Usage

plot_cs_pts(
  cs_pts,
  crosswalk_id = NULL,
  x = "pt_id",
  y = "Z",
  color = NULL,
  size = 1,
  grid = FALSE,
  scales = "free_y"
)

cs_pts: data.frame of cross section points with columns hy_id, cs_id and columns for X and Y axises (i.e. "pt_id", "Z")
crosswalk_id: unique ID column name
x: character name of column in cs_pts to use for X axis
y: character name of column in cs_pts to use for Y axis
color: character name of column in cs_pts to color points on plot
size: numeric, size of the cs points, default is 1
grid: logical, if TRUE then use facet_grid, otherwise use facet_wrap. Default is FALSE (uses facet_wrap)
scales: Should scales be fixed ("fixed", the default), free ("free"), or free in one dimension ("free_x", "free_y")?
