First you needto initialize theGnuplotenvironmentboolInit;Init=GnuplotInit();Next,you need to create a plot window, for exampleGnuplotWindowRelative(1,40,40,true);//1%u2013plot number, 40% of screen size, centeredThen,an arbitrary set of plot creation statements can be used depending on the plotto be producedGnuplotWindowTitle(1,\GnuplotPut(1,\...Finally, all collected plot elements can be shown byGnuplotShow(1);and Gnuplotenvironment need to be closed byGnuplotEnd();
