Jonathan,
That is my bad. Here is a simple self-contained test. I could plot 10000
in 40 seconds (Our goal is to bring down to 5 seconds) on my MacBook Pro (i5
CPU). If I increased number to 100K (that will be the upper limit for our
application), chart did not render in 6 minutes and I have to kill the program.
By the way, I am using JDK 8u102.
Thanks,
Tai
