Read More5 things I wish I knew about Tableau when I started
From day one of using Tableau, I found it to be a fantastic and easy way to visualise my data and produce great reports and analysis. 3 years on, I have come to learn and understand a few of the more advanced features and concepts about Tableau which have really enhanced the way I use it today. If I could visit myself 3 years ago and teach 5 Tableau concepts, this is what I’d cover. Green vs Blue Green data fields are continuous and blue data fields are discrete. Tableau behaves differently depending on which of these different types of fields are used in a view. I’m not going to go into too...
Read MoreMaintaining percent of total whilst filtering
Tableau makes it really easy to switch from showing absolute figures to a percent of total figure by using the Quick Table Calculation option. However, if you want to filter out one or more of your dimensions, the percent of total figure changes because the ‘total’ which is used in the computation changes too to reflect the loss of the dimension members. In some cases, you will want to maintain the original percentage (of the whole underlying data) whilst just displaying the dimension members you are interested in. This post examines 3 different ways to accomplish this, along with why you...
Read MoreWhy is my Tableau viz slow?
We all know and love Tableau to be the best BI tool to enable you to quickly and easily see and understand your data. It enables fantastic ‘speed of thought’ analysis, super-fast data visualisation on giant data sets and is often heard in the same sentence with many other superlative prefixed buzzwords. But sometimes, just sometimes, you can get stuck in a rut with a slow workbook if you’ve been overzealous on the features or have configured things in the wrong way. This post is about what you can do to help get your viz back up to the ludicrous speed you expect. There are several separate...
Read MoreCharting account balances in Tableau
I’ve seen a couple of questions recently on how to visualise account balance data whilst still being able to use the date aggregation in Tableau. Because balance represents a snapshot in time, it is nonsense to sum up all the balance values over a year or a month. The average or maximum or minimum over a period might be useful but what was really wanted was the balance at the end of a certain time frame – i.e. balance at the end of 2009, balance at the end of February 2010, the balance at the end of Q3 2007 etc. This post looks at one way to achieve this using a table calculation called...
