Heat Map

Heat Maps

Heat maps are graphic representations of data where individual values are color coded in a matrix. Values are often integers but may be a range of different values including locations, percentages, fractions etc. Heat maps are useful for comparing trends or patterns of similar or differing conditions. They can also help to visualize a catalogue of information that may be difficult to understand in real time. They allow for a matrix to be created which helps with organization, but can also create boundaries that may not exist.
