Weight Graph shows your weight on a trend graph. Click the Edit button to enter a weight value, perhaps once a day or at your leisure. With that recording over time you can make informed decisions based on documented results. The data entry and viewing is intended to be so effortless that a long term trend is easy to accomplish. Touch-hold the trend graph to send it to others. If you need more features (which results in additional complexity) then try the Expert setting. The Expert setting may be appropriate for clinical settings where multiple people are involved or you may want to use the Expert settings just because it is there. Either way, Easy or Expert, there are options to help you make informed decisions.
