• Optional triggering of time-based data collection based on sensor value
• Customizable unit display on supported sensors
• Sensor calibrations
• Option to zero and reverse sensor readings
• Graph match feature for use with motion detectors
• Manual entry of data from keyboard and clipboard

Key Features - Data Analysis
• Display one, two, or three graphs simultaneously
• View data in a table or show a graph and table side-by-side
• Draw Predictions on a graph to uncover misconceptions
• Examine, interpolate/extrapolate, and select data
• Use Tangent tool to show instantaneous rates of change of the data
• Find area under a curve using the Integral tool
• Apply Statistics calculations to find mean, min, max, and standard deviation
• Perform curve fits, including linear, quadratic, natural exponent, and more
• Add calculated columns based on existing data to linearize data or investigate related concepts

Vernier ruined my life

Before downloading this app to use for my physics class I was happy. And safe. But now I’m depressed. This app has Bluetooth constantly enabled and won’t turn off even after downloading!!!!! I had to sell my phone but it was still to late and I developed stage 4 testicular cancer from my phone being in my pocket. It’s ok because when I die I will live on because it already stole my identity and sold it to China. This morning I was approached by a man who asked if I wanted to play a game for money to pay for my cancer treatment. He would pay me if I won but if I lost he got to slap me weird. Anyways he gave me a card with 3 shapes and a phone number to continue playing. I called and am about to get into the car picking me up. It appears the guy has a red jump suit on. I will update again later if this guy works for vernier to save me.

Why so many 1 Stars...?

I don’t understand why this app is so lowly rated works just like it should.
Update: Completing my second physics lab with this app now and I still enjoy it. So far it has deleted one of my graphs when I closed it but it’s only done this once. I can plot multiple columns from multiple data sets in one graph which is great but you can’t pick and chose which columns you want plotted from each data set. So if you want to plot velocity from data set 1, tension from data set 2 and log (tension * velocity) from data set 3 you can’t. You can however do this in the PC version of Graphical Analysis but again a good app just understandably missing some features.

Immediately received a series of inexplicable urinary tract infections

Got this app for my physics app and worked great. However, I noticed a sharp burning in the bathroom. Every graph I make, it gets more and more painful. My doctor prescribed me with antibiotics for the infections, but to no avail. I have had a catheter inserted for a month now and have to switch it out every evening. The pain is unbearable. My wife and children haven’t spoken to me in weeks. I think I will get my member removed in the coming days because I simply cannot take it anymore. It all started because of Vernier graphical analysis, and I hold the developers entirely responsible. Great graphing though.
