Very good library. Thanks for creating.

I have faced an issue. For some of the time series data there are no results and its causing the chart not to render anything

Its helpful to show a message (configurable) when the chart is rendered but without any data

See http://jsbin.com/otaxef/35/edit for the problem

This is needed mostly when we are using .setData() function to render the chart from dynamically fetched data from server.
