Band

Category

Realization

Function

Divides a specified field into bands.

Syntax


band = Band(data, value, number, remap);

Inputs
Name Type Default Description
data scalar field none field to be divided
value scalar or scalar list data mean band divisions
number integer no default number of divisions
remap string "low" data values applied to bands

Outputs
Name Type Description
band field or group divided input

Functional Details

The values used for dividing a field into bands are specified by value or number.

data

is the field to be divided and must have 2-dimensional connections (triangles or quads).

value

specifies the value(s) at which the divisions are to be created (i.e., the data values in the data field). If this parameter and number (see below) are both unspecified, the module, by default, constructs the division at the arithmetic mean of the data set.

number

specifies the number of equal divisions to be created between the minimum (min) and maximum (max) data values of the field. The first division is created at min + delta, the second at min + 2 * delta, and the last at max - delta, where delta = (max-min)/(number+1).

Note: This parameter is ignored if value is specified.

remap

assigns data values to the elements in each band:

"low"

specifies that all connection elements are assigned the value of the lower boundary of the band (the lowest data value if it is the first band).

"high"

specifies that all connection elements are assigned the value of the upper boundary of the band (the largest data value if it is the last band).

"original"

specifies that the data values remain unchanged.

Components

This module creates new "positions" and "connections" components, and adds a "colors" component if one is not already present. The "data" component is modified according to the value of remap. The output data are connection dependent.
