How to read and understand Burndown chart for children cards

The vertical Y-axis is the number or size (depending on the selected display) of tasks in work.

The horizontal X-axis shows days. 

The default countdown starts from the date the card was first moved to the column with the type "In progress" or the creation date. You can change the countdown date in the chart settings.

Cards added before this date are the main work, cards added after this date are the added work.

The trends in this chart allow you to predict the completion date of a task. 

The intersection of the blue line with the grey horizontal line (time axis) shows the predicted completion date with no tasks added. 

In the chart above: if no tasks are added from the current date 20.10, the predicted completion date is 25.10. 

If tasks are added at the same pace as from the task start date (dark bars) the predicted finish date will shift to 30.10 (intersection of the dark line with the blue one).

If tasks are added faster than current tasks are completed - the trend of the added work will diverge from the trend of the completed work, and you will only get the forecast completion date without new tasks added. The graph below illustrates this example.

Only children that do not have their own child cards are included in the chart. In the picture below, card "b" will not be included, since it has its own child cards.

Please note that deleted cards and child cards of deleted tasks do not appear in the chart.
