Tiller has two types of charts:
- A day chart, which displays the time tracked for a specific day in the form of blocks of time on a 24-hour scale. This chart can be used to edit time by dragging and resizing time, and also to create time by clicking and dragging. Hovering over a time block displays a tooltip which can be used to edit information about that time block, including editing start time, end time, changing the timer, and adding a note.
- A date-range chart, which displays the time tracked for each day within the range as a stacked bar chart. Clicking on any specific day on this chart will navigate to the day chart for that given day.
