11.10 Sample ‘barh’ ¶

Function barh is the similar to bars but draw horizontal bars.

MGL code:

new ys 10 3 '0.8*sin(pi*(x+y/4+1.25))+0.2*rnd':origin 0 0 0
subplot 2 2 0 '':title 'Barh plot (default)':box:barh ys
subplot 2 2 1 '':title '2 colors':box:barh ys 'cbgGyr'
ranges -3 3 -1 1:subplot 2 2 2 '':title '"a" style':box:barh ys 'a'
subplot 2 2 3 '': title '"f" style':box:barh ys 'f'

C++ code:

void smgl_barh(mglGraph *gr)
{
	mglData ys(10,3);	ys.Modify("0.8*sin(pi*(2*x+y/2))+0.2*rnd");
	gr->SetOrigin(0,0,0);
	if(big!=3)	{	gr->SubPlot(2,2,0,"");	gr->Title("Barh plot (default)");	}
	gr->Box();	gr->Barh(ys);
	if(big==3)	return;
	gr->SubPlot(2,2,1,"");	gr->Title("2 colors");	gr->Box();	gr->Barh(ys,"cbgGyr");
	gr->SetRanges(-3,3,-1,1);	// increase range since summation can exceed [-1,1]
	gr->SubPlot(2,2,2,"");	gr->Title("'a' style");	gr->Box();	gr->Barh(ys,"a");
	gr->SubPlot(2,2,3,"");	gr->Title("'f' style");	gr->Box();	gr->Barh(ys,"f");
}
