Make a contourf plot beautifuller

Hello,

I have a question regarding the contourf plot in Matlab.

With my script:

    f=figure(2);
    fontSize=20;
    f.Position(3:4)=[1280 1080];
    %
    contourf(x,y,T,15)
    clabel(contourf(x,y,T,15,"-b"),'FontSize', fontSize)
    cb= colorbar;
    c=turbo(20);
    colormap(c);
    shading interp
    set(gca,'ydir','reverse')
    set(gca,'FontSize',fontSize)
    set(cb,'FontSize',fontSize)
    set(gca,'FontSize',fontSize)
    xlabel('X/ m','FontSize', fontSize)
    ylabel('Y/ m','FontSize', fontSize)

I get this plot:

It's not beaufifull.

I would like create something like this:

Is it possible to smooth the contourf plot to create a better plot?

Would it be also possible to achive a plot without filled areas, only with colored isolines? Like this:

With best regards

The first one (with or without contour lines) is possible with a combination of the surf and view functions —

[X,Y,Z] = peaks(50);

figure
surf(X, Y, Z)
shading('interp')
view(0, 90)

The second is simply a contour plot —

figure
contour(X, Y, Z, 'LineWidth',1.5)
Ax = gca;
Ax.Color  = [1 1 1]*0.7;

Combining them —

Zoffset = 2;

figure
surf(X, Y, Z)
shading('interp')
hold on
contour3(X, Y, Z+Zoffset, 'LineWidth',2)
hold off
view(0, 90)

EDIT — Corrected Errors.
