First you needto initialize theGnuplotenvironment// Load a support library GaussGnuplot.dll from MTENGHOME?? dlibdlibraryGaussGnuplot;// Set local variableslocalnp,xpp,ypp,cp,titl,text;// Initialize an Gnuplot environmentdllcall-r GnuplotInit;Next, you need to create a plot window, for example// Create an output windownp=1;xpp=40;ypp=40;cp=1;dllcallGnuplotWindowRelative(np,xpp,ypp,cp);//1 plot number, 40% of screen size, centeredThen, an arbitrary set of plot creation statements can be used depending on the plot to be producedtitl=\dllcallGnuplotWindowTitle(np,titl);text=\dllcallGnuplotPut(np,text);...Finally, all collected plot elements can be shown bydllcallGnuplotShow(np);and Gnuplotenvironment need to be closed bydllcallGnuplotEnd;
