function useDownSampler #

(dataSets: MaybeRef<DataSet[]>, maxPoints?: MaybeRef<number>) =>
ComputedRef<DataSet[]>

Parameters #

• dataSets MaybeRef<DataSet[]>

  The datasets to be downsampled

• maxPoints MaybeRef<number>

  The maximum number of points to allow in a single dataset

Returns ComputedRef<DataSet[]> #
