Microsoft frequently adds new features that are available for preview in Power BI. This is a way for Microsoft to launch the features and have them tested by the community before making them fully available in the Power BI application. These features are sometimes in preview mode for a long time, and you may find that you want to use one or more of these features before they become generally available.

To activate (or deactivate) preview features, go to … File –> Options and settings –> Options

Then, in the Options window, select “Preview features” (on the left) as shown below.

Then, select the options you would like to activate or deactivate on the right side, such as checking “Shape map visual” to activate it or unchecking “Sparklines” to deactivate it. Once you have selected or unselected all the features you want, then click “OK”. Then, make sure to save whatever you need to, and then close and reopen Power BI for the activations or deactivations to take effect.
