[Plplot-devel] How to advance the page ? - Answer, except for Windows

[Joachim W. <wu...@cr...>]

Sorry for the length of my previous mail,
there is a very short answer to the main question:

    plSetOpt("np", ""); // no pause between plots

So, the only task remains to implement this in the Windows binding,
using dev->nextPlot as indicated before.=20
