ABSTRACT:
A graphical production system produces pixel bar charts, in various embodiments. In an embodiment, a pixel bar chart is constructed that may include multiple bars with substantially equal widths and potentially variable heights to enable visual data analysis. A bar may include a number of pixel units corresponding to a volume of data records represented within the bar. Selected visual indicators are displayed within the pixel units of the bar, where a selected visual indicator represents a value of an attribute of a data record represented by the pixel unit. In an embodiment, the pixel units may be ordered within a bar in a particular sequence (e.g., ascending, descending or some other order). Further, in an embodiment, the bar width is determined to minimize the amount of padding. In an embodiment, a visual indicator scale is displayed to indicate values associated with each visual indicator.
