Matlab uses griddata three-dimensional interpolation, and then draw contourf to show that the cloud image is incomplete, what should I do?

Matlab draws contourf using known data. The contourf map displayed after using griddata griddata is incomplete and is truncated. How can it be displayed completely?
[X1,Y1,Z1]=griddata(x,y,f, linspace(min(x),max(x),1000),linspace(min(y),max(y),1000)','v4');
contourf(X1./1000,Y1./1000,Z1)

I manually modify the display range of x y every time, but the inappropriate range will distort the image, which is not a good method.
[X1,Y1,Z1]=griddata(x,y,fx,linspace(min(x),max(x),2000),linspace(min(y)-600,max(y)+600,2000)','v4');

Why do you say that? What is missing or truncated from the image that you posted that you expected / wanted to see?
