Scatter Plot (legacy)

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 (RowID, and the x and y value).

Properties:

Default Settings:

• Mouse Mode: choose "Selection" to select the datapoints or "Zooming" to zoom in. If you have zoomed in you may choose "Moving" to navigate in the zoomed display.
• "Fit to screen" fits the display again to the available space.
• "Background color lets you choose the background color of the display.
• "Anti-aliasing": Check if the view should enable anti-aliasing (make a smoother drawing). This will slow down performance as well.

Column Selection: Choose the columns you want to have displayed as x and y coordinate. With the "X attribute" and "Y attribute" spinners the range of the axes can be adjusted. The left spinner changes the lower end, the right spinner the upper end.

Appearance:

• "Dot Size" lets you define the size of the dots.
• "Jitter": if a nominal column is selected you may adjust how much the values are jittered (scattered around there origin).
