What are point scales?
When estimating a story, you choose a value from the project’s point scale. Currently, Tracker supports three default point scales: Linear: 0/1/2/3, Powers of 2: 0/1/2/4/8, and Fibonacci: 0/1/2/3/5/8, or you can create your own custom point scale. To use your own set of point values for your project, go to your project settings, choose ‘Custom’ in the point scale dropdown and enter up to 12 numbers in ascending order, separated by commas. Points must be whole numbers in the range of 0 to 999. When using a custom point scale, the estimate values will appear as numbers, instead of the bars that you see when using one of the default point scales. Unestimated stories will show the first 5 point values, which you can click to select. If your point scale has more values, you can choose one of them to estimate a story by clicking the ‘+’ button on the right.
