This package contains all data and visualization models which are used in the different histogram implementations.

A histogram consists of one or more {@link org.knime.base.node.viz.histogram.datamodel.BinDataModel} which are drawn next to each other at their corresponding x value on the x axis. The value of a row for the selected x column defines to which bin a row belongs.

Each bin contains one or more {@link org.knime.base.node.viz.histogram.datamodel.BarDataModel}. A bar represents a selected aggregation column. The height of the bar is the aggregated value (count, sum, avg) of all values for the selected aggregation column.

A bar contains one or more {@link org.knime.base.node.viz.histogram.datamodel.BarElementDataModel}. The BarElements reflect the color of the row which is defined by the user in the Color Manager node.
