Scatter Plot

Creates a scatterplot of two selectable attributes. Then each datapoint is displayed as a dot at its corresponding place, dependent on it's values of the selected attributes. The dots are displayed in the color defined by the Color Manager, the size defined by the Size Manager, and the shape defined by the Shape Manager.

Only columns with a valid domain are available in this view. Make sure that the predecessor node is executed or set the domain with the DomainCalculator node!

HiLiting:

The data points may be selected by either dragging a rectangle with the mouse over the points or by clicking on points. Hold control pressed for multiple selection. The selected datapoints may be hilited by either right-click to get the context menu or via the hilite menu in the menu bar.

Tooltip

Move the mouse over the data points to get detailed information about the data point (Row ID, and the x and y value).

Enter the maximum number of distinct nominal values that the view should consider. Columns with more values than the specified number will be ignored and can't be selected in the view. Please also note that nominal values must be present in the table specification of the input table (check it by inspecting the table spec tab of the predecessor's outport view). If no nominal values are present in the table, execute the predecessor or consider to use the "Domain Calculator" node and to enforce the determination of the nominal values.
