Make it easier to switch between raster layers, custom tilesets using expression-based formatting
I just tested raster layers using tiles from MapTiler and was impressed with the result.
Now, the UI for custom map styles and raster layers hard codes a single value for each of these two fields in the visualization's settings:
Power BI is adding expression-based formatting into more and more visuals, to let authors use DAX formulas in visualization settings. My suggestion is to be able to use a DAX formula instead of a hard-coded value in the URL fields pictured above. Said DAX formula would let the author use a disconnected table with a list of URLs, and put these URLs in a slicer to let end users switch custom styles or raster layers.
Below is an example with a choropleth on top of a hillshades raster tileset, this looks real good so why not indulge a bit?
Functional examples of what this means for the end user can be seen here:
