노트: Frequency polygon is a line graph drawn by joining all the midpoints of the top of the bars of a histogram. Therefore usage of this command is the same as usage of Histogram Command.

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.
예: `FrequencyPolygon({0, 1, 2, 3, 4, 5}, {2, 6, 8, 3, 1})` creates the corresponding line graph.

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.
노트: For further examples see Histogram Command.
