class_docstr: Displays many line strips of equal length, with the option to add new
  vertex data to one end of the lines.
  
  Parameters
  ----------
  n_lines : int
      The number of independent line strips to draw.
  line_size : int
      The number of samples in each line strip.
  dx : float
      The x distance between samples
  color : array-like
      An array of colors to assign to each line strip.
  pos_offset : array-like
      An array of x, y position offsets to apply to each line strip.
  columns : int
      Arrange line strips into a grid with this number of columns. This
      option is not compatible with *pos_offset*.
  cell_size : tuple
      The x, y distance between cells in the grid.
