Description
Class Summary | |
---|---|
LineInfo | Represents a line (one row) in the parallel coordinates plot. |
NominalParallelAxis | Represents a ParallelAxis
with nominal values and provides access to the possible values. |
NumericParallelAxis | Represents a ParallelAxis
with numeric values and provides access to the minimum and maximum value of
the domain. |
ParallelAxis | Represents a parallel axis in a parallel coordinates plot with an x position,
a height, a Coordinate , a name and a
flag, whether this ParallelAxis is selected. |
ParallelCoordinateDrawingPane | Since the
ParallelCoordinatesPlotter
only calculates the mapped datapoints, the connection of them by lines or
curves is done here, also the missing values handling. |
ParallelCoordinateNodeFactory | |
ParallelCoordinateNodeView | Extends the
DefaultVisualizationNodeView
since it provides an additional menu to show, fade or hide unhilited lines
(rows). |
ParallelCoordinatePlotterProperties | In addition to the
MultiColumnPlotterProperties
a tab to select how to handle missing values and a tab to adjust dot size,
line thickness and select whether to show or hide dots is provided. |
ParallelCoordinatesPlotter |
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:
