Hi Leo: Sorry if I missed this earlier in the thread, but what version of PLplot? If you are not doing so already, could you try the svn trunk version of PLplot? We are in the last stage of preparing that for our next release, and it has many bug fixes compared to the previous release. Just to simplify possibilities, could you try the psc device instead? The associated ps device driver has no external library dependencies. Alan __________________________ Alan W.
