The map contains several important components. The main display is of the mainland EU territory that is covered by the available data. The legend is created once 'GO' is pressed and loads in the bottom left corner. It contains up to 36 different colours, each being a combination of the two variables being displayed on the map. The left and bottom edges of the legend show the class boundaries for the mapping, with the classes on each axis containing 1/6 of the values for that variable. The number within the square indicates the number of regions that are within that class. A black box indicates no regions exist on that map with that combination of values. Yellow indicates no data is available for these variables, usually because there is insufficient data in the FADN survey to report on that variable. It can also be a result of combining data from other incompatible datasets, for example combining NUTS regions with FADN regions.
