Abstract: An electronic device displays a chart, which includes a first set of visual marks that represent values derived from a set of data. The device concurrently displays a chart-calculations-options area. The chart-calculations-options area displays a first plurality of options for type of calculation. The device detects user selection of (i) a first option, from the first plurality of options, for type of calculation and (ii) a second option corresponding to a parameter for the selected first option. In response to detecting the user selection, the device visually distinguishes visual marks in a second set of visual marks in the chart. The second set of visual marks is distinct from the first set of visual marks and corresponds to the first option for type of calculation and the second option corresponding to the parameter for the selected first option.

Abstract: An electronic device displays a chart, which includes visual marks that represent calculated values derived from a set of data, and panes formed by intersection of rows and columns. A current focus is on a first visual mark at a first position. The device concurrently displays a chart-calculations-options area, which includes display options for the type of calculation and the type of data partitioning. Visual marks in a first set of visual marks are visually distinguished from other visual marks. The first set of visual marks includes the first visual mark, and corresponds to a first selected option for the type of calculation and a first selected option for the type of data partitioning. The device detects an input that selects a second option for the type of data partitioning. In response, the device visually distinguishes visual marks in a second set of visual marks in accordance with the selection.

Abstract: A computer system displays a graphical user interface that includes a data visualization region, a shelf region, and a schema information region. The computer system receives a first user input to place a first dimension data field from the schema information region into the shelf region. In accordance with the first user input, the computer system determines a visualization level of detail that is based on at least the first dimension data field. The computer system receives a second user input to specify a first aggregation. The first aggregation has a custom level of detail that is distinct from the visualization level of detail. The computer system builds a visual specification that includes the visualization and custom levels of detail. The computer system generates a data visualization corresponding to the visual specification and displays the data visualization in the data visualization region.

Source fields may be determined based on the records and the source fields may be displayed in a source panel. A data model that includes a source data object may be displayed. Relationships between the source fields may be determined based on values in the records. In response to providing a relationship between the source fields, a data object that includes a key field and one or more data fields that correspond to the relationship may be generated. The data model may be modified to include the data object and to remove the source fields that correspond to the data fields.

Abstract: A method displays a graphical user interface for a data visualization application. The user interface includes a schema information region that includes fields from a database. A user specifies a first aggregation using the interface. The first aggregation groups by a first set of fields and specifies an aggregated output field. The user also specifies a second aggregation. The second aggregation references the first aggregation and groups by a second set of fields. The set may include the aggregated output field. The second set is different from the first set. The method builds a visual specification based on the first and second aggregations. The method may retrieve tuples of data from the database using database queries generated from the visual specification, where each tuple includes data calculated based on the second aggregation. The method may display a data visualization, including the data calculated based on the second aggregation.

Abstract: Welding system and method permit exchange of data with Smart Grid monitors and/or controllers. The welding systems include a welding power supply configured to convert power between the power grid and the welding power supply.

The control circuitry may control operation of such devices, the exchange of power between them, and the draw of power from the grid or the application of power to the grid based upon the data exchanged with the grid monitors and/or controllers.
