*3.5.2 LabVIEW and OriginPro*

National Instruments engineers have created various NI LabVIEW add-ons which contain many functions and subVIs to meet the required functionality.

Besides the add-ons developed by NI engineers, add-ons have been developed for some other applications such as Origin. Origin or OriginPro is a powerful data analysis and graphics software preferred by scientists and engineers in industry, academia and research laboratories around the world [4]. Once the data collected by LabVIEW, the end-user will need to analyze the data and generate reports for presentation. Origin provides powerful analysis and graphing tools to reanalyze and present data. The ability to communicate easily between LabVIEW and Origin is a good platform that can greatly increase its efficiency in terms of data analysis and presentation [5]. There are studies in the literature using Origin and LabVIEW for

this purpose [6]. Origin provides subVIs to make work in LabVIEW environment. These subVIs allow to data transfer from LabVIEW to Origin and the data to be analyzed and presented in the Origin environment. This subVIs can be accessed from the folder where OriginPro is installed (Samples\COM Server and Client \LabVIEW). Also, in order to quickly access these subVIs in the LabVIEW environment, the subVIs can be copied from the installed folder and then pasted into a folder named OriginPro in vi.lip\addons folder where LabVIEW is located [7]. OriginPro library can be accessed from the menu opened by right-clicking on add-

After adding the subVIs provided by OriginPro to LabVIEW, you can see subVIs
