Sleep Tracker Help??

Hello! I've been sleeping at very irregular times and I've been trying to use the tracker... but I can't seem to register it correctly?

I am new to this... so I don't know how much anyone can help me.. but if you can look at my tracker, or look at my sleep times... and show me how to properly report my times, so my graph is accruate.

Tuesday:
4am to 11:30am
(I was up until 4 in the morning, which would technically be Tuesday Morning. I slept for 7.5 hours and woke up at 11:30am).

Wednesday
Went to bed at 1am. Woke up at 2pm. Went to bed at 10pm
( I was up from 1130am Tuesday until 1am on Wednesday, which is when I went to bed. I slept for 13 hours until 2pm on Wednesday. I was up from 2pm until 10pm Wednesday)

Thursday
Woke up at 2pm. Went to bed at 3pm. Woke up at 8pm.
(After falling asleep at 10pm on Wednesday, I slept until 2pm on Thursday. I went back to sleep at 3pm, slept for 5 hours, and woke up at 8pm.)

I have no trouble telling the chart that, let's say, I slept today from 3pm to 8pm. But I can't figure out how to... overlap my days? I'm usually good with charts and graphs... I don't know why I'm not getting this......
