Summary:

This tool enables you to estimate the onset of slope change in a graph curve

Description:

** Origin version 7.5 SR5 is required **

Often one may want to quickly estimate a point in a graph curve where there is transition/onset point such as shown in the image below.

Typically users want to either pick two points on the curve and draw a tangent at each and find the point of intersection, or they want to pick four points and lines are drawn using each pair of points and the intersection is computed. This tool supports both methods.

To install download the Origin Pack File (OL_Estimate_Onset.OPK) and drag-and-drop the file onto Origin. A new toolbar called Onset will be added. The third button on this toolbar will bring up a PDF document with instructions on how to use this tool.
