Description

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.
