Y-axis labels don't show up properly when they're decimal values -- only the top-most value and zero appear

Y-axis labels need to show incremental values when they're decimals (less
than 1, greater than zero)

Any updates on this? This is the only hurdle preventing me from using it as I 
am rendering line charts with decimal values.

Try this:
                topValue: function(){
                        var topValue = 0;
                        var allData = this.allData().join(',').split(',');
                        $(allData).each(function(){
                            if(parseFloat(this,10)>topValue) topValue = parseFloat(this);
                        });
                        var topValue = Math.ceil(topValue) + '';
                        return (Math.ceil(topValue/Math.pow(10,topValue.length-1)))*Math.pow(10,topValue.length-1);
                },

This line solves the decimal problem, by simply rounding the numbers: var 
topValue = Math.ceil(topValue)

The next line makes the y-axis go higher than the the bars. It rounds up to 10 
to the power of the number of digits in your highest value.  If you have 10 y 
axis lables, then they will be nice round numbers (with only or two significant 
figures). A simple way to have 10 y axis lables is by setting your graph height 
to 300px when you call it).
