If you don't want to use a combination of color shading for your variable and then use a couple contour levels to indicate significance, you might want to look into using NCL (<A class="moz-txt-link-abbreviated" href="http://www.ncl.ucar.edu">www.ncl.ucar.edu</A>), which does have cross-hatching, etc. They have a lot of documentation, sample scripts, and an open searchable user forum to find answers or to ask questions. Maybe other users here know of other packages that can do the job.<BR> <BR> MJ<BR> <BR> <BR> Robert Burgman wrote: <BLOCKQUOTE cite="mid057A3F89-E84C-40C5-8DBF-3CFFF9BBE7B1@rsmas.miami.edu" type="cite"> <DIV style="margin: 0px;">Hello all,</DIV> <DIV style="margin: 0px;">Does any one know how to add cross hatching to a plot. For example, I have a color shaded plot of output ( SST anomalies ) from a calculation and wish to show areas of significance. I have seen examples of using shaded output with contours, but would like to keep the color shading.</DIV> <DIV style="margin: 0px;">Thanks,</DIV> <DIV style="margin: 0px;">Rob</DIV> <DIV style="margin: 0px; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; font-size: 12px; line-height: normal; font-size-adjust: none; font-stretch: normal; min-height: 14px;"><BR> </DIV> <DIV style="margin: 0px;">----------------------------------------------------</DIV> <DIV style="margin: 0px;">Dr. Robert Burgman</DIV> <DIV style="margin: 0px;">Division of Meteorology and Physical Oceanography</DIV> <DIV style="margin: 0px;">Rosenstiel School of Marine and Atmospheric Science</DIV> <DIV style="margin: 0px;">University of Miami MPO, MSC 237</DIV> <DIV style="margin: 0px;">4600 Rickenbacker Causeway</DIV> <DIV style="margin: 0px;">Miami, FL 33149</DIV> <DIV style="margin: 0px; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; font-size: 12px; line-height: normal; font-size-adjust: none; font-stretch: normal; min-height: 14px;"><BR> </DIV> <DIV style="margin: 0px;">Tel: (305) 421-4272</DIV> <DIV style="margin: 0px;">Fax: (305) 421-4696</DIV> <DIV style="margin: 0px;">Email: <A href="mailto:rburgman@rsmas.miami.edu"><FONT class="Apple-style-span" color="#0020e2">rburgman@rsmas.miami.edu</FONT></A></DIV> <DIV style="margin: 0px;">---------------------------------------------------</DIV> <DIV style="margin: 0px; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; font-size: 12px; line-height: normal; font-size-adjust: none; font-stretch: normal; min-height: 14px;"><BR> </DIV> <DIV style="margin: 0px; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; font-size: 12px; line-height: normal; font-size-adjust: none; font-stretch: normal; min-height: 14px;"><BR class="khtml-block-placeholder"> </DIV> </BLOCKQUOTE> <BR> </BLOCKQUOTE></DIV><BR></DIV></DIV></BODY></HTML>
