Graph IDE3D Data Graphics ► Scatter

The 3D Scatter graphic represents a sequence of 3D points, examples of which are shown below.

Some standard operations are itemized below.

Data Editor

The Data Editor for the Point Map is shown below.

Table

Table controls are described in the Tables section.

The rows represent a 3D point while in atomic mode or x, y, z values in each respective cell while in component mode.

Graphics Editor

The Graphics Editor for the Point Map is shown below.

Common Controls

Controls common to all graphics are described in the Graphics section.

Color Map Attributes

The color map is further described in the Color Map section.

Graph : Shows a graph of the color map.

Function : Select this to set the color map function. Typically it is set to linear.

Start Color : Defines the start Color of the color map.

End Color : Defines the end Color of the color map.

Number : Defines the number of samples in the color map.

Grid Attributes

Grid attributes are controlled by the normal stroke controls defined in the Graphics section.

Fill Editor

The Fill Editor for the 3D Scatter graphic is shown below.

Fill attributes is a false color table of RGBA components, one for each point. These can be overridden by the Color Interpretation setting and that setting must be False Color Map in order for the elements of this table to take effect. Notice that this table is the same values presented in the Point Tags Colors editor.

Table

Table controls are described in the Tables section.

The rows represent a segment color values. While in Atomic mode, the cell represents a rgba value and while in component mode the cell represents either single r, g, b and a. Hence, in atomic mode there is one column while in component mode there are four columns.

Note that if the Data sequence is changed then the Fill sequence will not change.

Segments Editor

The Segments Editor for the 3D Scatter graphic is shown below.

Segments are the line segments interpolated between each 3D point. See Sequence Colors for additional information. A transparent color can be used to define an unconnected segment and then the data points can appear to be independent curves which represent separate data sets.

Table

Table controls are described in the Tables section.

The rows represent a segment color values. While in Atomic mode, the cell represents a rgba value and while in component mode the cell represents either single r, g, b and a. Hence, in atomic mode there is one column while in component mode there are four columns.

Note that if the Data sequence is changed then the Segments sequence will not be change.

Stats Editor

The Stats Editor for the Scatter graphic is shown below. Note that each X, Y and Z statistic is an orthographic statistic, i.e.: That value that is the statistic on the respective graph planes.

Basics

Number Of Points : Shows the number of points in the Scatter.

X-Minimum : x-minimum value of all the data points.

Y-Minimum : y-minimum value of all the data points.

Z-Minimum : z-minimum value of all the data points.

X-Maximum : x-maximum value of all the data points.

Y-Maximum : y-maximum value of all the data points.

Z-Maximum : z-maximum value of all the data points.

Basic Distribution

The basic distribution is shown separately for the x, y and z dimensions.

Mean : Shows the mean of the data.

Median : Shows the median of the data.

Standard Deviation : Shows the standard deviation of the data.

Range : Shows the range of the data (maximum - minimum).

Linear Regression Constants

Note that linear regression may also be referred to as line fit.

Slope : Shows the slope of the linear regression.

Y-Intercept : Shows the y-intercept of the linear regression.

Correlation : Shows the correlation constant of the linear regression.
