The Comments per reviews graph displays the number of interactions in code reviews. You can display this data by day, week, month, or by sprint, depending on your preference. However, note that if a Kanban-type board has been linked to your Axify project, the "sprint" option will not be available in the filters at the top of the page. In addition, the periods "last 6 months" and "last year" do not allow the display by day.
Reading the graph
For the following graph, the displayed period is the last three months, and the display mode is by week. On average, we can see that the code reviews merged per week have 0.9 comments. Although variations are inevitable, we see here good stability (according to the trend shown by the red dotted line).
In the case of this team, the variation indicator informs us that it is a decrease of 26% for the current period compared to the previous period. To learn more about the variation indicator and its calculation, check out this article!
Psst! While a high number of comments may seem beneficial, this is not necessarily the case. Sometimes adressing a topic verbally speeds up processing time and reduces the number of comments. Conversely, a low comment count may indicate a lack of interaction (or challenge!) in the team. Again, the key to success is good communication!
Calculating the metric
The total number of code reviews (PRs) merged for the selected period is considered. The PRs are then aggregated, by day, week, month, or sprint (depending on the selected mode), and the total number of reviews is compiled. An average is then calculated according to the number of PRs considered in the day, week, month, or sprint concerned. Finally, the average score visible at the top of the graph is an average of the averages, again depending on the selected display mode.
