what is a symbol map (dashboard) - Quick BI - Alibaba Cloud Documentation Center

A symbol map marks data points on a map using icons or images. This topic describes the use cases for symbol maps and how to configure their styles.

Prerequisites

A dashboard is created. For more information, see Create a dashboard.
Ensure that the geographic area field you want to add is configured as geographic information. For more information, see Configure a field.
Note
When you add a geographic area field, such as area, to a chart, it is identified as geographic only when the icon is displayed. For a detailed comparison of regions, see public-area-info.xlsx. This table is for geographic area matching only and does not represent the political stance of Quick BI.

Limits

In Area Name mode, a symbol map consists of an Area Name/Dimension and a Tooltip/Measure.

The Area Name is determined by the selected dimension, which must be a single geographic field, such as a province.
The Tooltip/Measure field lets you select from one to five measures to display in the tooltip, such as order amount and profit amount.

If you create a symbol map in Latitude And Longitude mode, the map includes the Latitude And Longitude/Dimension, Location Tag/Dimension, and Tooltip/Measure fields.

For Latitude and Longitude, select one longitude field and one latitude field from the data dimensions.
The Location Tag is an optional dimension whose data type can be string or geographic.
The Tooltip/Measure field accepts one to five measures, such as order amount and profit amount.

Overview

Scenarios

Symbol maps are ideal for visualizing datasets that contain geographic information. They are typically used to show data aggregated by region.

Advantages

Visualization: You can use custom icons or images as markers.
Interaction: You can select and zoom in on the map, switch between measures, and filter data directly within the widget.

Configure styles

This section describes how to configure the chart styles. For information about general style settings, see Configure the chart title.

Geographic Area

Configuration item

Description

Display Range

Supports automatic and custom ranges. In this example, select China.

Note

The map can automatically adjust its display based on the data range. You can also set a custom range. In interactive analysis scenarios, the map always adjusts automatically based on the data range.
The custom display range currently supports global continents and countries, along with regions, provinces, and cities in China.

Turn on Manual Adjustment to automatically generate the current Centroid and Scaling value. You can then modify these values.
