A 2d density chart allows to visualize the combined distribution of two quantitative variables. The concept is always the same: one variable is represented on the X axis, the other on the Y axis. Then, the number of observations within a particular area of the 2D space is counted and represented by a color gradient.
Group two-dimensional points into hexagonal bins. Possible thanks to the
2d density with shading
Very close from the contour plot, but shading is used to make the link between layers.
Group two-dimensional points into rectangular bins. Possible thanks to the
