I want to control only the lower limit of the axis and not the upper. I want the upper to be automatic. Is there any way to do it with set?

xlim([2 inf])
ylim([4 inf])

I did finally this. If I want for example my lower limit to be 2:
limsy=get(gca,'YLim');
set(gca,'Ylim',[2 limsy(2)];

The solution worked great for me:
limsy=get(gca,'YLim');
set(gca,'Ylim',[2 limsy(2)];
Quick question, what does the 2 in limsy(2) indicate. I feel as if I should know the answer but it is eluding me at the moment.
Thanks!

No.
You could probably work something up using a listener or two to detect changes to the xdata or ydata and to set() the xlim and ylim as appropriate. I wouldn't bother doing it that way, though.
