Class Summary
AbstractHistogramVizModel	This is the basic visualization model for a histogram.
BarDataModel	This class represents one bar in the histogram.
BarElementDataModel	This class represents the smallest element of a histogram and corresponds to the color in which the rows of this element are colored.
BinDataModel	This class represents one bin in the histogram.
BinDataModelComparator	Used to sort the bins in their natural order by their caption or boundaries.
FixedHistogramDataModel	This is the fixed data model implementation of the histogram which is created only once when the user executes a node.
FixedHistogramVizModel	This class holds all visualization data of a histogram.
HSBColorComparator	Comparator comparing two `Color` objects using the HSB color space.
InteractiveBarDataModel	This class extends the `BarDataModel` to support hiliting.
InteractiveBarElementDataModel	This class extends the `BarElementDataModel` to support hiliting.
InteractiveBinDataModel	This class extends the `BinDataModel` to support hiliting.
InteractiveHistogramDataModel	This data model holds all information (DataRows, DataTableSpec) to provide the flexibility.
InteractiveHistogramVizModel	Extends the `AbstractHistogramVizModel` to allow hiliting and column changing.

Class Summary

AbstractHistogramVizModel

This is the basic visualization model for a histogram.

BarDataModel

This class represents one bar in the histogram.

BarElementDataModel

This class represents the smallest element of a histogram and corresponds to the color in which the rows of this element are colored.

BinDataModel

This class represents one bin in the histogram.

BinDataModelComparator

Used to sort the bins in their natural order by their caption or boundaries.

FixedHistogramDataModel

This is the fixed data model implementation of the histogram which is created only once when the user executes a node.

FixedHistogramVizModel

This class holds all visualization data of a histogram.

HSBColorComparator

Comparator comparing two Color objects using the HSB color space.

InteractiveBarDataModel

This class extends the BarDataModel to support hiliting.

InteractiveBarElementDataModel

This class extends the BarElementDataModel to support hiliting.

InteractiveBinDataModel

This class extends the BinDataModel to support hiliting.

InteractiveHistogramDataModel

This data model holds all information (DataRows, DataTableSpec) to provide the flexibility.

InteractiveHistogramVizModel

Extends the AbstractHistogramVizModel to allow hiliting and column changing.

Package org.knime.base.node.viz.histogram.datamodel Description

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

A histogram consists of one or more 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 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 BarElementDataModel. The BarElements reflect the color of the row which is defined by the user in the Color Manager node.
