COMBINING PARALLEL COORDINATES AND HISTOGRAMS
A system provides data visualization with the capability of combining parallel coordinates and histograms. Parallel coordinates typically display lines between two or more vertical lines representing a coordinate element. In addition to displaying lines between coordinate element axes, histograms are provided at each element line to indicate the instances of data associated with line values. To create parallel coordinates with histograms, bin values may be determined for the parallel coordinates. Data is then accessed, and a particular bin value is incremented for each data point that falls within the bin. The parallel coordinates are then displayed with the histograms indicating a quantity of data associated with each coordinate value.
1 . A method for displaying data, comprising:
providing an image of parallel coordinates corresponding to a set of multi-dimensional data through an interface provided on a display; and
providing a plurality of histograms on each parallel coordinate, the histograms determined from the set of multi-dimensional data.
2 . The method of claim 1 , further comprising determining a data range for a histogram data bin.
3 . The method of claim 1 , further comprising aggregating the data bins from the set of multi-dimensional data.
4 . The method of claim 1 , wherein the histograms include graphical information and numerical information.
