[Plplot-general] Fast/slow plotting

[Torquil M. <to...@gm...>]

Hello,

I have a C++ program that simulates the movements of polygons. It runs a=20
plotting function e.g. every 100 iterations of the simulation. Why is it th=
at=20
when I use PLPLOT there is lots of flickering, but with PGPLOT it looks gre=
at=20
without any flickering? Is PGPLOT much faster than PLPLOT or am I doing=20
something wrong? With plplot it is too much flickering to be able to watch=
=20
the polygons move around. I have tried setting the xwin device options=20
nobuffering and sync, but there was no difference.

Here is a description of the code:

void new_page() {
	plclear();
	plbox("bcinst", 0, 0, "bcinst", 0, 0);
}

void plot() {
	new_page();
	{..calculate plot quantitie here...}
	{... some plline() functions...}
}
=09
int main() {
	plsdev("xwin");
	plinit();
	plenv(xmin, xmax, ymin, ymax, 1, -2);

	for(int i =3D 0; i !=3D i_max; ++i) {
		{...simulation_code here...}
		if(i % 100 =3D=3D 0) plot();
	}

	plend();
	return(0);
}
