Interval width histogram
Web1 day ago · Q: I would like to use R to generate a histogram which has bars of variable bin width with each bar having an equal number of counts. For example, if the bin limits are the quartiles, each bar would represent 1/4 of the total probability in the distribution.

Webfrequency: show the number of observations divided by the bin width. probability or proportion: normalize such that bar heights sum to 1. percent: normalize such that bar heights sum to 100. density: normalize such that the total area of the histogram equals 1. bins str, number, vector, or a pair of such values
WebDensity Histogram: Density histograms use areas to depict percentages. The width of each block indicates the size of the interval and the area of each block indicates what percentage of the data belongs to that category. The height indicates density or how crowded the block is.
