Display values on top of a barChart and for that matter all charts

[KobaKhit]

Hello. I started using the dc.js because it is an awesome way of condensing so many insights into one dashboard. It is the future of data visualization and has a lot of potential. So far I have multiple suggestions and will start with displaying values on top of bars. The issue I encounter is that I have either a rowChart or a barChart with ordinal x-axis. My goal is to display values on top of the bars while the ordinal labels stay under the x-axis. For the rowChart I was able to use the label function to concatenate bar labels and values. However, for the barChart it requires a lot of hacking (label function is not available for barCharts). Here is a stackoverflow question with a hacky answer for your reference. I think it should be a default option, something like dc.barChart('#Chart').displayValues(true). Related is displaying percentage in the pieChart, but Mike Precup came up with a nice workaround for that. So the values in the bars of a barChart is the hardest of all to achieve and, hopefully, either somebody develops a simple workaround or this feature is added in later commits. I as a intermediate user of javascript am not able to hack my way through and rely on the default options a lot. Thanks for attention.

Thanks for reporting this @KobaKhit, however this is a duplicate of #211.

I put a bounty on your SO question and hope to get a slightly less hacky solution. It is not terribly difficult and it's too bad no one contributed code for the earlier issue.

Keep those suggestions coming!
