p2y needs to be an exported function with a canvas argument #27
Description
p2y has been an internal function in plot.wblr. It distinguishes between canvas formats by use of the log graphics option. This function is very useful for annotation after plot generation, but there is need for it to be called based on the canvas that the user sees. The graphics option does not exist outside of the completed plot call, and it is not intuitive for most users.
