Rendering data visualization with minimal round-off error

摘要

Systems and methods in accordance with various embodiments of the present invention provide for the rendering of data visualizations with minimal round-off errors. The data visualization method represents a dataset as graphical elements within a graphical layout area by performing layout of a data value within the dataset on the graphical layout area. The data value is positioned on the graphical layout area by determining a floating point position of the data value. A round-off error is calculated by casting the floating point position to an integer position on the graphical layout area. The round-off error is distributed to one or more subsequent data values that are yet to be positioned on the graphical layout area.
