2d Histogram Python. For example consider the following code. Import matplotlibpyplot as plt import numpy as np x nprandomrandn 100 print x y 2 nprandomrandn 100 print y plthist2d x y pltshow.
A 2D histogram contour plot also known as a density contour plot is a 2-dimensional generalization of a histogram which resembles a contour plot but is computed by grouping a set of points specified by their x and y coordinates into bins and applying an aggregation function such as count or sum if z is provided to compute the value to be used to compute contours. The class intervals of the data set are plotted on both x and y axis. Those chart types allow to visualize the combined distribution of two quantitative variables.
It is useful for avoiding the over-plotted scatterplots.
