Setting axes with center in origin (0,0) in plotted variables.

Hey community, I have two variables with x 1 double data. I am to plot these two in a plot, but would like to have the axes to be intersecting each other in origin (0,0). Instead in the axes are shown with intersecting at for example (-2000,-6), my lowest x-value is -1200, lowest y-value is -6. Here it would be great to have the x-axis through y=0, so that differences from y=0 easily can be seen graphically.
How would I do that, is there a command you could use in the script written, to make it move the axes? I have a large script to evaluate a lot of graphs in, so a MATLAB-command would be preferable to a tool in the figure builder.
The (simple) code used is as following:
%%person5 - Puls
hold on
plot(person5_ethanol_ekgpuls_tid,person5_ethanol_ekgpuls,'g.-')
xlabel('Tid/Sek')
ylabel('Blodtryk/MmHg')
title('Forsøgsperson #5 Ethanol Ekg Puls')
Hope that my question is understandable and that it can be done.

I am sure you are aware of the most straightforward solution to this is now available directly through MATLAB's axes option:
ax = gca;
ax.XAxisLocation = 'origin';
ax.YAxisLocation = 'origin';

Why are you sure the OP was aware of this? If that was the case, the question probably would not have been posted.

The simplest soution to this problem is
set(gca, 'XAxisLocation', 'origin', 'YAxisLocation', 'origin')
