e_x_axis_(e, serie = NULL, index = 0, formatter = NULL, margin = 0, ...)

e_y_axis_(e, serie = NULL, index = 0, formatter = NULL, margin = 0, ...)

e_z_axis_(e, serie = NULL, index = 0, margin = 0, ...)

e_x_axis(e, serie, index = 0, formatter = NULL, margin = 0, ...)

e_y_axis(e, serie, index = 0, formatter = NULL, margin = 0, ...)

e_z_axis(e, serie, index = 0, margin = 0, ...)

e_rm_axis(e, axis = c("x", "y", "z"))

e_axis_formatter(
  style = c("decimal", "percent", "currency"),
