Days surrounding

Choose the number of days surrounding the selected one for which you'd like to make the specified type of profile or chart. Days surrounding means a number of days with the current day in the middle. For example, three days surrounding means the day before, this day and the day after. Even numbers are increased by 1 automatically, so that you get the same number of days before and after this day. You don' t have to change this if you want to accept the default setting in the Preferences Profile dialog.
