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!

Hello,

Thank you for the response. But is there a way to plot countour in either XZ or YZ axis so that either Y or Z axis is empty for me to fill with that specific value.

[Shubham Rawat]

Hi,

Yes that value will be of the remaining axis value. e.g. if you are making contour on xz axis then the "h.ContourZLevel" value will be of y axis.

Hello,

Please that is what I want to know how to go about it. Like an example of how to directly plot in the XZ or YZ axis.

Thank you

Hi,

Simply change the parameters in the contour function:

For Example:

[~,h] = contourf(x,y,Z1,25,'edgecolor','none'); %this is for xy axis

[~,h] = contourf(x,Z1,y,25,'edgecolor','none'); %this is for xZ1 axis

Hope this helps!

Thank you for your response. Basically, I want to present my results (bottom figure) in the way of the figure on top rather. Please is there a MATLAB code with even random data that can be used for such plot? Thank you

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!
