How can I create a plot where the graph shifts as the data extends?

Hey all,
I want to make a pressure vs time graph that shifts the graph over to the right as time extends. I don't want to keep the old data in view. How can I do this?
Here's the current code:
hold on
for i=1:21598 %number of data points
ylim([0 60])
plot((data.time(i)-datenum(2013,01,00)),data.P(i));
drawnow;
pause(.1);
end
Right now the code plots the data, but keeps auto sizing the graph as the number of points increase. It also gets really slow as more points are added.

Does this help?
figure
hold on
dd = data.time - datenum(2013,01,00);
for i=1:21598 %number of data points
plot(dd(i),data.P(i));
ylim([0 60])
drawnow;
pause(.1);
end

I solved plotting and then write:
xlim([i-50,i+50])
Let me know if this helps, Fabrizio.

a = plot(((data.time(1)-datenum(2013,01,00)),data.P(1));
for i = 1:21598
set(a,'Xdata',data.time(i)-datenum(2013,01,00)),'YData',data.P(i))
axis([desired_xmin, desired_xmin+desired_range, 0 60])
drawnow
end
