This will reproduce it:
x = -40:5:40;
y = ones(1,16);
[X,Y] = meshgrid(x,y);
z = @(x,y) bsxfun(@plus, tanh(x * 0.1).*0.1, 1.5*Y);
Z = z(X,Y);
figure(1)
mesh(Z)
grid on
qx = xlim;
axis([1 17 1 16 1.4 max(zlim)])
view([25 60])
xt = 1:4:length(x);
xtl = regexp(sprintf('%.0f ',linspace(-40, 40, length(xt))), ' ', 'split');
set(gca, 'XTick',xt, 'XTickLabel',xtl(1:end-1))
yt = 1:5:length(y);
ytl = regexp(sprintf('%.0f ',linspace(0, 4, length(yt))), ' ', 'split');
set(gca, 'YTick',yt, 'YTickLabel',ytl(1:end-1))
zt = linspace(1.40, 1.60, 5);
ztl = regexp(sprintf('%.2f ',zt), ' ', 'split');
set(gca, 'ZTick',zt, 'ZTickLabel',ztl(1:end-1))
yielding this plot:
Reproducing it exactly without knowing the code that created the original means that this code is not as efficient as I would like it to be. Nevertheless, it works.

I want the above mesh for the given below data can u help me in this regard as i'm not getting the exact scale for X and T in mesh:
x = [-1, -0.973, -0.911, -0.816, -0.691, -0.541, -0.372, -0.190, 0, 0.190, 0.372, 0.541, 0.691, 0.816, 0.911, 0.973, 1];
t = (0.01:0.01:0.1);
[X,T] = meshgrid(x,t);
Z = [1.4902 1.4904 1.4911 1.4920 1.4933 1.4947 1.4964 1.4983 1.5001 1.5020 1.5039 1.5056 1.5070 1.5083 1.5092 1.5098 1.5101;

mesh(Z)
xlabel('x'); ylabel('t')
zlabel(' z3 (x, t)')

For the axis scales to display correctly, use both mesh independent coordinates arguments in the mesh call:
mesh(X,T,Z)
That should do what you want.
