Show TimeSeries graph with 3 series in single line

[Jyothy]

I am using Time series graph. i always have 3 ranges critical, warning and clear. I need to draw a horizontal line at all 3 ranges

eg : value greater than 70 is critical , graterthan 40 and less than 70 is warning.
so i need to draw a line to specify the range in graph along wioth label.


Infact i can use 3 series and use TimesSeries Collection but it renders 3 diffrent series graph(with 3 diffrent colors) but, i need i single line but show all the 3 ranges with 3 diffrent colors or single line but 3 horizontal lines to specify ranges.


Thanks in advance

Have you tried adding one or more XYLineAnnotations to your plot?

I am using Jfree charts for rendering grpahs for monitoring solution of our application.

When is no data in database the data points in the TimeSeries are still joined in the graph.

For example: If data is stored from 2 PM to 5 PM and then from 5PM to 8PM data is not collected in database. but data point at 5PM and daat point at 8PM is joined which gives a wrong impression that data is collected during 5 - 8 PM.

How do i represent in the graph that data is not being collected during a particular period.

Thanks in advance
