Adds the coordinate labels to each panel based on the location of the slice along the slicing axis (e.g., z = 15)

Usage

annotate_coordinates(x = "right", y = "bottom", ...)

x: the x position of the coordinate label. If numeric, it is assumed to be the pixel position along the x axis (e.g., 26). In addition, convenience values of "left", "right", or "q[1-100]" can be used to look up the left-most, right-most, or quantile-based positions along the x axis.
y: the y position of the coordinate label. If numeric, it is assumed to be the pixel position along the y axis (e.g., 26). In addition, convenience values of 'top', "bottom", or "q[1-100]" can be used to look up the top-most, bottom-most, or quantile-based positions along the y axis.
...: any other arguments to ggplot2::annotate, which will be passed through to each panel
