‘The enormous multiplication of books in every branch of knowledge is one of the greatest evils of this age; since it presents one of the most serious obstacles to the acquisition of correct information by throwing in the reader’s way piles of lumber in which...
While teaching an Advanced Tableau session in Washington DC last week, we ran across a great little puzzler that highlighted to me the value of discussing data structures. Working from one of Tableau's standard data sets, the Superstore, the question was "Can we use Tableau to...
As with all things Tableau, some of the more surprising tricks happen when you’re asked a seemingly simple, yet surprising, question. In this case, it went something like this: ‘Yes, the line chart is good but can we get a ‘fake’ line in there that is...
Have you locked yourself out of your Vertica cluster, but still have SSH or console access to the servers themselves? If you're using the default authentication method (not LDAP/Kerberos/GSS), you can temporarily use the "trust" Vertica client authentication method and reset the password. The steps...
If you’ve ever wanted to be able to send an email to a colleague because the dashboard you’re viewing in Tableau is just too good to pass up, this might help you out. In the following dashboard, we’ll accomplish a few things: 1.) Use URL actions to...
Heading to my house in Durham, North Carolina and looking forward to a long bike ride and fresh peaches at the market. Spent this last week in New York City working with a great client with some true Big Data; as part of a follow-up...
Kickstarter has been making waves in recent months as the premier place for crowd funding. Projects range from big to small, from purely entertainment to potentially life changing. There’s a lot to love about this dream factory. However, there’s been controversy as well. All projects are not always what they appear...
It should come as no surprise that data is not always as it seems. Well, maybe not that big of a surprise to the data analysts out there. After all, most of us are swimming in data. And it might not have had time to...
It's common for Tableau Server users to want to embed content into a separate web application while maintaining tight security restrictions. If you want your web application to handle all of the authentication, it's possible to use the trusted ticket authentication system offered by Tableau...
In my last post (Part 1) I showed you how to create a combination area fill & symbol map. Last week a client in Washington, DC asked me if it was possible to create these types of maps and display specific regional groupings of states. The...
Building on the KPI tutorial from Tableau found here, I would like to add a neat trick to increase your data-pixel ratio and remove additional clutter from your KPI charts by using a custom shape. The premise is based on Stephen Few and Edward Tufte's...
Loading data into Teradata can be done quickly and fairly easily using the Teradata FastLoad utility, but the utility isn’t exactly friendly to new users. This article provides a quick introduction into the FastLoad utility, which is included in the free Teradata Tools & Utilities...
Fresh off a West Coast swing that took me from the Central Valley to Silicon Valley and into San Francisco, I'm back in Oklahoma for Independence Day. This quick blog post explores a question that always comes up during Tableau Training sessions - "What locations can...
While in Chicago conducting a training last week a client asked me whether you can offer a hide/show option for reference lines on a published dashboard. My immediate thought was Tableau doesn't have a native option to support this, but quickly my mind turned to...
Last week, a client in Washington D.C. (and several clients before) have asked me about building combination maps that combine the new filled map style with the symbol map. This is not a Show Me option but is pretty easy to do once you understand the...
Managing Tableau Server security can be a lot of work, especially when you're dealing with tons of users from all over the enterprise. Fortunately, Tableau has an easy way to set this up once and let users manage it themselves using Active Directory Groups (aka...
At 27,000ft on the way home from the Big Apple (New York City) with another quick blog post. No mud, barbed wire, or fire pits here, sorry to disappoint. I had a question come in about Multi-Measure Dual Axis Charts and I thought this might make...
I’m confident the sudden, all-encompassing change in pace for ‘data’ over the last few years has been fueled by our need to want more information out of our world. The immediacy and sheer speed with which it arrives is faster than most of us have...
I was writing a query today and came across a set of data with an annoying leading space. Or what I thought was a leading space. My first instinct was to throw this around my field: LTRIM(RTRIM([SKU])) But the space was still there. OMGWTFBBQ! After...
What do Tableau Software, Business Intelligence and User Experience have in common? Combined, they represent the New Age of Data. More specifically, they push data visualization, data personalization and data emergence to higher levels of understanding. At the present moment, we are seeing a massive...
