Map charts
Map charts are commonly used to compare values and show categories across geographical
regions. Map charts are most beneficial when the data contains geographic information (countries,
regions, states, counties, postal codes, and so on).
Creating a simple map chart
- In the Chart Type section, click the Map
icon.
The canvas updates to display a map chart template.
- Select a service to use for serving map images from the Map service drop-down list. The list provides options that cover specific global regions.
- Select a map chart Type from the drop-down menu. The
following options are available, dependent on the selected chart type:
- Longitude
- Select a variable to serve as the longitudinal value from the drop-down list.
- Latitude
- Select a variable to serve as the latitudinal value from the drop-down list.
- Group
- Select a variable that groups the data point locations from the drop-down menu.
- Category
- Select a column variable that you want to visualize.
- Summary
- Select a statistical summary function (the method that is used for summarizing each category).Two types of statistical summary functions are available. The distinction is important because it determines whether you need to specify a Value variable.
- Functions that do not require a value variable. Functions that do not require a variable. All count and percentage statistics are in this category. These statistics are available when the Value variable is not defined.
- Functions that do require a value variable. Functions that do require a Value variable. For example, the Mean function requires a variable on which the mean is calculated. These statistics are available when the Value variable is not defined.
- Value
- This field displays when a Summary function that requires a value variable, is selected. Select a variable to serve as the value.
- Click the Save visualization in the project control. Select Create a new asset or Append to existing asset. Provide a Visualization asset name, an optional description, and a chart name.
- Click Apply to save the visualization to the project. The new visualization asset is now available on the Assets tab.
