This is reflected in the width of your pie slice.
These are the total hours of all the work where you are listed as the Primary Assignee minus any work done by other team members on that same work.
For example, I have two tasks assigned to me for a total of 10 hours. However, Brian did two hours of that work helping me out (thanks, Brian!). Before Brian logged time, the chart would show I had 10 hours of assigned work. After Brian logs his time, my assigned time would drop to 8 hours (and his hours would go up by the same).
This is reflected in how complete your pie slice is.
These are the total hours you have logged. This includes any work on work that is assigned to you as well as assigned to anyone else.
This is reflected in how empty your pie slice is.
This is the work that is unfinished that you are responsible for. This could mean doing the work and logging the spent time yourself or working with a team member to get the job done! If you share the load, be sure everyone logs their time appropriately!
The basic date range depends on if you are viewing a sprint or project report.
If there are completed hours spent outside of the basic date range, then the date range will increase to include these dates.
At a minumim, the date range will over from the sprint start date to the end date.
At a minumim, the date range will over from the earliest sprint start date to the latest sprint end date.
Where does it start?
This line starts with the total amount of all estimated work.
As estimated hours are adjusted, the starting point will move up and down accordingly.
How does it move?
As the line progresses it moves down an equal amount each day until it reaches zero on the end of the date range.
Note: This means that zero hours are idealy spent during the first day. This is to account for a few things:

This line starts with the total amount of all estimated work.
As estimated hours are adjusted, the starting point will move up and down accordingly.
How does it move?
The completed hours for each day reduce the remaining effort line by the same amount.
Any completed hours that are completed prior to the offical start date will be added to the start of the remaining effort line.
Any completed hours that are completed after the offical end date will be added to the end of the remaining effort line.
These bars hours that are completed each day.
The first part of the bar shows the total hours of all work that hasn't been started yet. Unstarted work is work that hasn't had any spent hours yet.
The second part of the bar shows the total hours remaining on work that has previously been started. This is the "remaining time" of work that has had hours spent on it already.
The final part of the bar shows the total hours that all team members have spent across all work.
