Scatter 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 for x and y or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the scatter 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

Horizontal dimension: Defines the column that contains the values for x coordinates.
Vertical dimension: Defines the column that contains the values for y coordinates.
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.
Axis limits: Choose if the axis range should be calculated by the charting framework, taken from the domain range or set manually. You might need to use a Domain Calculator or Edit Numeric Domain node before this node.
Horizontal min: Value that sets the horizontal axis minimum.
Horizontal max: Value that sets the horizontal axis maximum.
Vertical min: Value that sets the vertical axis minimum.
Vertical max: Value that sets the vertical axis maximum.
Horizontal axis label: The label for the X-Axis. If left blank, no label will be shown.
Horizontal axis scale: Choose if the X-Axis should be displayed in linear or logarithmic scale.
Vertical axis label: The label for the Y-Axis. If left blank, no label will be shown.
Vertical axis scale: Choose if the Y-Axis should be displayed in linear or logarithmic scale.
Point size: Numeric value that defines the point size for each data point.
