
Bubbles | Are you using them on a map or scatter plot to show how data is concentrated? |
Histogram | Did you wish to group your data? |
Bullet Graph | Do you wish to show progress toward a goal? |
Heat Map | Do you want to show the relationship between two factors? |
Highlight Table | Did you want a heat map display with numbers? |
