Parallel Coordinates Plot

The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub.
In the node configuration, you can choose the size of a sample you want to display and enable certain controls, which are then available in the view. This includes the ability to choose different columns or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the parallel coordinates plot in the desired shape quickly.
Since missing values as well as NaN (not a number) or infinite values cannot be displayed in the view, they will be omitted.

Interactivity between multiple views is currently only possible for views coming from the KNIME Views extension.

Options

Vertical dimensions

Defines the columns that are used as vertical dimensions in the plot.

Color dimension

Defines the column used to color the data by. Only columns which have a color scheme associated can be selected. You might need to use a Color Manager node before this node to add color schemes to specific columns.

Max rows

Numerical value that restricts the number of rows used for this visualization.

Title

The title of the graph shown above the generated image. If left blank, no title will be shown.

Value axis limits

Choose if the axis range of the value axis should be calculated automatically by the charting framework or the domain range should be used. You might need to use a Domain Calculator or Edit Numeric Domain node before this node.

Line shape

Choose whether the lines should be drawn straight or curved

Line thickness

Numeric value that defines the line size.

Enable image download

When checked, an image of the chart can be downloaded by clicking the image download button in the view.

Show tooltip

When checked, hovering over a line will show information about the data.

Selection

“Show” makes this view receive notifications about changes of the selection. “Edit” also allows you to change the selection and propagate any changes you make here to other views that show the selection.

Enable animation

When checked, the animation of the graph is active.

Generate image

If checked, adds an image output port and, upon execution, generates a PNG image which is made available via this port.

Width

The width of the generated image (in pixels).

Height

The height of the generated image (in pixels).

Views
