通过将x轴划分成若干个单元并计算每个单元中的观察次数,可视化单个连续变量的分布。Histograms (geom_histogram) 通过每个条形(bar)来展示数目,frequency polygons (geom_freqpoly) 通过线条来展示数目。 Frequency 更适用于比较分布在一个分类变量的水平。 geom_freqpoly(mapping = NULL, data = NULL, stat = "bin"...
Frequency PolygonsFrequency polygons are analogous to line graphs, and just as line graphs make continuous data visually easy to interpret, so too do frequency polygons.To construct a frequency polygon, first examine the data and decide on the number of intervals, or class intervals, to use ...

Histograms are useful for showing the distribution of a single scale variable. Data are binned and summarized using a count or percentage statistic. A variation of a histogram is a frequency polygon, which is like a typical histogram except that the area graphic element is used instead of the ...
When a line chart is used to depict frequency distributions like a histogram, this is called a frequency polygon. Density curve A density curve, or kernel density estimate (KDE), is an alternative to the histogram that gives each data point a continuous contribution to the distribution. In ...
Found in our Compare Two Histograms template, a Frequency Polygon is a graph that is used to understand the actual shape of your distribution. Note that this is beneficial when you are comparing multiple data sets/multiple distributions.
