  plot(1:5, type="n", axes=FALSE, ann=FALSE)
  abline(v=3, col="lightgray")
  text(3, 3.5, expression(
    paste("Areas (", mu * m^2, ")", sep = "               ")))
  text(3, 3.0, expression(
    paste("Areas (", mu * m^2, ")", sep = "xxxx")))
  text(3, 2.5, expression(
    paste("Areas (", mu * m^2, ")", "xxxx")))
