I want to plot two isosurface in one figure :Z1,Z2

 isovalues1 = 0:0.1:1;
 for i=1:length(isovalues1)
 isosurface(X,Y,Z,Z1,isovalues1(i));
 end
 hc(1,1)=colorbar;
 hc(1,1).Limits = [0 1];
 hold on
 ax = gca;
 isovalues2 = 40:10:100;
 for i=1:length(isovalues2)
   isosurface(X,Y,Z,Z2,isovalues2(i));
 end
 hc(1,2)=colorbar;
 hc(1,2).Limits = [40 100];

I don't know why this does not work properly. colorbar ranges are [0 1], [40 100] but they shows only one colorbar limits [0 100] How can I fix it?

You need to hold after the first isosurface for each axes

Each axes can have only one colorbar

See for example:

isovalues1 = 0:0.1:1;
isovalues2 = 40:10:100;
[X,Y,Z] = meshgrid(isovalues1);
Z1 = X + sin(Y) + Z.^2;
Z2 = (cos(X) + Y + sqrt(Z)) * 50;
subplot(1,2,1);
for i = 1 : length(isovalues1); isosurface(X,Y,Z,Z1,isovalues1(i)); hold on; end; hold off
view(8,71);
hc(1,1)=colorbar;
hc(1,1).Limits = [0, 1];
subplot(1,2,2);
for i = 1 : length(isovalues2); isosurface(X,Y,Z,Z2,isovalues2(i)); hold on; end; hold off
hc(1,2)=colorbar;
hc(1,2).Limits = [40, 100];
view(8,71);

I want to overlap two figures. and see cross section.

 isovalues1 = 0:0.1:1;
 for i=1:length(isovalues1)
 isosurface(X,Y,Z,Z1,isovalues1(i));
 end
 ax(1)=gca;
 hc(1,1)=colorbar;
 hc(1,1).Limits = [0 1];
 ax(2)=axes;
 set(gca, 'Color', 'none')
 view(3)
 isovalues2 = 40:10:100;
 for i=1:length(isovalues2)
   isosurface(X,Y,Z,Z2,isovalues2(i));
end
 alpha(.5)
 set(ax(2), 'XAxisLocation','top',...
             'YAxisLocation','right',...
             'Color','none');      
 hc(1,2)=colorbar;
 hc(1,2).Limits = [40 100];
