Multiple 2D contour plots in a single 3D plot

Please I want the 2D contour plots to be arranged along either the X or Y axis. That is, the Z-axis of 45, 75, and 90 should rather be placed in either the X or Y-axis.
Kindly see the code I'm currently using below. Thank you
[y,x] = meshgrid(2:1:8,0:2.5:7.5);
Z1=All_CL(:,1:4)';
Z2=All_CL(:,5:8)';
Z3=All_CL(:,9:12)';
set(gcf,'position',[10,50,605,396]);
set(gca,'position',[0.15 0.25 0.8 0.60],'fontname','times new roman','fontsize',20);
set(gca,'xtick',0:2.5:7.5,'ytick',2:1:8,'ztick',30:15:90,'clipping','off');
[~,h] = contourf(x,y,Z1,25,'edgecolor','none'); % plot contour at the bottom
h.ContourZLevel = 90;
[~,h] = contourf(x,y,Z2,25,'edgecolor','none'); % plot contour at the bottom
h.ContourZLevel = 75;
[~,h] = contourf(x,y,Z3,25,'edgecolor','none'); % plot contour at the bottom
h.ContourZLevel = 45;
colormap(jet)
hcb=colorbar;
hold off
view(3)
camup([0 0 0])
zlim([30 90]);
caxis([0.05 2])

Hi,
As per my understanding, you will not be able to do this. There is no Property as such.
You are plotting contour on XY axis so its Z axis is empty. Now you want to fill that with some value "h.ContourZLevel", which is the height of that plot.
But if you want to change X or Y values, it is not valid to change existing values of Data.
Hope this Helps!

Hi,
you may use this camup at last:
x = linspace(-2*pi,2*pi);
y = linspace(0,4*pi);
[X,Y] = meshgrid(x,y);
Z1 = sin(X) + cos(Y);
Z2 = cos(X) + cos(Y);
Z3 = sin(X) + sin(Y);
[~,h] = contourf(x,y,Z1,25,'edgecolor','none'); % plot contour at the bottom
h.ContourZLevel = 90;
hold on
[~,h] = contourf(x,y,Z2,25,'edgecolor','none'); % plot contour at the bottom
h.ContourZLevel = 75;
hold on
[~,h] = contourf(x,y,Z3,25,'edgecolor','none'); % plot contour at the bottom
h.ContourZLevel = 45;
view(3)
camup([-1 0 0]); %rotate axis
Hope this helps!
