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
Steffen

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.
