Interacting with Level of Detail Calculations

Level of Detail calculations are really important in Tableau and can provide a suitable alternative for handling the granularity/aggregation trade-off, when visualizing data in different layers. Below, you can follow the link, to such an endeavor:

Animations with Tableau

Animations in Tableau can prove to be quite useful, especially if you want to observe a change over time. In the sample data set that I used, I was able to observe how the life expectancy, as a function of fertility rate, changed from 1960 to 2013, in a powerful visualization. The end result, dashboard is viewed below:

Advanced visualization techniques in Tableau promote an interesting story

This project was quite challenging, but I have to admit that analyzing data through Tableau is a process that never ceases to amaze me. From advanced table calculations, to reference and trend lines, this Tableau workbook summarized the analytical power of Tableau and allows for some awesome and actionable insights. You can download the workbook from my public profile and view the story in full screen mode (F7), by following the link below:

Creating and Saving Advanced Table Calculations in Tableau

Advanced table calculations in Tableau can become really handy when visualizing data. The tricky part lies within the ability to save a table calculation you use in the visualization part, to utilize it again, in a different context or format. This can happen, by dragging the table calculation view that you have achieved, in the measure’s pane. Then, a new measure is being created for further usage. The link below shows such an endeavor in Tableau Public (my public profile):

An interactive dashboard in Tableau

Combining techniques like groups, sets, parameters, crating folders, default properties for fields, using two dimensions as a color, adding reference lines, drop lines and enhancing the tool tip, assisted me to create a highly interactive dashboard, in order to get the necessary information about the highest performing startups, derived from an imaginary data set.
