Hi Tableau Community!


Welcome to another edition of our weekly digest. As spring has arrived for much of us here in the northern hemisphere I thought it appropriate to share a viz on pollen.  I love spring when the days grow long and the buds on the trees hint at leaves to come. Here in Seattle, nearly every street is covered with cherry blossoms and magnolia petals! This is lovely, albeit foreboding, as with these blossoms comes pollen. Pollen that makes you sneeze, your eyes puffy, and fills your head with congestion. Seasonal allergies seem to sneak up on me every year, so with sympathy for my fellow afflicted friends, please enjoy this brilliant viz, Paris "City of Pollen" A geographical analysis of pollen from Rondeau Mathieu :



William Faulkner wrote, "Sometimes I think there must be a sort of pollen of ideas floating in the air, which fertilizes similarly minds here and there which have not had direct contact." That is a poetic way to think of how we all share information and ideas across our wide and diverse community. I will try to remember that while I take my anti-histamine and hope for rain Have a great week and please enjoy the rest of the digest!

Top-Voted Idea


This week our top-voted idea is Allow users to set bar, line, shape, and padding widths by pixels or percents. This was just posted on March 28th by Skylark Macadamia and already has 16 votes. In the text they share, "Currently Tableau offers limited control over chart design. Allowing users to set exact pixel widths or percentages for bars, lines, shapes, and padding within charts, will allow greater design precision and lead to cohesive designs within dashboards. Allowing users precise control over these features will also help them conform dashboard designs to existing brand guidelines." If you agree that this is needed click on the link and up-vote the idea.

Most Talked About Thread

Our most talked about thread this week is on Joins in Tableau by Twinkle Bansal . In the initial thread, they shared, "Actually table '_users' is not having direct join with table '_projects' so I joined that one with table 'sites' and wrote below query. But again and again am getting error 'Invalid FROM Clause near table _users':" ... it continues from there. The author is using PostgreSQL and involved some but not all users having access to the particular project. Ari G was able to help Twinkle to a solution and shared details in the thread.


There are numerous threads in the forums on users have trouble with joins both in Tableau Desktop and Prep. Many of the common questions have been solved so we encourage you to search through the forums for a solution before posting a question. The answer to your question may very well be already posted and this is a great opportunity to learn more with Tableau!



As we will continue to share, in the Tableau Forums, we frequently request those who post questions to attach a packaged workbook. This document is to help you understand when a packaged workbook helps, why we ask for it, and how to include one: Packaged workbooks: when, why, how . Please bookmark this resource!


Community Highlights


+ Tableau Forum Ambassador Jim Dehner has started to use his Tableau Public site as a library where he is documenting different approaches to frequently asked questions (FAQs) in the forum. Some include"how-to" instructions or can be reverse engineered to help users learn. There are nine examples so far - check them out here: Tableau Public


+ Tableau Public Ambassador Rajeev Pandey shares how to create a block bar donut chart in a recent blog post and in support of the #PreppinData challenge from Tableau Ambassador Carl Allchin and Jonathan Allenby he wrote a piece encouraging readers to "Think About Your Data Holistically." Enjoy!


+ Speaking of #PreppinData: Check out the fill site and all the weekly challenges here: Preppin' Data. On this site Carl and Jonathan provide a weekly challenge to manipulate a data set that they provide into an output they will publish. On the following week, they will add the solution file to the previous week's folder and set a new challenge. This is a great resource for everyone using Tableau Prep!

+ Zen Master Ken Flerlage posted a blog on how to create a date scaffold in Desktop and Prep here: Creating a Date Scaffold in Tableau . This was inspired by seeing a common problem in the Tableau Community Forum of missing dates. He shares, "For instance, you may want your visualization to always show all twelve months of the year, regardless of whether or not there is data for all twelve months. Quite often, the solution to these problems is to use a date scaffold. So, in this blog, I’m going to show you how to create and use a date scaffold in Tableau." This is a great resource and inspired by the work of many others. Ken's blog provides attribution and a detailed step-by-step guide.
