In the Attribute coverage section, you can see what values your data set contains. The coverage is a graphic representation of the occurrence of attribute values in your data set. This display is hierarchical, as most data sets are. Click «Expand all» to view all attributes in each data set. Click «Collapse all» to collapse the attribute list. Click the chevron next to the data set name to expand and collapse each data set separately.
Attributes are visualized with a graduated color bar which classifies the occurrence of attribute values into intervals.
Hover your mouse over the intervals in the graduated color bar to display the value, occurrences and percentage of the attribute, within the interval.
