Running the NI-ELVIS Scope Front Panels in LabVIEW 8.2 Primary Software: Driver Software>>NI ELVIS Driver VIsPrimary Software Version: 2.1 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I have installed NI-ELVIS 3.0, and when I try to run the Scope Front Panel source code VIs from inside of the LabVIEW development environment the graph does not seem to update correctly. The data inside the graph does not fill the entire display. This behavior does not occur if I run the ELVIS Scope Front Panel from the ELVIS application. Solution: The NI ELVIS VIs were written in LabVIEW 7.1, and when you run the NI-ELVIS application it launches and uses the LabVIEW 7.1 Run-time engine and everything works correctly. Using the Run-time engine you will see a display like the one below. In LabVIEW 8.2, there were changes made to the graph and if you run the NI-ELVIS source code VIs inside of the LabVIEW development environment you will get a display like the one below. To allow the NI-ELVIS source code VIs to operate correctly inside of LabVIEW 8.2, one simple change needs to be made to the ELVIS SCOPE - Two Ch Scope Update.vi typically found here: C:\Program Files\National Instruments\LabVIEW 8.2\instr.lib\NI ELVIS\NI ELVIS - Scope.llb\
This VI will have the section of code shown below. Simply change the circled property node to include the XScale.ScaleFit property as pictured below. Related Links: Attachments:  - new_graph.jpg - old_graph.jpg - Scope_VI_500.jpg - updated_property.jpg
