<div dir="ltr"><div dir="ltr">Hi Toni,<div>The overlay procedure allows you to overlay as many plots as you want on one base plot. Here's an example from a script of mine:</div><div><div>map_n34sc_jja0 = gsn_csm_contour_map(wks_n34sc,n34sc_sst(6,:,:),scres) ; 6 = JJA 0 </div><div>o1 = gsn_csm_contour(wks_n34sc,n34sc_tas(6,:,:),scres2) </div><div>o2 = gsn_csm_contour(wks_n34sc,n34sc_psl(6,:,:),scres3) </div><div>overlay(map_n34sc_jja0,o1)</div><div>overlay(map_n34sc_jja0,o2)</div><div>draw(map_n34sc_jja0)</div></div><div>frame(wks)</div><div><br></div><div>When you say it did not work correctly, can you elaborate? </div><div><br></div><div>Also, if you are paneling, and the exact location of each plot from one frame to the next is not changing, you can try the following:</div><div><br></div><div>panres = True</div><div>panres@gsnFrame = False</div><div><br></div><div>gsn_panel(wks,grass,(/2,2/),panres)</div><div>gsn_panel(wks,shrubs,(/2,2/),panres)<br></div><div>gsn_panel(wks,trees,(/2,2/),panres)<br></div><div>frame(wks)</div><div><br></div><div>This will overlay the 3 sets of panel plots, titles and all. You would want to alter the opacity of the colors for the two overlaid plots.</div><div>Hope that helps!</div><div>Adam</div></div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Sep 12, 2018 at 11:51 AM Toni Klemm <<a href="mailto:toni-klemm@tamu.edu">toni-klemm@tamu.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space">Hello!<div><br></div><div>I emailed earlier (see below) about a complex graphics problem, plotting 3 variables in one Hovmueller plot and then four Hovmueller plots into one panel (I didn’t mention the panel).
