Tableau, Data Analyse & Visualisatie
A couple of years ago, Tableau introduced one of its most highly requested features ever: Dynamic Parameters. This feature made it possible to populate a parameter with values directly from a data source, rather than being limited to static, manually entered values.
This works great, but as soon as this was available a new request came up: adding manual values to the list – especially the ‘All’ value.

Instead of forcing them to view at a certain chart type, you can give them the option to chose between different visualizations- bar charts, line charts, etc, or variations on a chart, based on their need, or preference.
Data Visualization is about visualizing data the right way.
Interactive business dashboards tend to have a special challenge: the must display data with accurate labels, regardless of how the data changes from day to day. Many infographics visualizations are using static data – and therefor the labels can be put on the most convenient location. But what happens when the data changes – either due to new data, or filtering? Labels will overlap, disappear, and/or get mixed up.
The funnel chart is one type of visualization that’s especially prone to this, even with just a few data marks. While working on one, I came up with a solution to keep all the labels nice and clear, no matter what the data throws at it. Bonus: it’s flexible enough for easy customization!

Tableau makes it really easy to create a minimalist dashboard – and tooltips are a great way to unlock the data behind a mark. Emphasizing the datapoint of the tooltip will make the visualization just a little better. And this is even more important on charts with multiple lines.

They display multiple variations of the same chart, often sharing a common axis, which allows for easier comparison across groups.
While effective, these charts can suffer from poor readability if titles are not thoughtfully applied. Let’s look at some ways to enhance labels for better clarity and user experience.
