The problem seems to come from line 267 in this example. It looks like the "sec" argument is not getting passed to the C library correctly? 0.0 becomes something like 4.2439915819305446e-314, which I think causes the later problems. Perhaps there is something wrong with the fortran bindings for plctime? I would appreciate it if a fortran expert could take a look. -Hazen ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Plplot-devel mailing list Plplot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/plplot-devel
