In one of my previous post,s I wrote about Dynamically Update the ‘Relative to’ section of a Table Calculation, using a parameter. Now with the release of Tableau 2019.2, and the introduction of Parameter actions, it is possible to dynamically select a member of a dimension as the ‘Relative to’ part of a Table Calculation. In this blog post, I will explain how to achieve this result.
Last weekend I've participated in an event taking place at the data school, called DataDive. The event was organised by DataKind, a non-profit organisation which aims to help other charities using data. To do so they recruit volunteers which participate in a Hackathon style event, where they clean, analyse and visualise data.
Tableau dashboard offers the ability to apply filters onto the view. Usually, this appears by dropdown, slider, or tick boxes. Wouldn’t be nice to have buttons with this functionality instead? In this blog post, I will explain this process step by step.
During the latest DS client project, I have implemented a functionality that allows highlighting a certain number of marks (in this example a Top-N bar chart) and dynamically displays the cumulative weight of these highlighted marks as a percentage of the total. In this blogpost I will explain how to achieve it.
Before joining the DS I remember reading Dashboard Weeks posts in the blog, and often I came across articles about challenges using another visualisation tool than Tableau. The last articles I remember were based on PowerBI, so I was expecting that one of our Dashboard week day would be based on this software.
Instead, Andy and Carl managed to surprise us once more...
Some types of table calculations allow the end user to define what the calculation is relative to.
This choice can be done from the Table Calculation pop-up, or by right clicking on the specific measure pill. But how can you make this choice dynamic? perhaps controllable from a drop-down menu?
At the end of my latest blog post, Dashboard Week Day 1: NHS Trusts, I wished that our next challenge for Dashboard week would be more concentrated on design.
It seems like my wish came true, since Andy for today task, asked us to create an infographic dashboard using data on The Avengers comic books series.
For the first day of our Dashboard week, Andy challenged us to gather and analyse data on the spend over £25K at NHS Trusts.
The data was scattered over 391 different URLs, each containing multiple files (often in different formats)
