Map Chart

Map charts are used to display geographic data, geographic distribution, spatial patterns, and comparisons between different regions. Map charts combine data with geographic locations, helping to visually understand the distribution of data in geographical space, especially when dealing with geographic areas such as regions, cities, or countries.

Suitable scenarios include:

1. Geographic Distribution Analysis: If you have data from different geographic regions (such as sales data, population data, climate data, etc.), maps can help you visually present the differences between regions. If you want to show the concentration of a certain metric (e.g., sales volume, visit volume), you can use a heatmap to highlight areas with high and low values.
2. Geographic Data Visualization: For example, displaying information such as population density, age structure, education level, and income level across different regions. Maps make it easier to understand and compare these complex data sets.
3. Geographic Trends and Changes: Display the distribution of meteorological data such as temperature, precipitation, wind speed, etc., to help users understand climate changes and seasonal trends.
4. Location Analysis: Analyze transportation costs, delivery times, or transportation routes between different geographic locations. For retailers, food services, and others who need to make location optimization decisions, maps can show the distribution of potential customers, competitors, and geographic advantages, helping to select the optimal location for stores or service areas.
5. Spatial Distribution of Events or Activities: Use maps to display the geographic distribution of historical events, political changes, social movements, etc.

Region

Includes the map used and the corresponding region column from the data.

• Map: select from the built-in maps.
• Region: select the column from the data using the dropdown menu.

Chart/Map

Options include:

• Data: select columns from the data using the dropdown menu.
• Fill: configure fill colors for regions with and without values. When selecting a gradient, the color of regions with values will be filled with different depths based on the values.
• Stroke: configure the stroke for the region. You can set the color, thickness, and line style (dashed, etc.).
• Label: by default, labels are not displayed. When selected, you can configure the color and font size.

Layout

Includes:

• Scale: configure the zoom level of the map, default is 100.
• Offset: configure the offset in both the X and Y axis directions.
• Graticule: configure whether to display the latitude and longitude lines on the map, typically used for world maps.

Description

Used to configure the display of supplementary information for the chart.

• Title: configure the title of the chart, located at the top of the chart.
• Description: configure the description of the chart, located below the title.
