Hi,
I am building a chart that uses SegmentedTimeline and shows financial data across multiple days. The segmented timeline starts from 10AM thru 4PM and base time line is a monday thru friday timeline. The chart performs well as long as all the data is between 10AM-4PM. But when I have some data outside this range, the AWT thread becomes busy drawing the chart. The chart redraw takes lot of time. Jstack shows the following stack trace for the thread,

I have checked the graph without the segmented timeline, and the graph performs well. Please let me know if I am going in the wrong direction.
Thanks,
Rambabu.
