GrADS uses X11 for its interactive display window, but it also has a batch mode, so you can create graphics without the use of X. We have developed an interface for Cairo to do the rendering, not only to the X window, but also to create png, ps, eps, pdf, and svg output. </div><div><br></div><div>The problem I am having is with the X rendering when using XQuartz. Everything looks right when I use the old (deprecated) X11 application on my Mac, but if I use XQuartz, I get an incomplete rendering, illustrated by two screen shots (links are given below.) The graphical elements are very basic, these plots contain nothing but line segments and filled rectangles. </div><div><br></div><div><a href="http://iges.org/jma/x11.png">http://iges.org/jma/x11.png</a></div><div><a href="http://iges.org/jma/xquartz.png">http://iges.org/jma/xquartz.png</a></div><div><br><div>The batch-mode renderings by Cairo are correct, and the non-Cairo version of GrADS does not exhibit the problem with the X window display, so I am pretty sure that Cairo and XQuartz are not playing well together. </div><div><br></div><div>I am running Mac OS X 10.7.5. When running the old X11 application, the version information in the "About X11" window says: XQuartz 2.6.5 (xorg-server 1.10.6). When running XQuartz, the version numbers are more recent: XQuartz 2.7.4 (xorg-server 1.13.0). The Cairo version is 1.12.8.</div><div><br></div><div>I searched through my 2-yr archive of forum emails and found nothing related to rendering problems with XQuartz. Any suggestions or ideas about what might be going wrong would be most welcome. </div><div><br></div><div>--Jennifer</div><div><span class="Apple-style-span" style="font-size: 12px; "><br></span></div><div><span class="Apple-style-span" style="font-size: 12px; "><br></span></div><div><span class="Apple-style-span" style="font-size: 12px; ">--</span></div><div><div apple-content-edited="true"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; font-size: 12px; "><div>Jennifer M.
