A style which appends an |x filter| which discards all but each $n$th input coordinate. \index{Downsampling} + This downsampling works fairly well. It can be used to reduce a huge amount of coordinates from an input file. In this case, you should also set |filter discard warning=false| to avoid repeated notifications about skipped coordinates and |unbounded coords=discard| such that \PGFPlots\ should silently forget any discarded points (rather than generated interrupted plots). + Note that there is also a |mark repeat| style which applies the same operation to plot marks only. \paragraph{Technical note}: this style usually applies to $x$ coordinates (i.e.\ it counts $x$ coordinates).
