FrequencyPolygon[ <List of Class Boundaries>, <List of Heights> ]

FrequencyPolygon[ <List of Class Boundaries>, <List of Raw Data>, <Boolean Use Density> , <Density Scale Factor> (optional) ]

FrequencyPolygon[ <Boolean Cumulative>, <List of Class Boundaries>, <List of Raw Data>, <Boolean Use Density> , <Density Scale Factor> (optional) ]

FrequencyPolygon[<List of Class Boundaries>, <List of Heights>]
Creates a frequency polygon with vertices in given heights. The class boundaries determine the x-coordinate of each vertex.

FrequencyPolygon[<List of Class Boundaries>, <List of Raw Data>, <Boolean Use Density>, <Density Scale Factor>(optional)]
Creates a frequency polygon using the raw data. The class boundaries determine the x-coordinates of vertices and are used to determine how many data elements lie in each class. The y-coordinate of a vertex is determined as follows
• If Use Density = true, height = (Density Scale Factor) * (class frequency) / (class width)
• If Use Density = false, height = class frequency
By default, Use Density = true and Density Scale Factor = 1.
FrequencyPolygon[ <Boolean Cumulative>, <List of Class Boundaries>, <List of Raw Data>, <Boolean Use Density> , <Density Scale Factor> (optional) ]
If Cumulative is true this creates a frequency polygon where each vertex y-coordinate equals the frequency of the class plus the sum of all previous frequencies.
