All in Tableau How-Tos

How do you approach a new data set in Tableau? Do you spend a while studying the fields and data types? Or do you Google what other people have built using similar data? Maybe you like jumping straight into building to see how things shake out?

I lean toward the latter. Building visuals allows you to learn the data quickly, develop insights, and expose data issues (let's be honest, there are almost always wrinkles to work out of the data).

Let me guess, you have a value (maybe a null) displaying in a Tableau filter and you want it to go away? You don’t want to leave it just sitting there because it’s ugly and your users are insatiably curious. You know if you leave it they are going to select it and you’re going to have to answer questions about what this “null” value means and why it’s a filter option.

Sometimes, you need a totally customized date filter for a Tableau dashboard. A fully customized date filter allows you to list the exact date ranges you want a user to be able to select from, and then filters the worksheets in the dashboard to that selected range. Check this video out to learn how you can utilize a parameter, calculation with date logic and worksheet filters to give your users a fully customized list of date ranges they can select and filter on.
