Not filtering your input data? grap's only intent is to typeset the data you feed it. 'coord' sets the ranges for the graph scales. It doesn't filter the data -- that's your job. (As a typesetting design device I might want to plot data points outside the graph axis limits -- grap rightly doesn't prevent me from doing that.)
