The tick values are currently chosen regardless of the format, and then the
format is imposed on the chosen values. So, to handle numbers smaller than
1, you would want a format like '#.##'.
If you only have 0 values in your data (or only one single value), then the
chart doesn't know how to scale the axis, so it chooses arbitrarily. But
you can override this by specifying a viewWindow option for the axis with
min and max values. You could also specify minValue and maxValue to get
the same effect in this case.
The best way to get exactly the ticks that you want, with the formatting
you want, is to specify the ticks option. E.g. vAxis: { ticks: [ 0, 1, 2,
3, 4, 5 ] } Each value could be replaced by an object to specify both the
value and the formatted representation. For example, if one of your tick
values was 1/3, you could put this in your ticks array: { v: 1 / 3, f:
'0.33' }.
