Support non Time Series charting and handle data gap more gracefully for Chukwa charts
--------------------------------------------------------------------------------------

                 Key: HADOOP-5035
                 URL: https://issues.apache.org/jira/browse/HADOOP-5035
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/chukwa
         Environment: RedHat 5.1, Java 6
            Reporter: Eric Yang
            Assignee: Eric Yang


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.
