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). In case you want to apply it to something like |hist/data| or |quiver/u|, you can

A low--level (technical) key which allows to apply the |restrict * to ...| features also to something like |hist/data|.
For example,
- |@restrict to domain={hist/data}{}{0:1}{0}| applies the domain-restriction to the histogram-input |hist/data|. The final `|0|' means that it works as the key |restrict x to domain=0:1|, i.e.\ it skips everything which is outside of $[0,1]$. In a similar way,

|@restrict to domain={hist/data}{}{0:1}{1}| applies the functionality of |restrict x to domain*=0:1| to |hist/data|: it truncates values outside of $[0,1]$ to the domain's end-points.
The \meta{filter name} is expected to be a coordinate name like |x|, |y|, |z| (or |hist/data|).
