The Scatter 3D is used for viewing three vectors at a time. It is fully rotatable and compared to the 2D scatter plot, it offers greater flexibility in finding similarities between plotted objects. The plot can be rotated by moving the mouse while holding down the middle mouse button. It can also be rotated using the "Rotate 3D" button in the plot toolbar.

Scatter 3D settings:

Data range: Specifies which vectors that are plotted against each other on X, Y and Z.

Color: Changes the coloring of the scatter 3D objects. Available options are [FIXED]; the same color is used for all objects, [INDEX]; the indices for the plotted vectors are used for the coloring, [VALUE]; the values of the selected vectors are used for the coloring, [CATEGORY]; Depending on the type of plotted vectors, either an observation category or a variable category is used for the coloring, [DENSITY]; the coloring is based on the the density of the plotted objects, i.e. how tightly they are grouped together.

Size: Changes the size of the plotted objects. Available options are [FIXED]; the same color is used for all objects, [INDEX]; the indices of the plotted vectors are used for the sizing, [VALUE]; the values of the selected vector is used for the sizing, [PERSPECTIVE]; the objects are sized according to the distance from the viewer. The farther away the object is, the smaller the size will be. This is the default setting for the Scatter 3D plot, [CATEGORY]; the size is changed according to the category.

Shape: Changes the shapes of the plotted objects. Available options are [FIXED]; all objects have the same shape, [CATEGORY]; the shapes of the objects are changed according to which category they belong to.

Label: Changes the labeling of the plotted objects. Available options are [NONE]; no labels are used, [INDEX]; the indices of the selected vector are used as labels, [IDENTIFIER]; An identifiers of the plotted objects is used as labels, [VALUE]; the values of the selected vector are used as labels, [CATEGORY]; depending on the type of plotted vectors, either an observation category or a variable category is used for the labeling.

Lines: Draws lines between the objects in the Scatter 3D Density plot. Available options are [NONE]; no lines are drawn, [INDEX]; the order of the drawn lines is based on the indices of the plotted objects, [VALUE]; the order of the drawn lines is based on the values of the selected vector.

Comment: Options available are [NONE], [CUSTOM] and [CATEGORY]. With [CUSTOM] the user can enter a custom comment using the advanced settings. The custom comment will be shown in the tooltip box that appears when the mouse pointer hovers above a data point. The comment is also shown in any text box created from the table toolbar. When [CATEGORY] is selected then the comment will contain either an observation category or a variable category depending on the type of plotted vectors.
