How to represent two different quantities in the same 3d figure?

Hi guys! Do you know how can I represent two 3d plots in the same figure, using two different z-axis?

Best!

Sure, just use two axes() with overlapping Position values.

This is not something you should use subplot() for, as subplot() is designed for not overlapping the axes.

Note: if the two different plots need different color maps then you will need to do additional work.

One simple example:

x1 = [0:.1:40];
y1 = 4.*cos(x1)./(x1+2);
z1=2*sin(x1);
x2 = [1:.2:20];
y2 = x2.^2./x2.^3;
z2=20*sin(x2);

hl1 = line(x1,y1,z1,'Color','r');
ax1 = gca;

set(ax1,'XColor','r','YColor','r',...
    'XTickLabel',{},'YTickLabel',{},...
    'XTick',[],'YTick',[])

ax2 = axes('Position',get(ax1,'Position'),...
           'Color','none',...
           'XColor','k','YColor','k');

hl2 = line(x2,y2,z2,'Color','k','Parent',ax2);

view(ax1,30,30)
view(ax2,30,30)

zt2=get(ax2,'ZTickLabel');
zt1=get(ax1,'ZTickLabel');

set(ax2,'ZTickLabel',{},'ZTick',[])

set(ax1,'ZTickLabel',[zt1 blanks(size(zt1,1))' zt2])

Both x and y axes are common so they only appear once, I don't know how to move the z tick labels to the other side so I just put the labels side by side separated by a blank space.
