Ylim on plotyy - setting min value but leaving max automatic

I am using plotyy to plot a graph with 2 y-axis

[AX1,H1,H1] = plotyy(x,y1,x,y2,'plot');

I want the Ylims for both axes to be automatic, except I always want the min y value to be zero. I thought of using something below, but not sure how the get the current (automatically worked out) max value.

 set(AX1(1),'YLim',[0  ??],'FontSize',10);

any suggestions?

Thanks Jason
