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.
