My fellow colleague Hendrik Kleine taught me another way of creating a donut chart.So today I am posting a variation on the traditional donut instead. We live in the age of gamification and you'll frequently come across a donut representing a single value, making it a KPI viz. In this post, I'll walk through making such a KPI donut, with a twist, each percentage point (out of a total 100) is displayed distinctly.
Tableau forum is a wonderful platform to get the answers to all your tableau related queries. Here, at Tableau Forum, this saying is brought to practicality as users not only learn, but also teach and share ideas with each other further expanding the users’ knowledge base. I truly believe that there are many hidden gems such as small yet valuable Tableau tips and Tricks which are currently hidden in Tableau Forum's Post, I thought of documenting them one after the other so that anyone and everyone can utilise them in their daily tableau work.
There are many different ways of telling a story, but everything starts with an idea.Matt Chambers, data architect at Clemson University who makes complex data easy to understand.Through graphics and other visual strategies, he weaves a story using data. His visualization quickly draw attention to the key messages and uncover surprising patterns and observations that wouldn't be apparent from looking at stats alone .You all probably recognize Matt Chambers’ by his awesome Vizes like "Car color popularity bump chart" .
Tableau doesn’t support 3d graphs because they aren’t consistent with best practices for presenting data in a way that it can be accurately understood. Studies have shown that 3D Charts are less accurate than other visualization types, and Tableau has a strong bias towards accuracy in presentation. No one finds 3D bars, 3D pies etc. analytically useful. On the contrary they make the charts harder to read with no real benefit. So many Viz Gurus advised not to use 3D charts in tableau.
Being a field expert and also being humble is a trait that is hard to come by .One name which came to my mind is Curtis Hariss .A well known face across the Tableauverse.His easy to use, creative and intuitive Tableau Vizes benefited so many Tableau authors around the globe.Curtis always turns complex data sets into beautiful, simple diagrams that tease out unseen patterns and connections.
When the idea of collating a list of Tableau books one should read to get an expertise on the tool came up, it seemed fun in the beginning but not for long. We kept spinning ours pens for some time because every book in the market provides a unique blend of knowledge ranging from a beginner to the masters!! The list kept piling up till we gave up.
I recently had the pleasure of interviewing Michael Mixon, a well known Tableau Viz artist, painter, photographer and traveler.I think you all agree Michael's every project/dashboard is created by design. It is thought out, analyzed and finally, designed and executed.His every dashboard communicates a distinct message.Take a look into his story, where he gets inspiration, and how he uses Tableau and learn more about him.
