Scatter Plot Matrix

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 for the scatter matrix plot or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the scatter plot matrix 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

Dimensions: Defines the columns that are used as 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 axes 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.
Point size: Numeric value that defines the line size.
Matrix layout: Show scatter plots in upper or lower triangular matrix
Display legend: When checked, the chart’s legend is displayed.
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.
Enable animation: When checked, the animation of the graph is active.
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.
Generate image: If checked, adds an image output port and, upon execution, generates an image which is made available via this port.
Image type (SVG, PNG): Choose between the superior quality provided by SVG vector graphics and the better performance of the PNG raster images. SVG graphics are sharp, also when zoomed, and text labels within the graphic can be searched for. On the other hand, PNG images can be smaller and render faster when there are many data points, for example, in a scatter plot.
Width: The width of the generated image (in pixels).
Height: The height of the generated image (in pixels).
