DAQmxCreateLinScale

int32 DAQmxCreateLinScale (const char name[], float64 slope, float64 yIntercept, int32 preScaledUnits, const char scaledUnits[]);

Purpose

Creates and configures a scale that uses the equation y=mx+b, where x is the prescaled value and y is the scaled value. The equation is identical for input and output. If your equation is in the form x=my+b, you must first solve for y in terms of x.

Parameters

Input

Name

Type

Description

name

const char []

Identifies the custom scale for later use, such as when you create channels.

slope

float64

The slope, m, in the equation.

yIntercept

float64

The y-intercept, b, in the equation.

preScaledUnits

int32

The units of the values to scale.
