Graph time range that you give to pets
From the question time range that students give to pets. By them can choose more than one choice. It found that most of the students have time range to give their pet is 6-7 am and 8-9 pm. That is, in the morning before leaving home and night after returning home. You can be seen that is a much aloof period. That means their pet will have to miss them so mush. For example my dog, if I leave home just 1-2 hours. When I came back home, it will make a gesture, glad and run up to me immediately
