#142 IndexOutOfBounds exception in Dynamic Chart

[Seva Batkin]

I have a JPanel using GridLayout which contains
two JFreeChart objects. They are both time
based and are dynamically updated by the a
single thread. Every time i run it I get the
IndexOutOfBounds exception. It doesn't actually
stop the process but seems annoying
nontheless.

java.lang.IndexOutOfBoundsException: Index: 87,
Size: 87
