Use Graphical Analysis to seamlessly collect, analyze, and share sensor data in science and math classrooms. Graphical Analysis facilitates student understanding with real-time graphs of experimental data. Students are able to enhance their lab reports by easily determining statistics, performing curve fits, and adding annotations.

Graphical Analysis, in combination with supported hardware, makes it possible to use your mobile device to collect data from a wide range of Vernier sensors, including temperature, motion, force, pH, and more. You can also collect data from your mobile device’s built in accelerometers or manually enter data into the data table for analysis. Data can be wirelessly streamed to each member of a lab group using the Data Share features of LabQuest 2 or a computer running Logger Pro.

Once data have been collected or entered into Graphical Analysis, students can analyze the data, export data and graphs to create a lab report, or send their finished work to the teacher. Graphs can be exported to Photos, Mail, or note-taking apps, or printed on a printer. A CSV file of the data can be shared with other users or opened in different software, such as a spreadsheet program, for additional analysis.

Key Features - Data Collection
• Collect and analyze data from a Go Direct sensor
• Use LabQuest Stream to collect data from up to five sensors simultaneously.
• Collect and analyze data from a Go Wireless sensor or Go Wireless Link and a compatible Vernier sensor.
• Stream data to multiple students from a single source via wireless Data Sharing with LabQuest 2 or Logger Pro.
• Collect acceleration data using your mobile device's built-in accelerometers.
• Collect time-based or event-based data.
• Manually enter data and analyze them using Graphical Analysis.

Key Features - Data Analysis
• Display one, two, or three graphs simultaneously.
• View data in a table.
• Edit and auto-save data, graphs, annotations, statistics, and curve fits.
• Draw predictions on a graph.
• Pinch to scale graphs.
• Examine and select data.
• Perform curve fits, including linear, quadratic, natural exponent, and more.
• Create text annotations and add graph titles.
• Export graphs and data.

It works well!


I used my IPhone 6s to download and install the software. The Bluetooth connection needed to via software, not phone Bluetooth connection. After did some modifications on x & y axis through graph options at lower left corner of software. It works well!! Very convenient for my gas law experiment.

Does not work!


Maybe it’s because of iOS 11, but I cannot connect to the LabQuest2 with an iPhone web browser OR this app.
Please fix! Thank you.

Developer Response

We are sorry you were unable to connect to your LabQuest 2 with Graphical Analysis 4.0.1. This issue should be fixed in Graphical Analysis 4.0.2.

No sine curve fit

Sad Physics student

Hey, here’s a bad idea, don’t include any of the trig functions in your curve fit selection :-(

Developer Response

Thanks for your suggestion. We plan to include a sine fit in a later release.
