Return data used for plotting a GatingSet

get_plot_data(
  gs,
  df = NULL,
  sample,
  subset,
  Ncells = NULL,
  spill = NULL,
  metadata = NULL,
  vartype = NULL
)

`gs`	a GatingSet
`df`	data.frame with columns `name` and `subset` containing sample and subset names respectively and columns with plot variables. Ignored if `NULL`. Otherwise supersedes parameters 'gs', 'sample', 'spill', 'metadata'.
`sample`	Names of samples from the GatingSet (as returned by `pData(gs)$name`)
`subset`	Names of subsets from the GatingSet (as returned by `gs_get_pop_paths(gs)`)
`Ncells`	number of cells to sample from the GatingSet
`spill`	spillover matrix. If NULL, uncompensated data is returned and used for gating.
`metadata`	a data.frame containing metadata associated to samples.
`vartype`	named character vector specifying variable type conversion. (either "factor", "integer" or "character") Must have a column `name` used for mapping.
