Feed: What's New. Author: Andrew Beers. The right mindset is about changing the DNA of how people think about and behave around data when it comes to decision-making. With the right mindset, data permeates all aspects of the business. Everyone, regardless of role or rank, prioritizes data-based insights over intuition. People focus on measurable outcomes, digging deeper into data to understand what drives results. They challenge ideas with data-based experiments to drive new innovation. Successful leaders embrace this shift in how people think, speak and act around data. As people become more comfortable working with data, they seek new and ... Read More

Feed: What's New. Author: Amanda Makulec. Most iterations of flatten the curve focused on showing two curves and a dotted line for healthcare capacity. These simple versions of the chart allow us to focus on the peak and whether it exceeds the line for capacity. Those curves plotting new cases don’t exist in a vacuum though. Animations and more complex iterations of the infographic (like this animation by Alexander Radtke) highlight the various factors that can shape the curve. An unscientific illustration of the many factors influencing the shape of the curve of new COVID-19 cases and the reference line ... Read More

Feed: What's New. Author: Eillie Anzilotti. The coronavirus is spreading quickly through the United States, and many elected officials across the country are reacting with policies designed to slow the transmission of the pandemic, otherwise known as “flattening the curve.” One of the key methods they’re encouraging is social distancing—the practice of people limiting their movements and contact with others to limit the possibility for the virus to jump from person to person. Since it was used effectively during the flu outbreak of 1918, social distancing has been widely agreed upon as one of the strongest collective actions we can ... Read More

Feed: What's New. Author: Geraldine Zanolli. Last year, we released the Connector SDK that allows developers to build native-looking connectors like the Databricks Connector. In Tableau 2020.2, we are adding v2 of the Connection Dialog, a new feature which enables a more data-driven dialog for connector plugins. Currently, developers are limited when building the connection dialog, which prompts a person to enter details that will be used to set the connection. With the latest version of Connection Dialog, developers can easily add new custom fields to the dialog or ask for any other information they need to help people connect ... Read More

Feed: The Information Lab. Author: anna.prosvetova. 28 March, 2020 | Anna Prosvetova New feature in Tableau Prep Builder 2020.1: Fixed Level of Detail expressions Tableau Prep Builder 2020.1 was recently released, and it now supports Fixed Level of Detail (Fixed LOD) calculations, similar to Tableau Desktop. That means that you can use them to change the granularity of fields in your data, or create new fields using the existing data in your dataset. Doing such calculations before bringing the data into Tableau Desktop will improve a dashboard’s performance, especially when working with large datasets. In this blog post I will ... Read More

Feed: What's New. Author: Andy Cotgreave. In my section, I looked at how a chart itself can become a virus: starting in an academic setting, in this case with the CDC’s March 18th report on the outcomes of 4,226 COVID-19 cases in the US, and evolving into a variety of angles from news sources, and then onto social media. I showed how unequal age bands and a large amount of missing data were easy traps and might confuse people reading quickly and looking for something to share on social media. These traps don’t make this a bad chart: the CDC ... Read More

Feed: The Information Lab. Author: andrew.lehm. 27 March, 2020 | Andrew Lehm How to action filter when using set/parameter action drill-downs in Tableau I really like set and parameter action drill-downs on a dashboard – when used well, they can help to add granularity to the data specific – user-selected – categories, where adding all of the data would overwhelm and dilute the original message. However, I struggled for a while to incorporate them into dashboards where I was using action filters between sheets. Sometimes everything worked fine, but every now and then I would get some behaviour that would ... Read More

Feed: What's New. Author: Geraldine Zanolli. We are announcing the #DataDev Site Challenge, three months of fun challenges for all. And obviously, we want to reward our community for achieving these challenges with exclusive #DataDav Swag Packs! There are 18 challenges in total. All the challenges are categorized (Extensibility, Automation/Integration and Embedding), and have different levels (easy, moderate, and advanced). Developers have two weeks to solve one or more of each set of new challenges. At the end of the two weeks, we will host a “How to” webinar to spotlight what someone from the #DataDev community has built before ... Read More

Feed: What's New. Author: Kyle Gupton. Our primary focus for accessibility has been to enable Tableau authors to create dashboards that are accessible to people with disabilities. Over time, we’ve been expanding the functionality that authors can use in dashboards that they want to be more accessible. Perhaps my favorite new feature we’ve added to Tableau in the past couple of years is dashboard extensions. Extensions allow developers to add new capabilities to Tableau dashboards beyond those built into the product. One of the (many) cool things about dashboard extensions is that they are just HTML pages hosted in a ... Read More
