daspectthe window). This means setting the data aspect ratio to a value, including itscurrent value,daspect(daspect)can cause a change in the way the graphs look. See the Remarks section of theaxes description for more information.Examples The following surface plot of the function z = xe( – x2 – y 2 ) is useful to illustratethe data aspect ratio. First plot the function over the range –2 ≤ x ≤ 2, –2 ≤ y ≤ 2,[x,y] = meshgrid([-2:.2:2]);z = x.*exp(-x.^2 - y.^2);surf(x,y,z)0.50−0.5210−1−2−2−1012Querying the data aspect ratio shows how MATLAB has drawn the surface.daspectans =4 4 1-120
