Axis Labels!

I just want to suggest a useful feature that may be beneficial for many users of this module.
Axis labels will provide a better user experience by showing a title to represent each axis on the graph.

An example is shown in : http://www.pikemere.co.uk/blog/flot-tutorial-how-to-create-charts-with-m...
He has labels Rainfall, Months, Temperature beside the y and x axis.

The javascript library: https://github.com/markrcote/flot-axislabels

Hopefully someone has time to implement this feature into the Flot module, it would be awesome!
