hi... i am trying to plot the contours on "surf" graph by following code %data x=[0.01 0.02 0.04 0.06 0.09 0.17 0.29 0.51 0.67 0.84 1.07 1.44 1.72 2.04 2.50 3.06 3.69 4.45 5.36 6.64 8.60 11.80 15.08 18.83 23.45 26.49 28.99 31.85 36.63 39.46 42.12 46.56 51.45 56.57 60.06 64.38 69.71 75.62 81.45 86.72 91.27 94.54 96.98 98.32 99.01 99.48 99.74 99.99]; y=[31.85 31.84 31.81 31.79 31.76 31.68 31.56 31.35 31.18 31.01 30.78 30.42 30.14 29.81 29.36 28.79 28.16 27.40 26.50 25.22 23.25 20.06 16.78 13.03 8.41 5.37 2.87 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01]; sd==[-3.80 -3.70 -3.60 -3.50 -3.40 -3.30 -3.20 -3.10 -3.00 -2.90 -2.80 -2.70 -2.60 -2.50 -2.40 -2.30 -2.20 -2.10 -2.00 -1.90 -1.80 -1.70 -1.60 -1.50 -1.40 -1.30 -1.20 -1.10 -1.00 -0.90 -0.80 -0.70 -0.60 -0.50 -0.40 -0.30 -0.20 -0.10 0.00 0.10 0.20 0.30 0.40 0.50 0.60 0.70 0.80 0.90]; axes('FontSize',16,'LineWidth',2); [x_new,y_new,V]=Myplot3D(x,y,sd); h=surf(x_new,y_new,V,'LineStyle','none'); hold on contour(x_new,y_new,V,'ShowText','off','LineWidth',2,'LineStyle','-','Fill','on','LevelStep',0.5);
