  • The Renderer properties allow you to change the type of maps that are shown, as well as how large each value is displayed and if the value on the map should be transparent. You can also select how you want the aggregated values to be displayed using the Measure property.

  • Depending on the type of map you select in the Renderer section, you will see either settings for Heat map or Contour map. These sections allow you to customize the way the thresholds are displayed for either map style.

  • Under the Animation section, you can control how the visual plays through the results on the visual. The Group field is what is used for the animation.

  • Finally, the Map section allows you to control the interactions users will have with the map. By changing the Zoom and Pan settings, you can turn on/off the ability to freely move around the map.
