摘要： A method for effective placement of data for visualization of multidimensional data sets using multiple pixel bar charts. Data is received comprising a plurality of records, each record having a plurality of attributes. From the plurality of attributes, a set of attributes is determined for placement of the plurality of records in a graphically displayable array comprising a plurality of data points, each data point representing one record of the plurality of records. In one embodiment, the graphically displayable array is a pixel bar chart. The plurality of records are arranged to construct the pixel bar chart for presenting the data in a format for detecting relationships between the plurality of records. The present invention provides a pixel visualization technique having a method of optimal data placement to resolve the locality and ordering constraints.

摘要： An visualization technique to unclutter the display and ease navigation in a large highly connected hyperbolic space. The visualization technique can be implemented by using an invisible link processor to execute an invisible link program. Initially, the invisible link processor only shows or displays the primary links (e.g., the parent-child path) of each node. All other non-primary links (e.g., secondary links or non-tree links) are invisible (i.e., not displayed for the user). Then, upon user selection the invisible link processor automatically maps the secondary child and sub-nodes associated therewith to the current selected node. The invisible link processor automatically restores (i.e., returns the previously moved secondary child and related sub-nodes to the original location in the hyperbolic space) upon receipt of a reset command. The visualization technique employs a link table, a link history log, and placeholders to check relationships among nodes including cyclic conditions. The visualization technique allows a user to freely focus on the hierarchy of interest without being disrupted by extra cross lines and intersections.

摘要： An event occurring in a particular geographic region is identified based on disseminated information containing public commentary in the particular geographic region. Attributes that are related to the event are identified, and sentiment words relating to the identified event are extracted from the disseminated information, where the extracted sentiment words are in a local language of the particular geographic region. A sentiment trend visualization is generated that depicts a trend of sentiments of at least a particular one of the identified attributes, wherein the sentiments are based on the sentiment words for at least the particular attribute.

摘要： A method executed by a system having a processor includes arranging pixels representing attributes into a plurality of rings. Each ring contains pixels representing a time series of attribute values for a respective one of the attributes. The method further includes providing a peak detection ring. The peak detection ring includes visual indicators for indicating a location of at least one peak in an attribute in the plurality of rings.

摘要： Data records representing user feedback are received, where the data records are associated with geometric coordinates. Pixels representing the corresponding data records are placed in positions in a graphical visualization according to the geometric coordinates of the data records, where the positions correspond to geographic locations. A subset of the pixels sharing a particular set of geometric coordinates is placed in a subregion of nearby positions in the graphical representation, where the pixels in the subset are placed in an order in the subregion according to values of an attribute of the data records corresponding to the pixels in the subset.

摘要： A scatter plot that represents plural periodic time intervals is animated as new data points are received, where the animating includes performing real-time backward rewriting. The real-time backward rewriting includes overlaying a subset of previously written data points with the new data points, and painting a remainder of previously written data points outside the subset in the scatter plot, where painting the remainder of previously written data points is performed without shifting pixels corresponding to the remainder. A divider structure is drawn in the scatter plot to indicate a position in the scatter plot between a current time point and a previous time point.

摘要： Data records contain corresponding values of an attribute and are associated with location information. Hierarchical levels of transparency images are generated, where each of the transparency images includes corresponding pixels that represent the respective data records, and where the transparency images at different ones of the hierarchical levels correspond to different zoom levels of a geographic map. At least one of the transparency images at a dynamically-selected one of the hierarchical levels is overlaid over the geographic map according to which of the zoom levels is selected by a user in zooming of the geographic map, where the at least one transparency image is automatically selected without user input.
