DAQmx Create Scale (Polynomial) (G Dataflow)

Last Modified: September 18, 2017

Creates a custom scale that uses an nth order polynomial equation.

name

name identifies the custom scale for later use, such as with the DAQmx Create Virtual Channel node.

forward coeff

forward coeff is an array of coefficients for the polynomial that converts pre-scaled values to scaled values. Each element of the array corresponds to a term of the equation.

For example, if index three of the array is 9, the fourth term of the equation is 9x3.

reverse coeff

reverse coeff is an array of coefficients for the polynomial that converts scaled values to pre-scaled values. Each element of the array corresponds to a term of the equation.

For example, if index three of the array is 9, the fourth term of the equation is 9y3.

error in

error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.

datatype_icon

pre-scaled units

pre-scaled units is the units of the values to scale.

datatype_icon

scaled units

scaled units is the units to use for the scaled value. You can use an arbitrary string. LabVIEW uses the units to label a graph or chart.

datatype_icon

scale out

scale out is a reference to the custom scale this node creates.

datatype_icon

error out

error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.

Where This Node Can Run:

Desktop OS: Windows

FPGA: LabVIEW NXG does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
