So, I am using time-aware charts to present progress for an ongoing project. The progress is measured by weeks. This means that the customer needs to see intuitive information in the graph and in the tooltip. They allso need to see the latest numbers.
The way time-aware charts work, this seems to be a bit buggy, or I am missing something crucial.
First; The tooltip for any given week shows the first day of the week. This makes it difficult to know if the numbers represent the current week, or the past week (it is the past week). But, still, the graph shows weeknumber of the current week, hence the confusion.
Second; Since this is a time-aware chart, it makes sense to show the last point in the chain
This can be critical in a time-aware chart since the last point is often the current date, or atleast the most recent date and, therefore, most interesting.
