What are x and y here?

Like "heatmap" is correct for "value Z As color against params x and y", but depending on what it is it there are more specific names - it doesnt look like a correlation matrix, but it does look like a 2D probability density. If youre not already using it, the answer is https://ggplot2.tidyverse.org/reference/geom_density_2d.html

@jpeelle @rstats I've heard this referred to as a "heatmap" or "density plot" (I prefer the former - a density plot to me is that "layered waves" type plot.)

How to generate this in #rstats depends on what your underlying data looks like, but I've had good success with #ggplot2, as well as dedicated packages for visualization of fitted models.
