Built-In Tracker
Note: the horizontal display is always used on mobile devices (to preserve space) AND in the built-in locations on sites using Snapshot or Poster 2.0 templates.
If you want to display the traditional "thermometer" style display, use the Classic Homepage template and/or use the Embeddable Tracker Settings to generate an Embed code to place in any "custom text space" on the event site or in the source code of a different website.
