It is common to have to insert a new legend. In most cases the legend will be centred on a particular position but in this example the legend has to be inserted between two or more points so that it adequately covers the correct area.Plot the positions from the text or follow the instructions on the tracing.Add the new legend, spreading it between the position. It is important to write clearly and to distinguish between capital letter and lower case. The size of the lettering should be proportionate to the size of the area legend covers on the chart. Always position legends horizontally unless the text of the NM instructs otherwise.
