how to resize x and y axis

问题

How can I resize x and y axis ?

What I want, n more specific;

3900  |
  .   |
  .   |
  .   |
  60  |
      |
  30  |
      |_____________________________
      0  60  120  180  ...        3600  

What I have done ;

  a = [0:0.1:10000];
  plot(a);

What should I write so that resizing x and y axis is done as expected?

EDIT:

I do not want;

Check the documentation: http://www.mathworks.com/help/techdoc/ref/axis.html

axis([xmin xmax ymin ymax])

Another way:

xlim([0 3600])
ylim([0 3900])

http://www.mathworks.com/help/techdoc/ref/xlim.html

http://www.mathworks.com/help/techdoc/ref/ylim.html

I think for the step size it's

set(gca, 'XTick', [0:60:3600])
set(gca, 'YTick', [0:30:3900])
