Building data metric objects through user interactions with data marks of displayed visual representations of data sources

摘要

A method visualizes data sources. A user selects a data source, and the computer system displays a first data visualization according to placement of data fields in shelves of the user interface. The data visualization comprises visual data marks representing the data source. A user selects some of the data marks. In response, the system displays a metric window including a data metric object preview, a summary of the selected data marks, and setting controls. The user provides input to create the data metric object. In response, the system creates the data metric object, including: configuration parameters derived from the first data visualization; an initial extract from the data source according to the configuration parameters; and a schedule for recurring retrieval of data from the data source to update the extract. The system then displays a second data visualization according to the configuration parameters and the extract.
