Nonpar Density estimates a smooth nonparametric bivariate surface that describes the density of data points. The plot adds a set of contour lines showing the density (Example of Nonpar Density). The contour lines are quantile contours in 5% intervals. This means that about 5% of the points are below the lowest contour, 10% are below the next contour, and so on. The highest contour has about 95% of the points below it.

Press Shift and select Nonpar Density from the Bivariate red triangle menu. Enter a larger value than the default 51 points.
