How would one update the plotted data without resting the figure axes labels and other format elements?

while t<=tf
for i=2:Nx
for j=2:Ny
T(i,j) =T(i,j)+dt*alpha*(((T(i-1,j)-2*T(i,j)+T(i+1,j))/dx^2)+((T(i,j-1)-2*T(i,j)+T(i,j+1))/dy^2));
history_T=cat(3,history_T,T);
end
end
t=t+dt;
X=[0:0.05:1];
Y=[0:0.05:1];
%% PLOT
surf(X,Y,T)
pause(0.01)
%% FORMATING ELEMENTS
xlabel('Width, $m$','Interpreter','Latex')
ylabel('Depth, $m$','Interpreter','Latex')
zlabel('Temperature, $T$','Interpreter','Latex')
xlim([0 Lx])
ylim([0 Ly])
zlim([0 100])
set (gca,'FontSize',10,'FontName','Times')
set(gcf,'color','w');
end
Where X and Y are row vectors and T is a matrix with dimensions (length(X),length(Y). T updated with every repitition of the while loop, producing a surf plot that changes accordingly.
The plot appears with default formatting until the final iteration where it formats it as I intend.
How can I instruct MATLAB to keep the formatting elements constant throught the iteration?
Many thanks.

Hi Josh,
Try placing the pause(0.01) line of code after %% Formating elements section i.e. after the set(gcf,'color,'w') and not after the surf(X,Y,T). This actually helps in pausing and viewing the surf plot after all the required formatting is done.
Hope it works!

Use hold on command
%% FORMATING ELEMENTS
figure(1)
xlabel('Width, $m$','Interpreter','Latex')
ylabel('Depth, $m$','Interpreter','Latex')
zlabel('Temperature, $T$','Interpreter','Latex')
xlim([0 Lx])
ylim([0 Ly])
zlim([0 100])
set (gca,'FontSize',10,'FontName','Times')
set(gcf,'color','w');
hold on
while
h = surf(X,Y,T);
pause(0.01)
delete(h);
end
hold off
