I used a mood chart for awhile, but I always struggled to label my mood on a numerical scale. I found that I often went back and made changes to previous days as I realized my symptoms had been more or less severe than I thought when compared to the current day. That made me a little nuts. Also, I often don’t realize how depressed I am or if I’m manic or hypomanic so there were inaccuracies. It was still interesting to see things plotted on a graph.
