A histogram is used to approximate the probability density function of the particular variable. Many options are available in python for building and plotting histograms. NumPy library of python is useful for scientific and mathematical operations. In th
Plotting the number of different pixels with the same value of the red channel that ranges from 0 to 255 will give you a histogram that represents that red channel of the image. Similarly, you can have different histograms for different channels. Let's say you have a grayscale image. In ...
But you see here two problems, since the groups are not near the same size, some are shrunk in the plot. The second is I don’t know which group is which. To normalize the areas for each subgroup, specifying thedensityoption is one solution. Also plotting at a higher alpha level lets...
