[flexcoders] Group displaying label for all dates in a month, or a range of date?

[Vishal]

I am using candlestick charts with category axis on the horizontal for 
displaying date, now I want group displaying the label for all the dates in a 
month or a range of date.

For all dates in Feb, I should display one label 'Feb' and similarly for other 
months.
or
For some dates like Feb 2, Feb 3, Feb 4, Feb 5, Feb 6 label should be Feb 2 - 
Feb 6


Once achieved I want to draw grid lines separating the labels formed in the 
above example.

Any pointers?

Thanks
