Description
This is probably not a bug, but we wanted to point it out in case that it could be. When a user with enough permissions, logs in and goes to the overview page, the legends can be clicked to show or hide the information of the cronological statistic. However, once the autorefresh or the refresh of the statistic is carried, the hidden/shown legends of the statistic are cleared, displaying all the information as it was initially when the page is loaded.
