 Multiple miniature topoplots in regular distances 
 
 ## Arguments:
 
-- `f::Union{GridPosition, Figure}`: Figure or GridPosition that the plot should be drawn into
+- `f::Union{GridPosition, GridLayout, Figure}`: Figure or GridPosition that the plot should be drawn into
 - `plotData::DataFrame`: DataFrame with data, needs a `time` column
 - `Δbin::Real`: A number for how large one bin should be. Δbin is in units of the `plotData.time` column
 - `combinefun` (default `mean`) can be used to specify how the samples within `Δbin` are combined.
