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 a type of calculation and a 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 a type of calculation and a first selected option for a type of data partitioning. The device detects an input that selects a second option for a type of data partitioning, and, in response, visually distinguishes visual marks in a second set of visual marks in accordance with the selection.

Abstract: A method is performed at an electronic device with a display. On the display, the method displays a chart, which includes visual marks that represent a set of data. The chart also includes a first line and/or first band based on data in the set of data that corresponds to the displayed visual marks. The method detects one or more inputs that select a plurality (but less than all) of the displayed visual marks in the chart. In response to detecting the one or more inputs, the method displays a second line and/or second band based on data in the set of data that corresponds to the selected plurality of the displayed visual marks and maintains display of the chart and the first line and/or first band in the chart.

Abstract: A chart has visual marks representing a dataset and displays icons, each icon specifying a line or band calculation based on the visual marks. The method detects input on a first icon while concurrently displaying the chart and the icons. Upon selection of the first icon, the method displays option icons according to the first icon. Each option icon specifies a different way of applying the first line or band calculation to the displayed visual marks. The method detects movement of the first icon to a first option icon. The first option icon specifies a first way of the applying the first line or band calculation to the displayed visual marks. Accordingly, the method performs the first line or band calculation on the displayed visual marks in the first way to form a line or band, and superimposes the line or band on the chart.

Abstract: A method displays a chart including visual marks representing a dataset. The chart is displayed according to contents of multiple shelf regions. The shelf regions determine characteristics of the chart. The method generates a visual analytic object by applying an analytic operation to the set of data represented by the visual marks, and displays the visual analytic object superimposed over the chart. The method detects user input to select the displayed visual analytic object and place an icon representing the visual analytic object onto a first shelf region. In response, the method updates the content of the first shelf region to associate it with the analytic operation corresponding to the visual analytic object and updates the chart according to the updated content of the first shelf region. This includes updating the chart based on values of the dataset represented by the visual marks relative to the analytic operation.

Abstract: A method executes at an electronic device with a display, concurrently displaying a chart that displays visual marks representing a set of data and a plurality of analytic icons. The method detects a first portion of an input on a first analytic icon, and in response displays one or more option icons that correspond to options for performing a first analytical operation that corresponds to the first analytic icon. The method also detects a second portion of the input on the first analytic icon and in response moves the first analytic icon over a respective option icon such that the first analytic icon is over the respective option icon immediately prior to ceasing to detect the input. In addition, the method adds one or more graphics to the chart that correspond to the first analytical operation and a respective option that corresponds to the respective option icon.

Abstract: The process receives a visual specification, which specifies data sources, visual variables, and data fields from the data sources. Each visual variable is associated with one or more data fields and each data field is either a dimension or a measure. For each measure m, the process identifies a set R(m) consisting of dimensions that are reachable from the measure by a sequence of many-to-one relationships in an object model for the data sources. For each distinct set R, the process forms a data field set S, consisting of each dimension in R and each measure m for which R(m)=R. For each set S and for each measure in the set S, the process aggregates values of the measure according to the dimensions in S. The process builds a data visualization according to the data fields in the set S and the visual variables they are associated with.

Abstract: A method displays a chart and a visual analytic object superimposed on the chart. The chart displays visual marks representing a data set, displayed according to contents of displayed shelf regions, which determine characteristics of the chart. The analytic object corresponds to an analytic operation applied to the data set. The method detects a first input on the analytic object, and displays a moveable icon corresponding to the analytic object while maintaining display of the analytic object. The method also detects a second input on the moveable icon, and moves the moveable icon over a first shelf region. Upon ceasing to detect the input, the method updates the content of the first shelf region based on the analytic operation, and updates the chart according to updated content of the first shelf region.

Abstract: A method generates a graphical representation of a data source using a graphical user interface. The user interface includes a schema information region and a data visualization region. The schema information region includes field names associated with data fields. The data visualization region includes shelf regions that determine characteristics of a visual graphic. Each shelf region is configured to receive user placement of field names. The user selects field names and places each field name in a respective shelf region. The user edits a first shelf region, creating a first calculated element in the first shelf region. The first calculated element does not match any of the field names in the schema information region. The method generates a visual graphic based on the content of the shelf regions, including the user-selected field names and the first calculated element, and displays the visual graphic in the data visualization region.

Abstract: A method displays a first data visualization according to user placement of data fields in shelves of a user interface. Each shelf specifies a property of the data visualization and the data visualization includes visual data marks corresponding to data values for data fields in a dataset. A user selects a subset of the visual data marks. A popup summary is displayed that includes data value distributions for several data fields. In the popup summary, a second user input is detected corresponding to a first data field whose data value distribution is displayed in the popup summary. In response, the method displays a moveable icon corresponding to the first data field. The method detects a third user input to place the interactive moveable icon in a shelf in the user interface. In response, a second data visualization is displayed according to placement of data fields, including the first data field.

Abstract: A real-time visual feedback ensemble classifier generator and method for interactively generating an optimal ensemble classifier using a user interface. Embodiments of the real-time visual feedback ensemble classifier generator and method use a weight adjustment operation and a partitioning operation in the interactive generation process. In addition, the generator and method include a user interface that provides real-time visual feedback to a user so that the user can see how the weight adjustment and partitioning operation affect the overall accuracy of the ensemble classifier. Using the user interface and the interactive controls available on the user interface, a user can iteratively use one or both of the weigh adjustment operation and partitioning operation to generate an optimized ensemble classifier.
