MATLAB: Specify the style and color of a specific contour line

Question

Hi

I'm using the contourf function

contourf(x,y,z,[0:50:700],"ShowText","on")

I would like to make a specific coutour line thicker than the rest (i,e. 500)

Thanks

Answer 1

Just use contour once more

contour(x,y,z,[500 500],'linewidth',2,'color','red');
