Contour Plot when both x & y axis are in logscale

34 次查看(过去 30 天)
Can anyone help me to contour plot when both x & y axis are in logscale? Please see the figure.
I have coded like below but it didn't show logscale in both axis:
f=logspace(-3,0,100);
R0=logspace(-6,-2,100);
[X,Y]=meshgrid(f,R0);
%%%Main code body
....
.....
.....
Z=1+(gamma/(k*d^2))*(f.^2*delL+delR+2*R0.*X.*Gamma_func);
%%%%%%%
contour(X,Y,Z)

[x, y, z] = peaks;
x = x+4; y = y+4; z=z+8; % make it positive
figure
contourf(x, y, z);
colorbar
xlabel('x'); ylabel('y');
figure
%contour(log10(x), log10(y), z);
contourf(log10(x), log10(y), log10(z));
h2 = colorbar;
zt = h2.Ticks;
h2.TickLabels = "10^{"+string(zt')+"}";
% customize ticklabels
xt = xticks;
xticklabels("10^{"+string(xt')+"}");
yt = yticks;
yticklabels("10^{"+string(yt')+"}");
xlabel('x'); ylabel('y');
