using subplot

I want to use subplot to plot some figure with the same x-axis range and i dont want to have separated. I want to plot it closely together by using a single a-axis.

I dont mean to plot all the data on a single plot, i actually need to put them (3 plots) one on top of the other and use the same a-axis but different y-axis

Then it's not subplot. Just use plot() with the hold on command.

t=1:0.1:10;
plot(t,0.1*t);
hold on;
plot(t,sin(t));

Thank you Jiang, i dont mean to plot all the data on a single plot, i actually need to put them (3 plots) one on top of the other and use the same a-axis but different y-axis;

Then, plotyy() can provide 2 y-axis on the left and right.
