2. Frequency (statistics) - Wikipedia

   en.wikipedia.org/wiki/Frequency_(statistics)

   A histogram is a representation of tabulated frequencies, shown as adjacent rectangles or squares (in some of situations), erected over discrete intervals (bins), with an area proportional to the frequency of the observations in the interval. The height of a rectangle is also equal to the frequency density of the interval, i.e., the frequency ...

3. Plot (graphics) - Wikipedia

   en.wikipedia.org/wiki/Plot_(graphics)

   Very complex graph: the psychrometric chart, relating temperature, pressure, humidity, and other quantities. Non-rectangular coordinates: the above all use two-dimensional rectangular coordinates ; an example of a graph using polar coordinates , sometimes in three dimensions, is the antenna radiation pattern chart, which represents the power ...

5. Statistical graphics - Wikipedia

   en.wikipedia.org/wiki/Statistical_graphics

   Statistical graphics have been central to the development of science and date to the earliest attempts to analyse data. Many familiar forms, including bivariate plots, statistical maps, bar charts, and coordinate paper were used in the 18th century.

6. Data analysis - Wikipedia

   en.wikipedia.org/wiki/Data_analysis

   Frequency distribution: Shows the number of observations of a particular variable for a given interval, such as the number of years in which the stock market return is between intervals such as 0–10%, 11–20%, etc. A histogram, a type of bar chart, may be used for this analysis. [55]

7. V-optimal histograms - Wikipedia

   en.wikipedia.org/wiki/V-optimal_histograms

   A v-optimal histogram is based on the concept of minimizing a quantity which is called the weighted variance in this context. [1] This is defined as = =, where the histogram consists of J bins or buckets, n j is the number of items contained in the jth bin and where V j is the variance between the values associated with the items in the jth bin.

8. Histogram - Wikipedia

   en.wikipedia.org/wiki/Histogram

   In a histogram, each bin is for a different range of values, so altogether the histogram illustrates the distribution of values. But in a bar chart, each bar is for a different category of observations (e.g., each bar might be for a different population), so altogether the bar chart can be used to compare different categories.

9. Radar chart - Wikipedia

   en.wikipedia.org/wiki/Radar_chart

   The radar chart is a chart and/or plot that consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points.
