Reverse the X and Y axis values in a 3D plot
显示 更早的评论
I have used below code to plot a 3D plot.
f1=2 ; f2=1.8 ; .... ....
Pt=0:5:30;
A1=2*pi*del*f1*f1*Vt*Vt*10^18; A2=2*pi*del*f2*f2*Vt*Vt*10^18; .... ....
B=c^2*Pt*s*t;
K1=(A1./B)./10; K2=(A2./B)./10; .... ....
f11=[f1;f2;f3;f4;f5;f6;f7;f8;f9;f10]; K=[K10;K9;K8;K7;K6;K5;K4;K3;K2;K1]; Pt=[Pt;Pt;Pt;Pt;Pt;Pt;Pt;Pt;Pt;Pt];
figure,surf(Pt,f11,K);
In the 3D plot I need to reverse the X-axis (f) and Y-axis (K) values in reverse order.
Could you please tell me how to do it?

% An example:
[X,Y,Z] = peaks(30);
surfc(X,Y,Z)
colormap hsv
axis([-3 3 -3 3 -10 5])
% Reverse x and y axis
set(gca,'Xdir','reverse','Ydir','reverse')

doc flipud
doc fliplr
flip the data using one of the above.
maybe:
%Get the current axes data, flip it and set it
set(gca,'xdata',fliplr(get(gca,'xdata')))

fll would be the axes' 'ydata'.. axes doesnt; care what it was the variable called before.

My bad, that does error. Try this:
h = surf(magic(5));
pause(5); %look around
set(h,'ydata',flipud(get(h,'ydata')))
drawnow;
