Key Takeaways

• 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 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, there are settings that appear on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
