Valerie Junk demonstrates a process:
In this tutorial, I will recreate a project I built last year: a mini Power BI dashboard with a toggle button to change its appearance. When you toggle the button, the background color changes, the logo and snow switch images are updated, and the visuals are restyled accordingly (including the color of the trees).
This project combines different tutorials I created in the past, which cover dynamic color changes and the lollipop visual.
At the bottom of this page, you will find a step-by-step video, and you can download the file from the download page.
