In late November of 2018, Vernier Video Physics for iOS was updated to make it possible to export data to our Graphical Analysis 4 app. Prior to this update, it was only possible to export Video Physics data to Logger Pro and our Graphical Analysis GW app. Graphical Analysis 4 features a file format (.ambl) that is transferable among all five platforms that run Graphical Analysis: Windows, Mac, Chromebook, Android, and iOS.
What changed: Instead of opening data in Graphical Analysis GW, open it in Graphical Analysis 4. We changed the menu options in order to accommodate changes in other software titles.
The complication arises because in 2018 we are transitioning between two titles with the Graphical Analysis name. The older application is now known as Graphical Analysis GW (GraphicalGW under the icon on your screen); it continues to exist largely to support the older Go Wireless sensors. The newer application, with the name Graphical Analysis (Graphical under the icon on your screen), is the one to use for all other purposes, including doing curve fits and such with Video Physics data.
You will need to have Graphical Analysis installed (it is free). Then, to export data to it from Video Physics, take these steps:
1. Launch Graphical Analysis
2. Switch to Video Physics
3. Select Graphical Analysis file from the Share menu.
4. Choose Open In…
5. choose Graphical Analysis from the list. (if Graphical Analysis isn’t showing in the list, turn it on using the More option)
Your Video Physics data will open in Graphical Analysis.
If the data don’t show up right away in Graphical Analysis, repeat the share steps. There’s a bug we’re working on in Graphical Analysis that prevents it from accepting data if the app isn’t already running (hence the first step is launching Graphical Analysis). We hope to have that resolved in a followup release of Graphical Analysis.
