I don't know, these charts were quite intuitive for me. Of course these are not without faults. First one is obvious. Second one becomes quickly clear when you realize that it has to be total of hours over some period of time. Otherwise it would not make sense. Third one is quite interesting. It is very informative and interesting to observe. These charts could be made better naturally. Title and short description would definitely help. For the second one I would also include totals - for each day, for each time period and most importantly grand total that has to be the same for days and periods. Also small explanation that this is hours distribution over period of this and that. For the third one I would fix units of the duration. Current ones are difficult to interpret. Hours scale would make the most sense probably - 10, 20, ..., 40 (a normal work week, in the middle), ... 80. I do not think that there is nothing bad in having multiple interests. Distributing ones time between multiple interests is a difficult task to tackle but it does not make it automatically meaningless. It is actually a good idea to have some time management and good data always helps.
