For the trend in the job page I added a test to suppress the chart if there are not enough values, in the details view it is not yet implemented.
Thanks.
How does one use the task scanning functionality? (to search for TODO etc).
The task scanner has not been converted to the new API yet. It takes a little bit more time since some views need customization
While it is quite easy to hide that part of the chart I wonder what we should show in the empty space. Maybe this could be fixed together with JENKINS-59594.
