Function to plot a scatter plot where each point is coloured by its 2-dimensional density.

scatter_heatmap(
  xvalues,
  yvalues,
  xlabel = "x",
  ylabel = "y",
  xlim = NULL,
  ylim = NULL,
  alphaval = 1,
  colourPal = "inferno",
  suckInVals = T
)

Arguments

xvalues	X values
yvalues	Y values
xlabel	X axis label
ylabel	Y axis label
xlim	Vector including limits of the x axis
ylim	Vector including limits of the x axis
alphaval	The transparency of the points
colourPal	The colour palette name from viridis to use - default is Inferno
suckInVals	Points beyond the limits will be sucked in to the edge values to depict that there exists more beyond the edge of the plot. Default is TRUE.

Returns the ggplot2 plot

Examples

x = rnorm(n = 50000, mean = 2, sd = 1)
y = rexp(50000, 1)
