KNIME Base Nodes version 4.2.3.v202011031328 by KNIME AG, Zurich, Switzerland
During the 1980’s and early 90’s, Inselberg and Dimsdale (A. Inselberg and B. Dimsdale, "Parallel Coordinates: A Tool for Visualizing Multidimensional Geometry," Proc. IEEE Figure 11. Before and after a focus and context effect is introduced. Visualization 1990, IEEE Computer Society Press, San Francisco, California, USA, October 23-25, 1990, pp. 361-378.) introduced Parallel Coordinates, a representation of multi-dimensional information or data, in which multiple dimensions are allocated one-to-one to an equal number of 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.
Only columns with a valid domain are available in this view. Make sure that the predecessor node is executed or set the domain with the DomainCalculator node!
The data points may be selected by either dragging a rectangle with the mouse over the points on the parallel axes or by clicking on points or connecting line segments (if curves are drawn, selection works only on the datapoints). Hold control pressed for multiple selections. The selected datapoints may be hilited by either right-click to get the context menu or via the hilite menu in the menu bar.
Move the mouse over the data points on the parallel axis to get information about the row ID and the value.
Column Selection: Choose the columns you want to have displayed as parallel axes.
