plotyy x axis does not match

I am using plotyy function to draw two curves, one line the other bar using

[ax]=plotyy(X1,Y1,X2,Y2,'plot','bar')

I want the bar to be upside down, I added:

set(ax(2),'ydir','rev');

I want both axes to be date axis; I added;

   datetick('x')
but xticks are overlapping; and if I turn off the second one; then they are not matching at all. Can any body help me solve this problem?

Try getting rid of the ticks on one x-axis (the one that hasn't been dateticked):

set(ax(2),'XTick',[])

You may also want to ensure that the limits are the same:

xl = get(ax(1),'XLim');
set(ax(2),'XLim',xl)

(I'm not sure which is axis 1 and 2, so you may need to switch them.)
