The graph view on iLivestock iOS will display your recorded animal weights from birth weight to the most recent recording
Below is a video showing you how to navigate to the animal's weight data graph by viewing the animal summary, and pressing any of the animal's recorded weights under the 'Metrics' section. From here, a menu will appear for you to select 'Graph View'.
Below is a screen shot displaying the graph view while weighing the animal. Just double tap the weight value box to make the graph appear/hide.
Tip: The app remembers if you had the graph shown or hidden from the previous animal, so you don't need to open/close it for every animal!
