> Chukwa charting only support time series data because the data structure is a HashMap of Long, Double.
> Long is the timestamp (xaxis), and Double is the yaxis value.  The data structure will be changed to HashMap of String, Double.
> This will add capability to plot xaxis with any data.
> If the yaxis value is not a number, the charting system should skip plotting for this data point.
