Outlier warning (map)

1. Overview

1.1 Expected effect

The warning color is set according to the smallest dimension area on the map, and this scene is convenient for users to quickly find the area where the warning is located on the map.

For example, the value in Wuxi City, Jiangsu Province is the warning value, and the warning color is "purple". At this time, Jiangsu Province and Wuxi City all display "purple", as shown in the following figure:

1.2 Implementation ideas

Assign the corresponding values under each area of the map, set different colors in different value intervals, and set the corresponding special colors for the warning value, so that the corresponding area in the warning value interval has a special color warning.

1) Use area map for matching, please refer to: area map for details.

2) Set up map drill, please refer to: map drill for details.

3) Drag the indicator to the color attribute bar, and set the color of the value interval.
