No, not without being creative...
A quick hack:
http://chart.apis.google.com/chart?cht=bhs&chs=300x60&chds=1,10&chm=tSchool+0,FF0000,0,0,13|tSchool+1,FF0000,0,1,13&chd=t:2.0,2.0|6.0,4.0
You'll see that I added an extra dataset and applied the text markers
to the first dataset. You'll have to tweak the relative sizes (keeping
the total equal to your original values) in order to get the text
positioned more to your liking. Again, it's a work-around, but it
might a better option if you don't want to use Y-Axis labels (as shown
in the bar charts here:
http://code.google.com/apis/chart/#line_bar_pie_colors
).
