Hi Hadley, Well, the problem seems to be that ggplot is not recognizing the scale when set by scale_y_continuous, the maximum value stays exactly at the data range, irrespective of what I provide as range. I am not familiar yet with proto, therefore I do have some difficulty delving into the code to find out exactly what is wrong, but I hope you can tell if I am doing something pretty stupid, or f it is a feature or a bug...
