Plotting interpolated values as filled contours

Hi Ladys and Gends.

I've the task to plot interpolated values. As you can see in the pictures, one figure is working very well.

However two of these three dont.

I dont know why.

Also, here is my Code:

Maybe someone has an idea, how to adjust the code.

Best

It would help if you post the code instead of a picture of code.

xi=0:2:650; %aufspannen koordinatensystem
yi = 0:2:415;

figure(10);
x=log10(porosity);
y=3.0227*x-12.902;
[XI,YI] =meshgrid(xi,yi);
ZI = griddata(reservoir(:,1),reservoir(:,2),y,XI,YI, 'v4');
v = (min(y) : 0.2 : max(y));
[c,h] = contour(XI,YI,ZI);
clabel(c,h);
contourf(XI,YI,ZI,v);
set(colorbar,'yColor','b');
title('Interpolated scattered logarithmic permeability (entire domain)');
xlabel('x-coordinates [m]');
ylabel('y-coordinates [m]');

figure(11); %das funktioniert noch nicht richtig
[XI,YI] =meshgrid(xi,yi);
ZI = griddata(reservoir(:,1),reservoir(:,2),reservoir(:,3),XI,YI, 'v4');
v = min(reservoir(:,3)) : 2 : max(reservoir(:,3));
[c,h] = contour(XI,YI,ZI);
clabel(c,h);
contourf(XI,YI,ZI,v);
colorbar('Direction','reverse');
set(colorbar,'yColor','g');
title('Interpolated scattered porosity (entire domain)');
xlabel('x-coordinates [m]');
ylabel('y-coordinates [m]');

figure(12); %das glaube ich auch nicht
x2=porosity;
y2 = -1720.2091*x2 + (2548.5491); %ich weiß nicht, ob die density-Werte stimmen
[XI,YI] =meshgrid(xi,yi);
ZI = griddata(reservoir(:,1),reservoir(:,2),y2,XI,YI, 'v4');
v = min(reservoir(:,4)) : 0.2 : max(reservoir(:,4));
[c,h] = contour(XI,YI,ZI);
clabel(c,h);
contourf(XI,YI,ZI,v);
colorbar;
colorbar('Direction','reverse');
set(colorbar,'yColor','m')
lim = caxis;
caxis([00 2500]); %hier hab ich versucht die Colorbargrenzen zu versetzen aber das hat iwie nicht funktioniert
title('Interpolated scattered density (entire domain)');
xlabel('x-coordinates [m]');
ylabel('y-coordinates [m]');

okay, i got it. Just change the aray in v between the min and max.

Nice
