I don't have any sketches, but there are a few apps with some characteristics that look good. Particularly:
1. Moods Tracker (Dannitt Pty Ltd) re- graph.
2. How was your mood today (DevJockeys)
3. DBSA wellness tracker
The important think to remember in my app is that it needs to be densely sampled, as per my initial draft; (1.1, 1.2, etc.; 5 is their normal) and that the subject should be able to 'draw' his/her day.
