Dear list members, Michael Sharpe, <BR><BR>Michael's suggestions were both very useful and accurate. <BR>Thank you very much. <BR><BR>Actually I had to draw two figures. After some tests I came up <BR>with the code in this message. I put it here because I think <BR>it may help other people. <BR><BR>Luis <BR><BR>\usepackage{pstricks-add} %11/02/10<BR>\usepackage{pst-func} %09/07/10<BR>
