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

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
