Hmmm, javascript doesn't come with sprintf and it's not exactly the most
fun routine to implement.
A much more javascript-friendly idea (and also easier to implement) is
for Timeplot to allow you to pass your own "labeling" function that
receives a number and spits out a string. So you can be responsible for
your own formatting.
That would be rather simple to implement.

You can do that right now:
var geometry = new Timeplot.DefaultValueGeometry({
max: 100,
min: 0
});
The geometry will alter itself in case the values are above or below the
max/min (Timeplot never plots stuff out of the plotting canvas), but if
you know that those values are above and below yours, it will just 'fix'
the geometry for you.
It can also be possible to add a flag for timeplot to avoid resizing the
geometry even if the values are above or below the min/max, but I never
came across a reason for that.
