Adding a vertical legend to the map
A map legend decodes the symbology used in a thematic GIS map for the reader. Legends are tightly integrated into QGIS, and in this recipe, we'll add the default legend from the map to the print composition.
Getting ready
Download the shapefile for this map from https://github.com/GeospatialPython/Learn/raw/master/Mississippi.zip and extract it to your qgis_data directory in a subdirectory named ms.
As with the previous recipes in this chapter, we will use the MapComposer library from https://github.com/GeospatialPython/Learn/raw/master/MapComposer.py, to simplify the creation of the map composition.
Place the file in the .qgis2/python directory within your home directory.
