Right now, when you try to analyze a roast, the RoastTime app does not allow to see all of the data on the screen at the same time. You need to scroll down to see X-axis with the time markers and Bullett settings, but when you do that you can no longer see the ROR, Bean Temp, Drum Temp, and Exit Temp readings that appear in colored boxes at the top of the screen. The first picture below is a screenshot of the app in fullscreen mode, without scrolling down - your can see ROR, Bean Temp, Drum Temp, and Exit Temp readings near the top. But, as shown in the second screenshot below, if you scroll down to see what time these readings occurred at, and the power, drum speed, and fan speed settings at that time, you can no longer see the ROR, Bean Temp, Drum Temp, and Exit Temp readings:
You should be able to see all the data at once.
Just my $0.02.
