Show Me How: Area charts (continuous)

In this post in the Show Me How series we will discuss continuous area charts. We will try to find a good use case for them, see how they are created in Tableau with and without the Show Me panel and look at them from the angle of data visualisation best practices. Before we jump into the theory, I have to emphasise the importance of understanding what continuous and discrete means in Tableau. We have addressed this before, you will find good descriptions in our earlier blog post here or information about blue and green pills here.   Show Me continuous Area Charts We find in Wikipedia...

Switching between different (units of) measures in a view

Tableau is a very flexible tool, it allows us to display the same data content in various ways. One of the countless examples of this flexibility is that we can show measures in separate views or we can include many of them in the same view, enabling the user to switch between the measures. While parameters make this switch easy, if those measures have different units, moreover, we want to colour the values based on varying rules, involving them in the same view gets a bit more complicated. We do not discuss now the basics of how to create this ‘measure switch’  with a parameter...

Show Me How: Dual Lines

In this post in the Show Me How Series we’re going to talk about Dual Lines. Why use them, how to create them without Show Me, and why they might not always be appropriate as visual best practice. Show Me Dual Lines Using Show Me to create Dual Line charts is straight forward, however first we need to remember the lessons from our post on Continuous Lines – Dual Lines are merely an extension of those. The key difference –  we need at least two measures obviously. Let’s look at the difference in the results, I’m using Superstore Sales and Order Date –...

Tableau 9.0 out today

There’s a lot of excitement at The Information Lab Towers, with the news that Tableau 9.0 has officially released today. We won’t go into chapter and verse on all the new features – Tableau’s website already does a great job of that – and I even wrote a blog post on some of the lesser spotted enhancements we can look forward to. Suffice to say, the introduction of new features like smart maps, automatic data prepping, instant calculation editing, LOD calculations, Regex expressions, not to mention some huge strides in improving performance, will no doubt have...
