subplot question between 2,1.xx and 2.9.12

[Tatsuro MATSUOKA]

The following simple code
***************** 
subplot(111);clg;
%
x=linspace(0,3*pi,301);
subplot(211);
xlabel("x \n");
ylabel("sin(x)\n");
axis([0 2*pi -1.1 1.1]);
plot(x,sin(x));
%
subplot(212);
xlabel("x \n");
ylabel("cos(x)\n");
axis([0 2*pi -1.1 1.1]);
plot(x,cos(x));
**********************
give the graph on octave 2.1.50 (cygwin)

but the same code on octave 2.9.12 on MCVC
give the graph 
http://www.geocities.jp/tmacchant/Files/sbptest2.png

The label and axis setting is ignored.
Instead of the above code
************************
subplot(111);clg;
%
x=linspace(0,3*pi,301);
subplot(211);
plot(x,sin(x));
xlabel("x \n");
ylabel("sin(x)\n");
axis([0 2*pi -1.1 1.1]);
drawnow;
%
subplot(212);
plot(x,cos(x));
xlabel("x \n");
ylabel("cos(x)\n");
axis([0 2*pi -1.1 1.1]);
drawnow;
****************************
gives the graph like

However, in this case, the octave 2.1.50 gives the graph
http://www.geocities.jp/tmacchant/Files/sbptest4.png

So I have to write a script for the both octave version
being consistent like following
****************************
subplot(111);clg;
%
x=linspace(0,3*pi,301);
subplot(211);
xlabel("x \n");
ylabel("sin(x)\n");
axis([0 2*pi -1.1 1.1]);
plot(x,sin(x));
xlabel("x \n");
ylabel("sin(x)\n");
axis([0 2*pi -1.1 1.1]);
drawnow;
%
subplot(212);
xlabel("x \n");
ylabel("cos(x)\n");
axis([0 2*pi -1.1 1.1]);
plot(x,cos(x));
xlabel("x \n");
ylabel("cos(x)\n");
axis([0 2*pi -1.1 1.1]);
drawnow;
******************************

However the code seems to be curious. I would like to
avoid such ugry code.  Does anyone know a good idea for
smart coding ?
