The range of the gauge can be set in the Tile Configuration (right-click on tile -> Configure Tile).
The gauge view will change based on the dimensions of the tile. A square or near-square dimension will show a half-circle gauge. A short, wide rectangle dimension will show a single, horizontal bar gauge. A tall, narrow dimension will show a vertical bar gauge.
For small tile sizes, the last value and range text is removed from the tile view. These values can be seen on hover.
There are no available color options for the gauge view yet. This option is coming soon.
