World maps are based on one attribute (country name) and two metrics. They are supported by all Composer data connectors, however the data must include country names to see results.
This topic describes:
- Configuring Default World Map Settings for a Data Source
- Configuring Colors for a Specific World Map
- Understanding Visual Color Condition Thresholds
To configure default world map settings for a data source configuration:
Edit the appropriate data source configuration. See Editing a Data Source Configuration.
Select the Visuals tab in the data source configuration wizard.
On the Standard subtab of the Visuals tab, select Map: World Countries.
If you want to be able to display the data collected by this data source configuration as a world country map, make sure the Map: World Countries checkbox is selected.
Default world country map settings appear on the right side of the page.
Configure the default settings as follows:
Setting Description Country
Select the country attribute that should be used for world maps with this data source.
Country Limit Specify the maximum number of countries for which results are shown. Note that the default limit (50) is smaller than the number of countries in the world. So some countries will not be shown unless you increase this limit. Country Sort Select a metric or attribute by which the country attribute should be sorted. You can also select the sorting order (Ascending or Descending). For metrics, you can define the default aggregation function: SUM, AVG, MAX, or MIN. See Available Metric Functions. Volume Select a volume metric for the map. You can also define the default aggregation function used for the metric values: SUM, AVG, MAX, MIN, or (for some data sources) LAST VALUE. See Available Metric Functions. Color Specify the metric that should be used to determine map colors. You can also define the default aggregation function used for the metric values: SUM, AVG, MAX, MIN, or (for some data sources) LAST VALUE. See Available Metric Functions. Tile Provider Select a tile provider. By default, OpenStreetMap is selected. Tile Provider API Key For MapQuest, MapBox, and CloudMade tile providers, specify the Tile Provider API Key
To specify the color settings for a specific world map using the Color sidebar:
Edit the visual you want to modify. See Editing Visuals.
If you are editing the visual in a dashboard, select Edit Visual from the visual drop-down menu. The sidebar menu for the visual appears. If you are editing the visual from the Visual Gallery, the sidebar appears to the right of the visual.
Select on the sidebar menu. The Color sidebar for the visual appears.
Configure the color settings as described below. As you change the color settings, the legend at the top of the Color sidebar shows how the legend will appear on the visual. Supported color specifications are described in Specifying Colors.
Setting Description Legend Slide the bar to the right if you want the legend to be displayed on the visual or to the left to hide the legend. Color Metric Select the metric that affects the segment color in the visual. Color Palette If a color palette is specified for this visual type in the data source defaults, select the color palette for this specific visual. If a color range is selected for visuals in the data source defaults, this setting is not available. Color Mode
Select Distinct Colors or Gradient to identify the way colors are used on the screen. Either specific distinct colors will be used or a gradient of colors will be used.
(This is equivalent to the Legend Type default settings on the Visuals tab of the data source configuration.)
Threshold Mode If you selected the Gradient color mode, this setting cannot be changed. If you selected the Distinct Colors color mode, select either Auto or Manual from the drop-down list. Auto will automatically assign thresholds and colors for the visual. Manual allows you to change the thresholds and colors used on the visual. Number of colors Specify the number of colors to use for the visual. Color Rules Color rules allow you to change the colors for each color used for the visual. In addition, if you specified a Manual threshold mode, you can select the thresholds used for color settings in the visual. See Understanding Visual Color Condition Thresholds.
Close the Color sidebar and the color settings are dynamically applied to the visual.
Select to save the dashboard and the visual with its updated settings.
You can set threshold color conditions for metric-based visuals. At least two color settings are required. In addition, thresholds are specified between each color setting. (So three color settings require two threshold settings; four color settings require three threshold settings, etc.)
The color for Color 1 is used when the value of the color metric is less than the first threshold value.
The color for Color 2 is used when the value of the color metric falls between the first and second threshold values.
If only three colors are used for the visual, the color for Color 3 is used when the value of the color metric is greater than or equal to the second threshold value.
If more than three colors are used, the color for Color 3 is used when the value of the color metric falls between the second and third threshold values.
When more than three colors are used, the colors continue to be applied in this pattern for all threshold settings; any color metric values greater than the last threshold setting have the final color applied.
You can have Composer automatically set the thresholds or you can manually set them.
