    Hi Vadim. Can you provide a project which reproduces this issue? What axis type do you use? Do you use unsorted data? Thanks in advance.
  • Kirey Vadim
    Hi. Unfortunately i can not share project, but can answer questions. Axis types are NumericAxis for Y, and DateAxis for X. I set candleDataSeries.setAcceptsUnsortedData(true); because i had few random crashes, but data comes from socket in order sorted by date. Meet that crash only once from nearly 300-500 launches i think

Hi Vadim,

Without project it would be hard to find cause of this issue. Based on stack trace I can only assume that it’s somehow related to using data which isn’t sorted in X direction but I’m not 100% sure so for now I just suggest you to ensure that you use sorted data in your data series.

Best regards,
Yura
