Function cones is similar to Bars
but draw cones. The sample code is:
int sample(mglGraph *gr) { mglData ys(10,3); ys.Modify("0.8*sin(pi*(2*x+y/2))+0.2*rnd"); gr->Light(true); gr->SetOrigin(0,0,0); gr->SubPlot(3,2,0); gr->Title("Cones plot"); gr->Rotate(50,60); gr->Box(); gr->Cones(ys); gr->SubPlot(3,2,1); gr->Title("2 colors"); gr->Rotate(50,60); gr->Box(); gr->Cones(ys,"cbgGyr"); gr->SubPlot(3,2,2); gr->Title("'#' style"); gr->Rotate(50,60); gr->Box(); gr->Cones(ys,"#"); gr->SubPlot(3,2,3); gr->Title("'a' style"); gr->SetRange('z',-2,2); // increase range since summation can exceed [-1,1] gr->Rotate(50,60); gr->Box(); gr->Cones(ys,"a"); gr->SubPlot(3,2,4); gr->Title("'t' style"); gr->Rotate(50,60); gr->Box(); gr->Cones(ys,"t"); gr->SubPlot(3,2,5); gr->Title("'4' style"); gr->Rotate(50,60); gr->Box(); gr->Cones(ys,"4"); return 0; }
