To view the hour burndown chart for your project version,
Log into JIRA.
Click the 'Agile' link's down-arrow in the top navigation bar and select 'Chart Board' from the resulting dropdown menu. The 'Chart Board' will be displayed.
Select your project from the project dropdown (top left of the chart board above the 'Chart Board' dropdown), if it is not already selected. The 'Chart Board' will refresh with information for your project.
Using the Chart Board Navigation Bar, select the version whose chart you wish to view in the Version dropdown, then select 'Hour Burndown Chart' from the dropdown menu next to it. The hour burndown chart for the version will be displayed (see screenshot below).
The 'View Version' dropdown only includes versions which contain issues that belong to at least one unreleased Fix Version (and belong to a project that is GreenHopper-enabled).
You can toggle items in the chart on and off, by selecting or clearing their check boxes in the legend under the chart.
You can also print the chart by clicking the version's Actions menu in the Statistics Column and selecting 'Print Chart' from its dropdown. Please refer to the Chart Board - Statistics Column section for details.
The hour burndown chart provides you with the following information:
Remaining Values - Ongoing (dotted line) — The number of remaining hours burned since midnight on the current day. The gradient of this curve may change throughout this day.
Remaining Values - Trend (dashed line) — The projection of remaining hours to be burned until the version release date, based on the actual hourly burn data from the start of the project.
Guideline (solid line) — The ideal burndown. This is computed with the remaining estimates, not the original estimates of the hours remaining at the version's start date. Hence, this calculation makes the guideline slope more accurate and precise.
Team effort - Ongoing (dotted line) — The total time worked by the team since midnight on the current day. The gradient of this curve may change throughout this day.
Estimate accuracy (solid line) — The sum of the Team Effort and the Remaining Values (that is, number of hours remaining). If you have estimated your issues accurately, this line will be flat. If you are underestimating your issues, this line will trend upwards. If you are overestimating your issues, this line will trend downwards.
Estimate accuracy - Ongoing (dotted line) — The sum of the Team Effort and the Burndown, since midnight on the current day. The gradient of this curve may change throughout this day, although if you have estimated your issues accurately, this line will follow a flat trend.
Required daily burndown rate (solid line) — The daily hour burn rate required to attain your goal. The is the Burndown divided by the number of days remaining until the end date.
Required daily burndown rate - Ongoing (dotted line) — The daily hour burn rate required to attain your goal, since midnight on the current day. The gradient of this curve may change throughout this day.
Tip: If you set up a version to be the parent version of a number of child versions, you will be able to view the burndowns of the parent and child version merged into one. This can be useful for providing a visual overview of a release with multiple iterations.
