- Displays divided areas or regions on a map.
- Allows you to drill down through your hierarchy data.
- You must add a shape file yourself to use this visual.
This Drilldown Choropleth map shows military veterans by county in the United States.
- Under the Format paintbrush there are several sections available to modify the appearance.
- Under the Data colors section you can adjust the type of colors used on the map and the thresholds that determine their color.
- The Shape properties should really be your first stop when working with this visual. Without configuring at least the Level 1 property with a shape file you will see nothing on your map. You can also change the type of map projection is used here.
- Under the Default color section you can control things like the color of the border between shapes and how thick the line is.
- Using the Zoom properties you can change the behavior of the visual when you zoom into a selection you’ve made or manually zooming on your own.
In addition to these properties you have a set of settings that appears on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
