I cannot reproduce this problem. In jqt (which I think is what you are using here), if you run:
open 'jzplot' and then find the definition which begins with qt_jpg=: 3 : 0 -- can you insert echo statements there which show whether or not that verb is being used? If so, and if the data looks good there, this is probably an issue with qt on your system, rather than an issue with plot. (It's basically setting up for and calling writeimg_jqtide_ .)
