3D Stem Plot Help - Unable to do the graph

I have a set of data.

Day 1: Time=[0 0.1 2.3 4.5 9.0 10.9]; Temp=[22 22.2 24 27.6 21.2 19.3];

Day 2: Time=[0 1.2 2.3 6.4 7.9 9.8 12.1]; Temp=[21 23.2 25 24.3 26 22.6 19.0];

Day 3: Time=[0 3 3.6 8.4 12.1]; Temp=[19.9 21.7 23 21.4 18.7];

What i want to know is that how to plot Temperature (z axis) as a function of Day (x axis) and Time (y axis) using 'stem3'. Also i want to plot each day in different colors.

Please help. I am new and got stuck in this problem.

Time=[0 0.1 2.3 4.5 9.0 10.9 nan; ...  % data in uniform grid for concise representation
      0 1.2 2.3 6.4 7.9 9.8 12.1; ...
      0 3 3.6 8.4 12.1 nan nan];
Temp=[22 22.2 24 27.6 21.2 19.3 nan; ...
     21 23.2 25 24.3 26 22.6 19.0; ...
     19.9 21.7 23 21.4 18.7 nan nan];
Day=repmat([1:3]',1,size(Temp,2));       % day to match
h=[];                                    % grab the handles
for s=1:3
 h(s)=stem3(Day(s,:),Time(s,:),Temp(s,:),'fill');
 if s==1,hold on,end
end
set(h,{'color'},{'r';'g';'b'})           % set the colors

The "trick" is that to set the colors diffrently have to have separate stem objects; otherwise if just do

stem3(Day,Time,Temp,'fill','color','r');

, say, the color will be red for all and there's no way to change except all of them as the property is global for the object which is only one. There are two "children" handles only; one for the lines and another for the circles/markers.
