Abstract: A method at an electronic device with a touch-sensitive surface and a display includes displaying a first chart on the display. The first chart concurrently displays a first set of categories and each respective category has a corresponding visual mark displayed in the first chart. The method further includes detecting a first touch input at a location on the touch-sensitive surface that corresponds to a location on the display of a first visual mark for a first category in the first chart, and, in response to detecting the first touch input, removing the first category and the first visual mark from the first chart via an animated transition, and updating display of the first chart. The first visual mark moves in concert with movement of a finger contact in the first touch input during at least a portion of the animated transition.

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 is performed at an electronic device. The process displays a line chart, which includes a first plurality of data marks and a first plurality of line segments connecting adjacent data marks. The process detects a touch input, and expands the line chart horizontally, including expanding a first line segment. The process adds a second plurality of data marks on the first line segment, thereby subdividing the first line segment into a second plurality of line segments, which are initially collinear. After expanding the chart and adding the second plurality of marks, the process determines an ordinate value for each of the second plurality of marks, and animatedly moves each of the second plurality of marks from the first line segment to a respective vertical location defined by the respective determined ordinate value. The process concurrently moves each of the second plurality of line segments according to its endpoints.

Abstract: A user selects a dataset and a first interaction profile. There are multiple interaction profiles, each specifying a corresponding user interface and a corresponding decision tree for forming data visualizations according to user-selected data fields. A first data visualization user interface is displayed corresponding to the first interaction profile. Using the first data visualization user interface, the user selects data fields from the dataset and uses them to specify data visualization characteristics. The method displays a first data visualization according to the user-selected data fields and the decision tree for the first interaction profile. When the user selects a second interaction profile, the method displays a second data visualization according to the second interaction profile. The second data visualization uses at least some of the user-selected data fields.

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 user selects a dataset and a first interaction profile. The first interaction profile is one of: category world, time world, or geography world. The first interaction profile corresponds to a first data visualization user interface. Without further user interaction, a method selects multiple fields in the dataset according to the first interaction profile and displays a first data visualization according to the first interaction profile. The first data visualization includes visual marks based on the selected fields. The user specifies some data visualization characteristics, and the method updates the first data visualization according to these characteristics. The user selects a second interaction profile.

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.
