Re: [Plplot-general] Using griddata with C++

[Paul W. B. <pa...@pu...>]

Hello again,

i discovered an error and now I am able to use the 2-dimensional array 
zg right.

The problem is still the griddata function. Something is wrong there. 
The running program is killed calling the griddata function.

Regards, Paul.

P.S.: My actual Code: (cd is a ContourableData object which extends 
Contourable_Data).

	pls = new plstream();
	pls->init();
	
	PLFLT *x, *y, *z;
	PLINT n = cd.count();
	x = cd.get_x();
	y = cd.get_y();
	z = cd.get_value();
	
	const PLINT nn = 20;
	PLFLT *xg = new PLFLT[nn];
	PLFLT *yg = new PLFLT[nn];
	PLFLT **zg;
	pls->plAlloc2dGrid(&zg, nn, nn);
	
	double step = 2*28/((double)n-1);
	for(int i = 0; i < nn; i++){
		double val = -28 + step*(double)i;
		xg[i] = val;
		yg[i] = val;
	}
	
	pls->griddata(x, y, z, n, xg, nn, yg, nn, zg, GRID_DTLI, 0.0);
