This function adds a plot label to the upper left corner of a graph (or an arbitrarily specified position). It takes all the same parameters
draw_text, but has defaults that make it convenient to label graphs with letters A, B, C, etc. Just like
it can handle vectors of labels with associated coordinates.
draw_plot_label(label, x = 0, y = 1, hjust = -0.5, vjust = 1.5, size = 16, fontface = "bold", family = NULL, color = NULL, colour, ...)
String (or vector of strings) to be drawn as the label.
The x position (or vector thereof) of the label(s).
The y position (or vector thereof) of the label(s).
Font size of the label to be drawn.
Font face of the label to be drawn.
(optional) Font family of the plot labels. If not provided, is taken from the current theme.
