Package org.knime.base.node.viz.plotter.parcoord Description

A ParallelCoordinatePlot is a representation of multi-dimensional information or data, in which multiple dimensions are allocated to parallel axes on-screen. An object in a data set is then mapped as a series of points, one per axis, with the position of each point on the axis being dependent on their value in the associated dimension. The points are then joined together by line segments from one axis to its immediate neighbour, forming a poly-line across the set of axes.

The ParallelCoordinatesPlotter creates the parallel coordinates, represented by either a NominalParallelAxis or a NumericParallelAxis and determines their x position. Then the data points of the data to visualize are mapped to these coordinates. This results in a The LineInfo for each row, which is passed to the ParallelCoordinateDrawingPane. The ParallelCoordinateNodeView is necessary, since an additional menu is provided to show or hide the unhilited lines. The ParallelCoordinatePlotterProperties let the user selected the columns of interest, adjust the line thickness and dot size and whether the dots are shown or hidden. In addition, the way how missing values are handled can be selected:
