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

A scatter plot maps to columns (dimensions) of data to 2-dimensional space, which results that each row (data instance) can be represented as one 2-dimensional point. The ScatterPlotter maps the data to visualize to the screen coordinates. Afterwards a data point is represented by a DotInfo. All DotInfos are stored in a DotInfoArray which is passed to the ScatterPlotterDrawingPane.

For nominal values a jittering is realized. Unhilited dots may be hidden or faded, which is the reason for extending the DefaultVisualizationNodeView with the ScatterPlotterNodeView which adds the show/hide menu to the menu bar.
